## NAME

git-config - Get and set repository or global options

## SYNOPSIS

git config [<file-option>] [type] [-z|--null] name [value [value_regex]] git config [<file-option>] [type] --add name value git config [<file-option>] [type] --replace-all name value [value_regex] git config [<file-option>] [type] [-z|--null] --get name [value_regex] git config [<file-option>] [type] [-z|--null] --get-all name [value_regex] git config [<file-option>] [type] [-z|--null] --get-regexp name_regex [value_regex] git config [<file-option>] --unset name [value_regex] git config [<file-option>] --unset-all name [value_regex] git config [<file-option>] --rename-section old_name new_name git config [<file-option>] --remove-section name git config [<file-option>] [-z|--null] -l | --list git config [<file-option>] --get-color name [default] git config [<file-option>] --get-colorbool name [stdout-is-tty] git config [<file-option>] -e | --edit

## DESCRIPTION

You can query/set/replace/unset options with this command. The name is actually the section and the key separated by a dot, and the value will be escaped.

Multiple lines can be added to an option by using the --add option. If you want to update or unset an option which can occur on multiple lines, a POSIX regexp `value_regex` needs to be given. Only the existing values that match the regexp are updated or unset. If you want to handle the lines that do not match the regex, just prepend a single exclamation mark in front (see also [EXAMPLES]).

The type specifier can be either --int or --bool, to make git config ensure that the variable(s) are of the given type and convert the value to the canonical form (simple decimal number for int, a "true" or "false" string for bool), or --path, which does some path expansion (see --path below). If no type specifier is passed, no checks or transformations are performed on the value.

The file-option can be one of --system, --global or --file which specify where the values will be read from or written to. The default is to assume the config file of the current repository, .git/config unless defined otherwise with GIT_DIR and GIT_CONFIG (see [FILES]).

This command will fail if:

1. The config file is invalid,

2. Can not write to the config file,

3. no section was provided,

4. the section or key is invalid,

5. you try to unset an option which does not exist,

6. you try to unset/set an option for which multiple lines match, or

7. you use --global option without $HOME being properly set.

## OPTIONS

--replace-all

  Default behavior is to replace at most one line. This replaces all lines matching the key (and optionally the value_regex).

--add

  Adds a new line to the option without altering any existing values. This is the same as providing ^$ as the value_regex in `--replace-all`.

--get

  Get the value for a given key (optionally filtered by a regex matching the value). Returns error code 1 if the key was not found and error code 2 if multiple key values were found.

--get-all

  Like get, but does not fail if the number of values for the key is not exactly one.

--get-regexp

  Like --get-all, but interprets the name as a regular expression. Also outputs the key names.

--global

  For writing options: write to global ~/.gitconfig file rather than the repository .git/config.

  For reading options: read only from global ~/.gitconfig rather than from all available files.

  See also [FILES].

--system

  For writing options: write to system-wide $(prefix)/etc/gitconfig rather than the repository .git/config.

  For reading options: read only from system-wide $(prefix)/etc/gitconfig rather than from all available files.

  See also [FILES].

-f config-file
--file config-file

  Use the given config file instead of the one specified by GIT_CONFIG.

--remove-section

  Remove the given section from the configuration file.

--rename-section

  Rename the given section to a new name.

--unset

  Remove the line matching the key from config file.

--unset-all

  Remove all lines matching the key from config file.

-l
--list

  List all variables set in config file.

--bool

  git config will ensure that the output is "true" or "false"

--int

  git config will ensure that the output is a simple decimal number. An optional value suffix of k, m, or g in the config file will cause the value to be multiplied by 1024, 1048576, or 1073741824 prior to output.

--bool-or-int

  git config will ensure that the output matches the format of either --bool or --int, as described above.

--path

  git-config will expand leading ~ to the value of $HOME, and ~user to the home directory for the specified user. This option has no effect when setting the value (but you can use git config bla ~/ from the command line to let your shell do the expansion).

-z
--null

  For all options that output values and/or keys, always end values with the null character (instead of a newline). Use newline instead as a delimiter between key and value. This allows for secure parsing of the output without getting confused e.g. by values that contain line breaks.

--get-colorbool name [stdout-is-tty]

  Find the color setting for `name` (e.g. `color.diff`) and output "true" or "false". `stdout-is-tty` should be either "true" or "false", and is taken into account when configuration says "auto". If `stdout-is-tty` is missing, then checks the standard output of the command itself, and exits with status 0 if color is to be used, or exits with status 1 otherwise. When the color setting for `name` is undefined, the command uses `color.ui` as fallback.

--get-color name [default]

  Find the color configured for `name` (e.g. `color.diff.new`) and output it as the ANSI color escape sequence to the standard output. The optional `default` parameter is used instead, if there is no color configured for `name`.

-e
--edit

  Opens an editor to modify the specified config file; either --system, --global, or repository (default).

## FILES

If not set explicitly with --file, there are three files where git config will search for configuration options:

$GIT_DIR/config

  Repository specific configuration file. (The filename is of course relative to the repository root, not the working directory.)

~/.gitconfig

  User-specific configuration file. Also called "global" configuration file.

$(prefix)/etc/gitconfig

  System-wide configuration file.

If no further options are given, all reading options will read all of these files that are available. If the global or the system-wide configuration file are not available they will be ignored. If the repository configuration file is not available or readable, git config will exit with a non-zero error code. However, in neither case will an error message be issued.

All writing options will per default write to the repository specific configuration file. Note that this also affects options like --replace-all and --unset. git config will only ever change one file at a time.

You can override these rules either by command line options or by environment variables. The --global and the --system options will limit the file used to the global or system-wide file respectively. The GIT_CONFIG environment variable has a similar effect, but you can specify any filename you want.

## ENVIRONMENT

GIT_CONFIG

  Take the configuration from the given file instead of .git/config. Using the "--global" option forces this to ~/.gitconfig. Using the "--system" option forces this to $(prefix)/etc/gitconfig.

See also [FILES].

## EXAMPLES

Given a .git/config like this:

    #
    # This is the config file, and
    # a '#' or ';' character indicates
    # a comment
    #

    ; core variables
    [core]
            ; Don't trust file modes
            filemode = false

    ; Our diff algorithm
    [diff]
            external = /usr/local/bin/diff-wrapper
            renames = true

    ; Proxy settings
    [core]
            gitproxy="proxy-command" for kernel.org
            gitproxy=default-proxy ; for all the rest

you can set the filemode to true with

    % git config core.filemode true

The hypothetical proxy command entries actually have a postfix to discern what URL they apply to. Here is how to change the entry for kernel.org to "ssh".

    % git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'

This makes sure that only the key/value pair for kernel.org is replaced.

To delete the entry for renames, do

    % git config --unset diff.renames

If you want to delete an entry for a multivar (like core.gitproxy above), you have to provide a regex matching the value of exactly one line.

To query the value for a given key, do

    % git config --get core.filemode

or

    % git config core.filemode

or, to query a multivar:

    % git config --get core.gitproxy "for kernel.org$"

If you want to know all the values for a multivar, do:

    % git config --get-all core.gitproxy

If you like to live dangerously, you can replace all core.gitproxy by a new one with

    % git config --replace-all core.gitproxy ssh

However, if you really only want to replace the line for the default proxy, i.e. the one without a "for …" postfix, do something like this:

    % git config core.gitproxy ssh '! for '

To actually match only values with an exclamation mark, you have to

    % git config section.key value '[!]'

To add a new proxy, without altering any of the existing ones, use

    % git config core.gitproxy '"proxy-command" for example.com'

An example to use customized color from the configuration in your script:

    #!/bin/sh
    WS=$(git config --get-color color.diff.whitespace "blue reverse")
    RESET=$(git config --get-color "" "reset")
    echo "${WS}your whitespace color or blue reverse${RESET}"

## CONFIGURATION FILE

The git configuration file contains a number of variables that affect the git command’s behavior. The `.git/config` file in each repository is used to store the configuration for that repository, and `$HOME/.gitconfig` is used to store a per-user configuration as fallback values for the `.git/config` file. The file `/etc/gitconfig` can be used to store a system-wide default configuration.

The configuration variables are used by both the git plumbing and the porcelains. The variables are divided into sections, wherein the fully qualified variable name of the variable itself is the last dot-separated segment and the section name is everything before the last dot. The variable names are case-insensitive and only alphanumeric characters are allowed. Some variables may appear multiple times.

### Syntax

The syntax is fairly flexible and permissive; whitespaces are mostly ignored. The # and ; characters begin comments to the end of line, blank lines are ignored.

The file consists of sections and variables. A section begins with the name of the section in square brackets and continues until the next section begins. Section names are not case sensitive. Only alphanumeric characters, `-` and `.` are allowed in section names. Each variable must belong to some section, which means that there must be a section header before the first setting of a variable.

Sections can be further divided into subsections. To begin a subsection put its name in double quotes, separated by space from the section name, in the section header, like in the example below:

            [section "subsection"]

Subsection names are case sensitive and can contain any characters except newline (doublequote `"` and backslash have to be escaped as `\"` and `\\`, respectively). Section headers cannot span multiple lines. Variables may belong directly to a section or to a given subsection. You can have `[section]` if you have `[section "subsection"]`, but you don’t need to.

There is also a case insensitive alternative `[section.subsection]` syntax. In this syntax, subsection names follow the same restrictions as for section names.

All the other lines (and the remainder of the line after the section header) are recognized as setting variables, in the form name = value. If there is no equal sign on the line, the entire line is taken as name and the variable is recognized as boolean "true". The variable names are case-insensitive and only alphanumeric characters and `-` are allowed. There can be more than one value for a given variable; we say then that variable is multivalued.

Leading and trailing whitespace in a variable value is discarded. Internal whitespace within a variable value is retained verbatim.

The values following the equals sign in variable assign are all either a string, an integer, or a boolean. Boolean values may be given as yes/no, 0/1, true/false or on/off. Case is not significant in boolean values, when converting value to the canonical form using --bool type specifier; git config will ensure that the output is "true" or "false".

String values may be entirely or partially enclosed in double quotes. You need to enclose variable values in double quotes if you want to preserve leading or trailing whitespace, or if the variable value contains comment characters (i.e. it contains # or ;). Double quote `"` and backslash `\` characters in variable values must be escaped: use `\"` for `"` and `\\` for `\`.

The following escape sequences (beside `\"` and `\\`) are recognized: `\n` for newline character (NL), `\t` for horizontal tabulation (HT, TAB) and `\b` for backspace (BS). No other char escape sequence, nor octal char sequences are valid.

Variable values ending in a `\` are continued on the next line in the customary UNIX fashion.

Some variables may require a special value format.

### Example

    # Core variables
    [core]
            ; Don't trust file modes
            filemode = false

    # Our diff algorithm
    [diff]
            external = /usr/local/bin/diff-wrapper
            renames = true

    [branch "devel"]
            remote = origin
            merge = refs/heads/devel

    # Proxy settings
    [core]
            gitProxy="ssh" for "kernel.org"
            gitProxy=default-proxy ; for the rest

### Variables

Note that this list is non-comprehensive and not necessarily complete. For command-specific variables, you will find a more detailed description in the appropriate manual page. You will find a description of non-core porcelain configuration variables in the respective porcelain documentation.

advice.*

  When set to true, display the given optional help message. When set to false, do not display. The configuration variables are:

  pushNonFastForward

    Advice shown when git-push(1) refuses non-fast-forward refs. Default: true.

  statusHints

    Directions on how to stage/unstage/add shown in the output of git-status(1) and the template shown when writing commit messages. Default: true.

  commitBeforeMerge

    Advice shown when git-merge(1) refuses to merge to avoid overwriting local changes. Default: true.

  resolveConflict

    Advices shown by various commands when conflicts prevent the operation from being performed. Default: true.

  implicitIdentity

    Advice on how to set your identity configuration when your information is guessed from the system username and domain name. Default: true.

  detachedHead

    Advice shown when you used :git-checkout(1) to move to the detach HEAD state, to instruct how to create a local branch after the fact. Default: true.

core.fileMode

  If false, the executable bit differences between the index and the working copy are ignored; useful on broken filesystems like FAT. See git-update-index(1).

  The default is true, except git-clone(1) or git-init(1) will probe and set core.fileMode false if appropriate when the repository is created.

core.ignoreCygwinFSTricks

  This option is only used by Cygwin implementation of Git. If false, the Cygwin stat() and lstat() functions are used. This may be useful if your repository consists of a few separate directories joined in one hierarchy using Cygwin mount. If true, Git uses native Win32 API whenever it is possible and falls back to Cygwin functions only to handle symbol links. The native mode is more than twice faster than normal Cygwin l/stat() functions. True by default, unless core.filemode is true, in which case ignoreCygwinFSTricks is ignored as Cygwin’s POSIX emulation is required to support core.filemode.

core.ignorecase

  If true, this option enables various workarounds to enable git to work better on filesystems that are not case sensitive, like FAT. For example, if a directory listing finds "makefile" when git expects "Makefile", git will assume it is really the same file, and continue to remember it as "Makefile".

  The default is false, except git-clone(1) or git-init(1) will probe and set core.ignorecase true if appropriate when the repository is created.

core.trustctime

  If false, the ctime differences between the index and the working copy are ignored; useful when the inode change time is regularly modified by something outside Git (file system crawlers and some backup systems). See git-update-index(1). True by default.

core.quotepath

  The commands that output paths (e.g. ls-files, diff), when not given the `-z` option, will quote "unusual" characters in the pathname by enclosing the pathname in a double-quote pair and with backslashes the same way strings in C source code are quoted. If this variable is set to false, the bytes higher than 0x80 are not quoted but output as verbatim. Note that double quote, backslash and control characters are always quoted without `-z` regardless of the setting of this variable.

core.eol

  Sets the line ending type to use in the working directory for files that have the `text` property set. Alternatives are lf, crlf and native, which uses the platform’s native line ending. The default value is `native`. See gitattributes(5) for more information on end-of-line conversion.

core.safecrlf

  If true, makes git check if converting `CRLF` is reversible when end-of-line conversion is active. Git will verify if a command modifies a file in the work tree either directly or indirectly. For example, committing a file followed by checking out the same file should yield the original file in the work tree. If this is not the case for the current setting of `core.autocrlf`, git will reject the file. The variable can be set to "warn", in which case git will only warn about an irreversible conversion but continue the operation.

  CRLF conversion bears a slight chance of corrupting data. When it is enabled, git will convert CRLF to LF during commit and LF to CRLF during checkout. A file that contains a mixture of LF and CRLF before the commit cannot be recreated by git. For text files this is the right thing to do: it corrects line endings such that we have only LF line endings in the repository. But for binary files that are accidentally classified as text the conversion can corrupt data.

  If you recognize such corruption early you can easily fix it by setting the conversion type explicitly in .gitattributes. Right after committing you still have the original file in your work tree and this file is not yet corrupted. You can explicitly tell git that this file is binary and git will handle the file appropriately.

  Unfortunately, the desired effect of cleaning up text files with mixed line endings and the undesired effect of corrupting binary files cannot be distinguished. In both cases CRLFs are removed in an irreversible way. For text files this is the right thing to do because CRLFs are line endings, while for binary files converting CRLFs corrupts data.

  Note, this safety check does not mean that a checkout will generate a file identical to the original file for a different setting of `core.eol` and `core.autocrlf`, but only for the current one. For example, a text file with `LF` would be accepted with `core.eol=lf` and could later be checked out with `core.eol=crlf`, in which case the resulting file would contain `CRLF`, although the original file contained `LF`. However, in both work trees the line endings would be consistent, that is either all `LF` or all `CRLF`, but never mixed. A file with mixed line endings would be reported by the `core.safecrlf` mechanism.

core.autocrlf

  Setting this variable to "true" is almost the same as setting the `text` attribute to "auto" on all files except that text files are not guaranteed to be normalized: files that contain `CRLF` in the repository will not be touched. Use this setting if you want to have `CRLF` line endings in your working directory even though the repository does not have normalized line endings. This variable can be set to input, in which case no output conversion is performed.

core.symlinks

  If false, symbolic links are checked out as small plain files that contain the link text. git-update-index(1) and git-add(1) will not change the recorded type to regular file. Useful on filesystems like FAT that do not support symbolic links.

  The default is true, except git-clone(1) or git-init(1) will probe and set core.symlinks false if appropriate when the repository is created.

core.gitProxy

  A "proxy command" to execute (as command host port) instead of establishing direct connection to the remote server when using the git protocol for fetching. If the variable value is in the "COMMAND for DOMAIN" format, the command is applied only on hostnames ending with the specified domain string. This variable may be set multiple times and is matched in the given order; the first match wins.

  Can be overridden by the GIT_PROXY_COMMAND environment variable (which always applies universally, without the special "for" handling).

  The special string `none` can be used as the proxy command to specify that no proxy be used for a given domain pattern. This is useful for excluding servers inside a firewall from proxy use, while defaulting to a common proxy for external domains.

core.ignoreStat

  If true, commands which modify both the working tree and the index will mark the updated paths with the "assume unchanged" bit in the index. These marked files are then assumed to stay unchanged in the working copy, until you mark them otherwise manually - Git will not detect the file changes by lstat() calls. This is useful on systems where those are very slow, such as Microsoft Windows. See git-update-index(1). False by default.

core.preferSymlinkRefs

  Instead of the default "symref" format for HEAD and other symbolic reference files, use symbolic links. This is sometimes needed to work with old scripts that expect HEAD to be a symbolic link.

core.bare

  If true this repository is assumed to be bare and has no working directory associated with it. If this is the case a number of commands that require a working directory will be disabled, such as git-add(1) or git-merge(1).

  This setting is automatically guessed by git-clone(1) or git-init(1) when the repository was created. By default a repository that ends in "/.git" is assumed to be not bare (bare = false), while all other repositories are assumed to be bare (bare = true).

core.worktree

  Set the path to the root of the working tree. This can be overridden by the GIT_WORK_TREE environment variable and the --work-tree command line option. The value can an absolute path or relative to the path to the .git directory, which is either specified by --git-dir or GIT_DIR, or automatically discovered. If --git-dir or GIT_DIR is specified but none of --work-tree, GIT_WORK_TREE and core.worktree is specified, the current working directory is regarded as the top level of your working tree.

  Note that this variable is honored even when set in a configuration file in a ".git" subdirectory of a directory and its value differs from the latter directory (e.g. "/path/to/.git/config" has core.worktree set to "/different/path"), which is most likely a misconfiguration. Running git commands in the "/path/to" directory will still use "/different/path" as the root of the work tree and can cause confusion unless you know what you are doing (e.g. you are creating a read-only snapshot of the same index to a location different from the repository’s usual working tree).

core.logAllRefUpdates

  Enable the reflog. Updates to a ref <ref> is logged to the file "$GIT_DIR/logs/<ref>", by appending the new and old SHA1, the date/time and the reason of the update, but only when the file exists. If this configuration variable is set to true, missing "$GIT_DIR/logs/<ref>" file is automatically created for branch heads.

  This information can be used to determine what commit was the tip of a branch "2 days ago".

  This value is true by default in a repository that has a working directory associated with it, and false by default in a bare repository.

core.repositoryFormatVersion

  Internal variable identifying the repository format and layout version.

core.sharedRepository

  When group (or true), the repository is made shareable between several users in a group (making sure all the files and objects are group-writable). When all (or world or everybody), the repository will be readable by all users, additionally to being group-shareable. When umask (or false), git will use permissions reported by umask(2). When 0xxx, where 0xxx is an octal number, files in the repository will have this mode value. 0xxx will override user’s umask value (whereas the other options will only override requested parts of the user’s umask value). Examples: 0660 will make the repo read/write-able for the owner and group, but inaccessible to others (equivalent to group unless umask is e.g. 0022). 0640 is a repository that is group-readable but not group-writable. See git-init(1). False by default.

core.warnAmbiguousRefs

  If true, git will warn you if the ref name you passed it is ambiguous and might match multiple refs in the .git/refs/ tree. True by default.

core.abbrevguard

  Even though git makes sure that it uses enough hexdigits to show an abbreviated object name unambiguously, as more objects are added to the repository over time, a short name that used to be unique will stop being unique. Git uses this many extra hexdigits that are more than necessary to make the object name currently unique, in the hope that its output will stay unique a bit longer. Defaults to 0.

core.compression

  An integer -1..9, indicating a default compression level. -1 is the zlib default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If set, this provides a default to other compression variables, such as core.loosecompression and pack.compression.

core.loosecompression

  An integer -1..9, indicating the compression level for objects that are not in a pack file. -1 is the zlib default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If not set, defaults to core.compression. If that is not set, defaults to 1 (best speed).

core.packedGitWindowSize

  Number of bytes of a pack file to map into memory in a single mapping operation. Larger window sizes may allow your system to process a smaller number of large pack files more quickly. Smaller window sizes will negatively affect performance due to increased calls to the operating system’s memory manager, but may improve performance when accessing a large number of large pack files.

  Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32 MiB on 32 bit platforms and 1 GiB on 64 bit platforms. This should be reasonable for all users/operating systems. You probably do not need to adjust this value.

  Common unit suffixes of k, m, or g are supported.

core.packedGitLimit

  Maximum number of bytes to map simultaneously into memory from pack files. If Git needs to access more than this many bytes at once to complete an operation it will unmap existing regions to reclaim virtual address space within the process.

  Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms. This should be reasonable for all users/operating systems, except on the largest projects. You probably do not need to adjust this value.

  Common unit suffixes of k, m, or g are supported.

core.deltaBaseCacheLimit

  Maximum number of bytes to reserve for caching base objects that may be referenced by multiple deltified objects. By storing the entire decompressed base objects in a cache Git is able to avoid unpacking and decompressing frequently used base objects multiple times.

  Default is 16 MiB on all platforms. This should be reasonable for all users/operating systems, except on the largest projects. You probably do not need to adjust this value.

  Common unit suffixes of k, m, or g are supported.

core.bigFileThreshold

  Files larger than this size are stored deflated, without attempting delta compression. Storing large files without delta compression avoids excessive memory usage, at the slight expense of increased disk usage.

  Default is 512 MiB on all platforms. This should be reasonable for most projects as source code and other text files can still be delta compressed, but larger binary media files won’t be.

  Common unit suffixes of k, m, or g are supported.

  Currently only git-fast-import(1) honors this setting.

core.excludesfile

  In addition to .gitignore (per-directory) and .git/info/exclude, git looks into this file for patterns of files which are not meant to be tracked. "~/" is expanded to the value of `$HOME` and "~user/" to the specified user’s home directory. See gitignore(5).

core.askpass

  Some commands (e.g. svn and http interfaces) that interactively ask for a password can be told to use an external program given via the value of this variable. Can be overridden by the GIT_ASKPASS environment variable. If not set, fall back to the value of the SSH_ASKPASS environment variable or, failing that, a simple password prompt. The external program shall be given a suitable prompt as command line argument and write the password on its STDOUT.

core.attributesfile

  In addition to .gitattributes (per-directory) and .git/info/attributes, git looks into this file for attributes (see gitattributes(5)). Path expansions are made the same way as for `core.excludesfile`.

core.editor

  Commands such as `commit` and `tag` that lets you edit messages by launching an editor uses the value of this variable when it is set, and the environment variable `GIT_EDITOR` is not set. See git-var(1).

core.pager

  The command that git will use to paginate output. Can be overridden with the `GIT_PAGER` environment variable. Note that git sets the `LESS` environment variable to `FRSX` if it is unset when it runs the pager. One can change these settings by setting the `LESS` variable to some other value. Alternately, these settings can be overridden on a project or global basis by setting the `core.pager` option. Setting `core.pager` has no affect on the `LESS` environment variable behaviour above, so if you want to override git’s default settings this way, you need to be explicit. For example, to disable the S option in a backward compatible manner, set `core.pager` to `less -+$LESS -FRX`. This will be passed to the shell by git, which will translate the final command to `LESS=FRSX less -+FRSX -FRX`.

core.whitespace

  A comma separated list of common whitespace problems to notice. git diff will use `color.diff.whitespace` to highlight them, and git apply --whitespace=error will consider them as errors. You can prefix `-` to disable any of them (e.g. `-trailing-space`):

  - `blank-at-eol` treats trailing whitespaces at the end of the line as an error (enabled by default).

  - `space-before-tab` treats a space character that appears immediately before a tab character in the initial indent part of the line as an error (enabled by default).

  - `indent-with-non-tab` treats a line that is indented with 8 or more space characters as an error (not enabled by default).

  - `tab-in-indent` treats a tab character in the initial indent part of the line as an error (not enabled by default).

  - `blank-at-eof` treats blank lines added at the end of file as an error (enabled by default).

  - `trailing-space` is a short-hand to cover both `blank-at-eol` and `blank-at-eof`.

  - `cr-at-eol` treats a carriage-return at the end of line as part of the line terminator, i.e. with it, `trailing-space` does not trigger if the character before such a carriage-return is not a whitespace (not enabled by default).

  - `tabwidth=<n>` tells how many character positions a tab occupies; this is relevant for `indent-with-non-tab` and when git fixes `tab-in-indent` errors. The default tab width is 8. Allowed values are 1 to 63.

core.fsyncobjectfiles

  This boolean will enable fsync() when writing object files.

  This is a total waste of time and effort on a filesystem that orders data writes properly, but can be useful for filesystems that do not use journalling (traditional UNIX filesystems) or that only journal metadata and not file contents (OS X’s HFS+, or Linux ext3 with "data=writeback").

core.preloadindex

  Enable parallel index preload for operations like git diff

  This can speed up operations like git diff and git status especially on filesystems like NFS that have weak caching semantics and thus relatively high IO latencies. With this set to true, git will do the index comparison to the filesystem data in parallel, allowing overlapping IO’s.

core.createObject

  You can set this to link, in which case a hardlink followed by a delete of the source are used to make sure that object creation will not overwrite existing objects.

  On some file system/operating system combinations, this is unreliable. Set this config setting to rename there; However, This will remove the check that makes sure that existing object files will not get overwritten.

core.notesRef

  When showing commit messages, also show notes which are stored in the given ref. The ref must be fully qualified. If the given ref does not exist, it is not an error but means that no notes should be printed.

  This setting defaults to "refs/notes/commits", and it can be overridden by the GIT_NOTES_REF environment variable. See git-notes(1).

core.sparseCheckout

  Enable "sparse checkout" feature. See section "Sparse checkout" in git-read-tree(1) for more information.

add.ignore-errors
add.ignoreErrors

  Tells git add to continue adding files when some files cannot be added due to indexing errors. Equivalent to the --ignore-errors option of git-add(1). Older versions of git accept only `add.ignore-errors`, which does not follow the usual naming convention for configuration variables. Newer versions of git honor `add.ignoreErrors` as well.

alias.*

  Command aliases for the git(1) command wrapper - e.g. after defining "alias.last = cat-file commit HEAD", the invocation "git last" is equivalent to "git cat-file commit HEAD". To avoid confusion and troubles with script usage, aliases that hide existing git commands are ignored. Arguments are split by spaces, the usual shell quoting and escaping is supported. quote pair and a backslash can be used to quote them.

  If the alias expansion is prefixed with an exclamation point, it will be treated as a shell command. For example, defining "alias.new = !gitk --all --not ORIG_HEAD", the invocation "git new" is equivalent to running the shell command "gitk --all --not ORIG_HEAD". Note that shell commands will be executed from the top-level directory of a repository, which may not necessarily be the current directory.

am.keepcr

  If true, git-am will call git-mailsplit for patches in mbox format with parameter --keep-cr. In this case git-mailsplit will not remove `\r` from lines ending with `\r\n`. Can be overridden by giving --no-keep-cr from the command line. See git-am(1), git-mailsplit(1).

apply.ignorewhitespace

  When set to change, tells git apply to ignore changes in whitespace, in the same way as the --ignore-space-change option. When set to one of: no, none, never, false tells git apply to respect all whitespace differences. See git-apply(1).

apply.whitespace

  Tells git apply how to handle whitespaces, in the same way as the --whitespace option. See git-apply(1).

branch.autosetupmerge

  Tells git branch and git checkout to set up new branches so that git-pull(1) will appropriately merge from the starting point branch. Note that even if this option is not set, this behavior can be chosen per-branch using the `--track` and `--no-track` options. The valid settings are: `false`— no automatic setup is done; `true`— automatic setup is done when the starting point is a remote-tracking branch; `always`—  automatic setup is done when the starting point is either a local branch or remote-tracking branch. This option defaults to true.

branch.autosetuprebase

  When a new branch is created with git branch or git checkout that tracks another branch, this variable tells git to set up pull to rebase instead of merge (see "branch.<name>.rebase"). When `never`, rebase is never automatically set to true. When `local`, rebase is set to true for tracked branches of other local branches. When `remote`, rebase is set to true for tracked branches of remote-tracking branches. When `always`, rebase will be set to true for all tracking branches. See "branch.autosetupmerge" for details on how to set up a branch to track another branch. This option defaults to never.

branch.<name>.remote

  When in branch <name>, it tells git fetch and git push which remote to fetch from/push to. It defaults to `origin` if no remote is configured. `origin` is also used if you are not on any branch.

branch.<name>.merge

  Defines, together with branch.<name>.remote, the upstream branch for the given branch. It tells git fetch/git pull which branch to merge and can also affect git push (see push.default). When in branch <name>, it tells git fetch the default refspec to be marked for merging in FETCH_HEAD. The value is handled like the remote part of a refspec, and must match a ref which is fetched from the remote given by "branch.<name>.remote". The merge information is used by git pull (which at first calls git fetch) to lookup the default branch for merging. Without this option, git pull defaults to merge the first refspec fetched. Specify multiple values to get an octopus merge. If you wish to setup git pull so that it merges into <name> from another branch in the local repository, you can point branch.<name>.merge to the desired branch, and use the special setting `.` (a period) for branch.<name>.remote.

branch.<name>.mergeoptions

  Sets default options for merging into branch <name>. The syntax and supported options are the same as those of git-merge(1), but option values containing whitespace characters are currently not supported.

branch.<name>.rebase

  When true, rebase the branch <name> on top of the fetched branch, instead of merging the default branch from the default remote when "git pull" is run. NOTE: this is a possibly dangerous operation; do not use it unless you understand the implications (see git-rebase(1) for details).

browser.<tool>.cmd

  Specify the command to invoke the specified browser. The specified command is evaluated in shell with the URLs passed as arguments. (See git-web—browse(1).)

browser.<tool>.path

  Override the path for the given tool that may be used to browse HTML help (see -w option in git-help(1)) or a working repository in gitweb (see git-instaweb(1)).

clean.requireForce

  A boolean to make git-clean do nothing unless given -f or -n. Defaults to true.

color.branch

  A boolean to enable/disable color in the output of git-branch(1). May be set to `always`, `false` (or `never`) or `auto` (or `true`), in which case colors are used only when the output is to a terminal. Defaults to false.

color.branch.<slot>

  Use customized color for branch coloration. `<slot>` is one of `current` (the current branch), `local` (a local branch), `remote` (a remote-tracking branch in refs/remotes/), `plain` (other refs).

  The value for these configuration variables is a list of colors (at most two) and attributes (at most one), separated by spaces. The colors accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`, `magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`, `blink` and `reverse`. The first color given is the foreground; the second is the background. The position of the attribute, if any, doesn’t matter.

color.diff

  When set to `always`, always use colors in patch. When false (or `never`), never. When set to `true` or `auto`, use colors only when the output is to the terminal. Defaults to false.

color.diff.<slot>

  Use customized color for diff colorization. `<slot>` specifies which part of the patch to use the specified color, and is one of `plain` (context text), `meta` (metainformation), `frag` (hunk header), func (function in hunk header), `old` (removed lines), `new` (added lines), `commit` (commit headers), or `whitespace` (highlighting whitespace errors). The values of these variables may be specified as in color.branch.<slot>.

color.decorate.<slot>

  Use customized color for git log --decorate output. `<slot>` is one of `branch`, `remoteBranch`, `tag`, `stash` or `HEAD` for local branches, remote-tracking branches, tags, stash and HEAD, respectively.

color.grep

  When set to `always`, always highlight matches. When `false` (or `never`), never. When set to `true` or `auto`, use color only when the output is written to the terminal. Defaults to `false`.

color.grep.<slot>

  Use customized color for grep colorization. `<slot>` specifies which part of the line to use the specified color, and is one of

  `context`

    non-matching text in context lines (when using `-A`, `-B`, or `-C`)

  `filename`

    filename prefix (when not using `-h`)

  `function`

    function name lines (when using `-p`)

  `linenumber`

    line number prefix (when using `-n`)

  `match`

    matching text

  `selected`

    non-matching text in selected lines

  `separator`

    separators between fields on a line (`:`, `-`, and `=`) and between hunks (`--`)

  The values of these variables may be specified as in color.branch.<slot>.

color.interactive

  When set to `always`, always use colors for interactive prompts and displays (such as those used by "git-add --interactive"). When false (or `never`), never. When set to `true` or `auto`, use colors only when the output is to the terminal. Defaults to false.

color.interactive.<slot>

  Use customized color for git add --interactive output. `<slot>` may be `prompt`, `header`, `help` or `error`, for four distinct types of normal output from interactive commands. The values of these variables may be specified as in color.branch.<slot>.

color.pager

  A boolean to enable/disable colored output when the pager is in use (default is true).

color.showbranch

  A boolean to enable/disable color in the output of git-show-branch(1). May be set to `always`, `false` (or `never`) or `auto` (or `true`), in which case colors are used only when the output is to a terminal. Defaults to false.

color.status

  A boolean to enable/disable color in the output of git-status(1). May be set to `always`, `false` (or `never`) or `auto` (or `true`), in which case colors are used only when the output is to a terminal. Defaults to false.

color.status.<slot>

  Use customized color for status colorization. `<slot>` is one of `header` (the header text of the status message), `added` or `updated` (files which are added but not committed), `changed` (files which are changed but not added in the index), `untracked` (files which are not tracked by git), `branch` (the current branch), or `nobranch` (the color the no branch warning is shown in, defaulting to red). The values of these variables may be specified as in color.branch.<slot>.

color.ui

  When set to `always`, always use colors in all git commands which are capable of colored output. When false (or `never`), never. When set to `true` or `auto`, use colors only when the output is to the terminal. When more specific variables of color.* are set, they always take precedence over this setting. Defaults to false.

commit.status

  A boolean to enable/disable inclusion of status information in the commit message template when using an editor to prepare the commit message. Defaults to true.

commit.template

  Specify a file to use as the template for new commit messages. "~/" is expanded to the value of `$HOME` and "~user/" to the specified user’s home directory.

diff.autorefreshindex

  When using git diff to compare with work tree files, do not consider stat-only change as changed. Instead, silently run `git update-index --refresh` to update the cached stat information for paths whose contents in the work tree match the contents in the index. This option defaults to true. Note that this affects only git diff Porcelain, and not lower level diff commands such as git diff-files.

diff.external

  If this config variable is set, diff generation is not performed using the internal diff machinery, but using the given command. Can be overridden with the ‘GIT_EXTERNAL_DIFF’ environment variable. The command is called with parameters as described under "git Diffs" in git(1). Note: if you want to use an external diff program only on a subset of your files, you might want to use gitattributes(5) instead.

diff.mnemonicprefix

  If set, git diff uses a prefix pair that is different from the standard "a/" and "b/" depending on what is being compared. When this configuration is in effect, reverse diff output also swaps the order of the prefixes:

  `git diff`

    compares the (i)ndex and the (w)ork tree;

  `git diff HEAD`

    compares a (c)ommit and the (w)ork tree;

  `git diff --cached`

    compares a (c)ommit and the (i)ndex;

  `git diff HEAD:file1 file2`

    compares an (o)bject and a (w)ork tree entity;

  `git diff --no-index a b`

    compares two non-git things (1) and (2).

diff.noprefix

  If set, git diff does not show any source or destination prefix.

diff.renameLimit

  The number of files to consider when performing the copy/rename detection; equivalent to the git diff option -l.

diff.renames

  Tells git to detect renames. If set to any boolean value, it will enable basic rename detection. If set to "copies" or "copy", it will detect copies, as well.

diff.ignoreSubmodules

  Sets the default value of --ignore-submodules. Note that this affects only git diff Porcelain, and not lower level diff commands such as git diff-files. git checkout also honors this setting when reporting uncommitted changes.

diff.suppressBlankEmpty

  A boolean to inhibit the standard behavior of printing a space before each empty output line. Defaults to false.

diff.tool

  Controls which diff tool is used. `diff.tool` overrides `merge.tool` when used by git-difftool(1) and has the same valid values as `merge.tool` minus "tortoisemerge" and plus "kompare".

difftool.<tool>.path

  Override the path for the given tool. This is useful in case your tool is not in the PATH.

difftool.<tool>.cmd

  Specify the command to invoke the specified diff tool. The specified command is evaluated in shell with the following variables available: LOCAL is set to the name of the temporary file containing the contents of the diff pre-image and REMOTE is set to the name of the temporary file containing the contents of the diff post-image.

difftool.prompt

  Prompt before each invocation of the diff tool.

diff.wordRegex

  A POSIX Extended Regular Expression used to determine what is a "word" when performing word-by-word difference calculations. Character sequences that match the regular expression are "words", all other characters are ignorable whitespace.

fetch.recurseSubmodules

  A boolean value which changes the behavior for fetch and pull, the default is to not recursively fetch populated submodules unless configured otherwise.

fetch.unpackLimit

  If the number of objects fetched over the git native transfer is below this limit, then the objects will be unpacked into loose object files. However if the number of received objects equals or exceeds this limit then the received pack will be stored as a pack, after adding any missing delta bases. Storing the pack from a push can make the push operation complete faster, especially on slow filesystems. If not set, the value of `transfer.unpackLimit` is used instead.

format.attach

  Enable multipart/mixed attachments as the default for format-patch. The value can also be a double quoted string which will enable attachments as the default and set the value as the boundary. See the --attach option in git-format-patch(1).

format.numbered

  A boolean which can enable or disable sequence numbers in patch subjects. It defaults to "auto" which enables it only if there is more than one patch. It can be enabled or disabled for all messages by setting it to "true" or "false". See --numbered option in git-format-patch(1).

format.headers

  Additional email headers to include in a patch to be submitted by mail. See git-format-patch(1).

format.to
format.cc

  Additional recipients to include in a patch to be submitted by mail. See the --to and --cc options in git-format-patch(1).

format.subjectprefix

  The default for format-patch is to output files with the [PATCH] subject prefix. Use this variable to change that prefix.

format.signature

  The default for format-patch is to output a signature containing the git version number. Use this variable to change that default. Set this variable to the empty string ("") to suppress signature generation.

format.suffix

  The default for format-patch is to output files with the suffix `.patch`. Use this variable to change that suffix (make sure to include the dot if you want it).

format.pretty

  The default pretty format for log/show/whatchanged command, See git-log(1), git-show(1), git-whatchanged(1).

format.thread

  The default threading style for git format-patch. Can be a boolean value, or `shallow` or `deep`. `shallow` threading makes every mail a reply to the head of the series, where the head is chosen from the cover letter, the `--in-reply-to`, and the first patch mail, in this order. `deep` threading makes every mail a reply to the previous one. A true boolean value is the same as `shallow`, and a false value disables threading.

format.signoff

  A boolean value which lets you enable the `-s/--signoff` option of format-patch by default. Note: Adding the Signed-off-by: line to a patch should be a conscious act and means that you certify you have the rights to submit this work under the same open source license. Please see the SubmittingPatches document for further discussion.

gc.aggressiveWindow

  The window size parameter used in the delta compression algorithm used by git gc --aggressive. This defaults to 250.

gc.auto

  When there are approximately more than this many loose objects in the repository, `git gc --auto` will pack them. Some Porcelain commands use this command to perform a light-weight garbage collection from time to time. The default value is 6700. Setting this to 0 disables it.

gc.autopacklimit

  When there are more than this many packs that are not marked with `*.keep` file in the repository, `git gc --auto` consolidates them into one larger pack. The default value is 50. Setting this to 0 disables it.

gc.packrefs

  Running `git pack-refs` in a repository renders it unclonable by Git versions prior to 1.5.1.2 over dumb transports such as HTTP. This variable determines whether git gc runs `git pack-refs`. This can be set to `notbare` to enable it within all non-bare repos or it can be set to a boolean value. The default is `true`.

gc.pruneexpire

  When git gc is run, it will call prune --expire 2.weeks.ago. Override the grace period with this config variable. The value "now" may be used to disable this grace period and always prune unreachable objects immediately.

gc.reflogexpire
gc.<pattern>.reflogexpire

  git reflog expire removes reflog entries older than this time; defaults to 90 days. With "<pattern>" (e.g. "refs/stash") in the middle the setting applies only to the refs that match the <pattern>.

gc.reflogexpireunreachable
gc.<ref>.reflogexpireunreachable

  git reflog expire removes reflog entries older than this time and are not reachable from the current tip; defaults to 30 days. With "<pattern>" (e.g. "refs/stash") in the middle, the setting applies only to the refs that match the <pattern>.

gc.rerereresolved

  Records of conflicted merge you resolved earlier are kept for this many days when git rerere gc is run. The default is 60 days. See git-rerere(1).

gc.rerereunresolved

  Records of conflicted merge you have not resolved are kept for this many days when git rerere gc is run. The default is 15 days. See git-rerere(1).

gitcvs.commitmsgannotation

  Append this string to each commit message. Set to empty string to disable this feature. Defaults to "via git-CVS emulator".

gitcvs.enabled

  Whether the CVS server interface is enabled for this repository. See git-cvsserver(1).

gitcvs.logfile

  Path to a log file where the CVS server interface well… logs various stuff. See git-cvsserver(1).

gitcvs.usecrlfattr

  If true, the server will look up the end-of-line conversion attributes for files to determine the -k modes to use. If the attributes force git to treat a file as text, the -k mode will be left blank so CVS clients will treat it as text. If they suppress text conversion, the file will be set with -kb mode, which suppresses any newline munging the client might otherwise do. If the attributes do not allow the file type to be determined, then gitcvs.allbinary is used. See gitattributes(5).

gitcvs.allbinary

  This is used if gitcvs.usecrlfattr does not resolve the correct -kb mode to use. If true, all unresolved files are sent to the client in mode -kb. This causes the client to treat them as binary files, which suppresses any newline munging it otherwise might do. Alternatively, if it is set to "guess", then the contents of the file are examined to decide if it is binary, similar to core.autocrlf.

gitcvs.dbname

  Database used by git-cvsserver to cache revision information derived from the git repository. The exact meaning depends on the used database driver, for SQLite (which is the default driver) this is a filename. Supports variable substitution (see git-cvsserver(1) for details). May not contain semicolons (`;`). Default: %Ggitcvs.%m.sqlite

gitcvs.dbdriver

  Used Perl DBI driver. You can specify any available driver for this here, but it might not work. git-cvsserver is tested with DBD::SQLite, reported to work with DBD::Pg, and reported not to work with DBD::mysql. Experimental feature. May not contain double colons (`:`). Default: SQLite. See git-cvsserver(1).

gitcvs.dbuser, gitcvs.dbpass

  Database user and password. Only useful if setting gitcvs.dbdriver, since SQLite has no concept of database users and/or passwords. gitcvs.dbuser supports variable substitution (see git-cvsserver(1) for details).

gitcvs.dbTableNamePrefix

  Database table name prefix. Prepended to the names of any database tables used, allowing a single database to be used for several repositories. Supports variable substitution (see git-cvsserver(1) for details). Any non-alphabetic characters will be replaced with underscores.

All gitcvs variables except for gitcvs.usecrlfattr and gitcvs.allbinary can also be specified as gitcvs.<access_method>.<varname> (where access_method is one of "ext" and "pserver") to make them apply only for the given access method.

gui.commitmsgwidth

  Defines how wide the commit message window is in the git-gui(1). "75" is the default.

gui.diffcontext

  Specifies how many context lines should be used in calls to diff made by the git-gui(1). The default is "5".

gui.encoding

  Specifies the default encoding to use for displaying of file contents in git-gui(1) and gitk(1). It can be overridden by setting the encoding attribute for relevant files (see gitattributes(5)). If this option is not set, the tools default to the locale encoding.

gui.matchtrackingbranch

  Determines if new branches created with git-gui(1) should default to tracking remote branches with matching names or not. Default: "false".

gui.newbranchtemplate

  Is used as suggested name when creating new branches using the git-gui(1).

gui.pruneduringfetch

  "true" if git-gui(1) should prune remote-tracking branches when performing a fetch. The default value is "false".

gui.trustmtime

  Determines if git-gui(1) should trust the file modification timestamp or not. By default the timestamps are not trusted.

gui.spellingdictionary

  Specifies the dictionary used for spell checking commit messages in the git-gui(1). When set to "none" spell checking is turned off.

gui.fastcopyblame

  If true, git gui blame uses `-C` instead of `-C -C` for original location detection. It makes blame significantly faster on huge repositories at the expense of less thorough copy detection.

gui.copyblamethreshold

  Specifies the threshold to use in git gui blame original location detection, measured in alphanumeric characters. See the git-blame(1) manual for more information on copy detection.

gui.blamehistoryctx

  Specifies the radius of history context in days to show in gitk(1) for the selected commit, when the `Show History Context` menu item is invoked from git gui blame. If this variable is set to zero, the whole history is shown.

guitool.<name>.cmd

  Specifies the shell command line to execute when the corresponding item of the git-gui(1) `Tools` menu is invoked. This option is mandatory for every tool. The command is executed from the root of the working directory, and in the environment it receives the name of the tool as GIT_GUITOOL, the name of the currently selected file as FILENAME, and the name of the current branch as CUR_BRANCH (if the head is detached, CUR_BRANCH is empty).

guitool.<name>.needsfile

  Run the tool only if a diff is selected in the GUI. It guarantees that FILENAME is not empty.

guitool.<name>.noconsole

  Run the command silently, without creating a window to display its output.

guitool.<name>.norescan

  Don’t rescan the working directory for changes after the tool finishes execution.

guitool.<name>.confirm

  Show a confirmation dialog before actually running the tool.

guitool.<name>.argprompt

  Request a string argument from the user, and pass it to the tool through the ARGS environment variable. Since requesting an argument implies confirmation, the confirm option has no effect if this is enabled. If the option is set to true, yes, or 1, the dialog uses a built-in generic prompt; otherwise the exact value of the variable is used.

guitool.<name>.revprompt

  Request a single valid revision from the user, and set the REVISION environment variable. In other aspects this option is similar to argprompt, and can be used together with it.

guitool.<name>.revunmerged

  Show only unmerged branches in the revprompt subdialog. This is useful for tools similar to merge or rebase, but not for things like checkout or reset.

guitool.<name>.title

  Specifies the title to use for the prompt dialog. The default is the tool name.

guitool.<name>.prompt

  Specifies the general prompt string to display at the top of the dialog, before subsections for argprompt and revprompt. The default value includes the actual command.

help.browser

  Specify the browser that will be used to display help in the web format. See git-help(1).

help.format

  Override the default help format used by git-help(1). Values man, info, web and html are supported. man is the default. web and html are the same.

help.autocorrect

  Automatically correct and execute mistyped commands after waiting for the given number of deciseconds (0.1 sec). If more than one command can be deduced from the entered text, nothing will be executed. If the value of this option is negative, the corrected command will be executed immediately. If the value is 0 - the command will be just shown but not executed. This is the default.

http.proxy

  Override the HTTP proxy, normally configured using the http_proxy environment variable (see curl(1)). This can be overridden on a per-remote basis; see remote.<name>.proxy

http.sslVerify

  Whether to verify the SSL certificate when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_NO_VERIFY environment variable.

http.sslCert

  File containing the SSL certificate when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_CERT environment variable.

http.sslKey

  File containing the SSL private key when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_KEY environment variable.

http.sslCertPasswordProtected

  Enable git’s password prompt for the SSL certificate. Otherwise OpenSSL will prompt the user, possibly many times, if the certificate or private key is encrypted. Can be overridden by the GIT_SSL_CERT_PASSWORD_PROTECTED environment variable.

http.sslCAInfo

  File containing the certificates to verify the peer with when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_CAINFO environment variable.

http.sslCAPath

  Path containing files with the CA certificates to verify the peer with when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_CAPATH environment variable.

http.maxRequests

  How many HTTP requests to launch in parallel. Can be overridden by the GIT_HTTP_MAX_REQUESTS environment variable. Default is 5.

http.minSessions

  The number of curl sessions (counted across slots) to be kept across requests. They will not be ended with curl_easy_cleanup() until http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this value will be capped at 1. Defaults to 1.

http.postBuffer

  Maximum size in bytes of the buffer used by smart HTTP transports when POSTing data to the remote system. For requests larger than this buffer size, HTTP/1.1 and Transfer-Encoding: chunked is used to avoid creating a massive pack file locally. Default is 1 MiB, which is sufficient for most requests.

http.lowSpeedLimit, http.lowSpeedTime

  If the HTTP transfer speed is less than http.lowSpeedLimit for longer than http.lowSpeedTime seconds, the transfer is aborted. Can be overridden by the GIT_HTTP_LOW_SPEED_LIMIT and GIT_HTTP_LOW_SPEED_TIME environment variables.

http.noEPSV

  A boolean which disables using of EPSV ftp command by curl. This can helpful with some "poor" ftp servers which don’t support EPSV mode. Can be overridden by the GIT_CURL_FTP_NO_EPSV environment variable. Default is false (curl will use EPSV).

http.useragent

  The HTTP USER_AGENT string presented to an HTTP server. The default value represents the version of the client git such as git/1.7.1. This option allows you to override this value to a more common value such as Mozilla/4.0. This may be necessary, for instance, if connecting through a firewall that restricts HTTP connections to a set of common USER_AGENT strings (but not including those like git/1.7.1). Can be overridden by the GIT_HTTP_USER_AGENT environment variable.

i18n.commitEncoding

  Character encoding the commit messages are stored in; git itself does not care per se, but this information is necessary e.g. when importing commits from emails or in the gitk graphical history browser (and possibly at other places in the future or in other porcelains). See e.g. git-mailinfo(1). Defaults to utf-8.

i18n.logOutputEncoding

  Character encoding the commit messages are converted to when running git log and friends.

imap

  The configuration variables in the imap section are described in git-imap-send(1).

init.templatedir

  Specify the directory from which templates will be copied. (See the "TEMPLATE DIRECTORY" section of git-init(1).)

instaweb.browser

  Specify the program that will be used to browse your working repository in gitweb. See git-instaweb(1).

instaweb.httpd

  The HTTP daemon command-line to start gitweb on your working repository. See git-instaweb(1).

instaweb.local

  If true the web server started by git-instaweb(1) will be bound to the local IP (127.0.0.1).

instaweb.modulepath

  The default module path for git-instaweb(1) to use instead of /usr/lib/apache2/modules. Only used if httpd is Apache.

instaweb.port

  The port number to bind the gitweb httpd to. See git-instaweb(1).

interactive.singlekey

  In interactive commands, allow the user to provide one-letter input with a single key (i.e., without hitting enter). Currently this is used only by the `--patch` mode of git-add(1). Note that this setting is silently ignored if portable keystroke input is not available.

log.date

  Set the default date-time mode for the log command. Setting a value for log.date is similar to using git log's `--date` option. Possible values are `relative`, `local`, `default`, `iso`, `rfc`, and `short`; see git-log(1) for details.

log.decorate

  Print out the ref names of any commits that are shown by the log command. If short is specified, the ref name prefixes refs/heads/, refs/tags/ and refs/remotes/ will not be printed. If full is specified, the full ref name (including prefix) will be printed. This is the same as the log commands --decorate option.

log.showroot

  If true, the initial commit will be shown as a big creation event. This is equivalent to a diff against an empty tree. Tools like git-log(1) or git-whatchanged(1), which normally hide the root commit will now show it. True by default.

mailmap.file

  The location of an augmenting mailmap file. The default mailmap, located in the root of the repository, is loaded first, then the mailmap file pointed to by this variable. The location of the mailmap file may be in a repository subdirectory, or somewhere outside of the repository itself. See git-shortlog(1) and git-blame(1).

man.viewer

  Specify the programs that may be used to display help in the man format. See git-help(1).

man.<tool>.cmd

  Specify the command to invoke the specified man viewer. The specified command is evaluated in shell with the man page passed as argument. (See git-help(1).)

man.<tool>.path

  Override the path for the given tool that may be used to display help in the man format. See git-help(1).

merge.conflictstyle

  Specify the style in which conflicted hunks are written out to working tree files upon merge. The default is "merge", which shows a `<<<<<<<` conflict marker, changes made by one side, a `=======` marker, changes made by the other side, and then a `>>>>>>>` marker. An alternate style, "diff3", adds a `|||||||` marker and the original text before the `=======` marker.

merge.log

  In addition to branch names, populate the log message with at most the specified number of one-line descriptions from the actual commits that are being merged. Defaults to false, and true is a synonym for 20.

merge.renameLimit

  The number of files to consider when performing rename detection during a merge; if not specified, defaults to the value of diff.renameLimit.

merge.renormalize

  Tell git that canonical representation of files in the repository has changed over time (e.g. earlier commits record text files with CRLF line endings, but recent ones use LF line endings). In such a repository, git can convert the data recorded in commits to a canonical form before performing a merge to reduce unnecessary conflicts. For more information, see section "Merging branches with differing checkin/checkout attributes" in gitattributes(5).

merge.stat

  Whether to print the diffstat between ORIG_HEAD and the merge result at the end of the merge. True by default.

merge.tool

  Controls which merge resolution program is used by git-mergetool(1). Valid built-in values are: "kdiff3", "tkdiff", "meld", "xxdiff", "emerge", "vimdiff", "gvimdiff", "diffuse", "ecmerge", "tortoisemerge", "p4merge", "araxis" and "opendiff". Any other value is treated is custom merge tool and there must be a corresponding mergetool.<tool>.cmd option.

merge.verbosity

  Controls the amount of output shown by the recursive merge strategy. Level 0 outputs nothing except a final error message if conflicts were detected. Level 1 outputs only conflicts, 2 outputs conflicts and file changes. Level 5 and above outputs debugging information. The default is level 2. Can be overridden by the GIT_MERGE_VERBOSITY environment variable.

merge.<driver>.name

  Defines a human-readable name for a custom low-level merge driver. See gitattributes(5) for details.

merge.<driver>.driver

  Defines the command that implements a custom low-level merge driver. See gitattributes(5) for details.

merge.<driver>.recursive

  Names a low-level merge driver to be used when performing an internal merge between common ancestors. See gitattributes(5) for details.

mergetool.<tool>.path

  Override the path for the given tool. This is useful in case your tool is not in the PATH.

mergetool.<tool>.cmd

  Specify the command to invoke the specified merge tool. The specified command is evaluated in shell with the following variables available: BASE is the name of a temporary file containing the common base of the files to be merged, if available; LOCAL is the name of a temporary file containing the contents of the file on the current branch; REMOTE is the name of a temporary file containing the contents of the file from the branch being merged; MERGED contains the name of the file to which the merge tool should write the results of a successful merge.

mergetool.<tool>.trustExitCode

  For a custom merge command, specify whether the exit code of the merge command can be used to determine whether the merge was successful. If this is not set to true then the merge target file timestamp is checked and the merge assumed to have been successful if the file has been updated, otherwise the user is prompted to indicate the success of the merge.

mergetool.keepBackup

  After performing a merge, the original file with conflict markers can be saved as a file with a `.orig` extension. If this variable is set to `false` then this file is not preserved. Defaults to `true` (i.e. keep the backup files).

mergetool.keepTemporaries

  When invoking a custom merge tool, git uses a set of temporary files to pass to the tool. If the tool returns an error and this variable is set to `true`, then these temporary files will be preserved, otherwise they will be removed after the tool has exited. Defaults to `false`.

mergetool.prompt

  Prompt before each invocation of the merge resolution program.

notes.displayRef

  The (fully qualified) refname from which to show notes when showing commit messages. The value of this variable can be set to a glob, in which case notes from all matching refs will be shown. You may also specify this configuration variable several times. A warning will be issued for refs that do not exist, but a glob that does not match any refs is silently ignored.

  This setting can be overridden with the `GIT_NOTES_DISPLAY_REF` environment variable, which must be a colon separated list of refs or globs.

  The effective value of "core.notesRef" (possibly overridden by GIT_NOTES_REF) is also implicitly added to the list of refs to be displayed.

notes.rewrite.<command>

  When rewriting commits with <command> (currently `amend` or `rebase`) and this variable is set to `true`, git automatically copies your notes from the original to the rewritten commit. Defaults to `true`, but see "notes.rewriteRef" below.

notes.rewriteMode

  When copying notes during a rewrite (see the "notes.rewrite.<command>" option), determines what to do if the target commit already has a note. Must be one of `overwrite`, `concatenate`, or `ignore`. Defaults to `concatenate`.

  This setting can be overridden with the `GIT_NOTES_REWRITE_MODE` environment variable.

notes.rewriteRef

  When copying notes during a rewrite, specifies the (fully qualified) ref whose notes should be copied. The ref may be a glob, in which case notes in all matching refs will be copied. You may also specify this configuration several times.

  Does not have a default value; you must configure this variable to enable note rewriting.

  This setting can be overridden with the `GIT_NOTES_REWRITE_REF` environment variable, which must be a colon separated list of refs or globs.

pack.window

  The size of the window used by git-pack-objects(1) when no window size is given on the command line. Defaults to 10.

pack.depth

  The maximum delta depth used by git-pack-objects(1) when no maximum depth is given on the command line. Defaults to 50.

pack.windowMemory

  The window memory size limit used by git-pack-objects(1) when no limit is given on the command line. The value can be suffixed with "k", "m", or "g". Defaults to 0, meaning no limit.

pack.compression

  An integer -1..9, indicating the compression level for objects in a pack file. -1 is the zlib default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If not set, defaults to core.compression. If that is not set, defaults to -1, the zlib default, which is "a default compromise between speed and compression (currently equivalent to level 6)."

  Note that changing the compression level will not automatically recompress all existing objects. You can force recompression by passing the -F option to git-repack(1).

pack.deltaCacheSize

  The maximum memory in bytes used for caching deltas in git-pack-objects(1) before writing them out to a pack. This cache is used to speed up the writing object phase by not having to recompute the final delta result once the best match for all objects is found. Repacking large repositories on machines which are tight with memory might be badly impacted by this though, especially if this cache pushes the system into swapping. A value of 0 means no limit. The smallest size of 1 byte may be used to virtually disable this cache. Defaults to 256 MiB.

pack.deltaCacheLimit

  The maximum size of a delta, that is cached in git-pack-objects(1). This cache is used to speed up the writing object phase by not having to recompute the final delta result once the best match for all objects is found. Defaults to 1000.

pack.threads

  Specifies the number of threads to spawn when searching for best delta matches. This requires that git-pack-objects(1) be compiled with pthreads otherwise this option is ignored with a warning. This is meant to reduce packing time on multiprocessor machines. The required amount of memory for the delta search window is however multiplied by the number of threads. Specifying 0 will cause git to auto-detect the number of CPU’s and set the number of threads accordingly.

pack.indexVersion

  Specify the default pack index version. Valid values are 1 for legacy pack index used by Git versions prior to 1.5.2, and 2 for the new pack index with capabilities for packs larger than 4 GB as well as proper protection against the repacking of corrupted packs. Version 2 is the default. Note that version 2 is enforced and this config option ignored whenever the corresponding pack is larger than 2 GB.

  If you have an old git that does not understand the version 2 `*.idx` file, cloning or fetching over a non native protocol (e.g. "http" and "rsync") that will copy both `*.pack` file and corresponding `*.idx` file from the other side may give you a repository that cannot be accessed with your older version of git. If the `*.pack` file is smaller than 2 GB, however, you can use git-index-pack(1) on the *.pack file to regenerate the `*.idx` file.

pack.packSizeLimit

  The maximum size of a pack. This setting only affects packing to a file when repacking, i.e. the git:// protocol is unaffected. It can be overridden by the `--max-pack-size` option of git-repack(1). The minimum size allowed is limited to 1 MiB. The default is unlimited. Common unit suffixes of k, m, or g are supported.

pager.<cmd>

  If the value is boolean, turns on or off pagination of the output of a particular git subcommand when writing to a tty. Otherwise, turns on pagination for the subcommand using the pager specified by the value of `pager.<cmd>`. If `--paginate` or `--no-pager` is specified on the command line, it takes precedence over this option. To disable pagination for all commands, set `core.pager` or `GIT_PAGER` to `cat`.

pretty.<name>

  Alias for a --pretty= format string, as specified in git-log(1). Any aliases defined here can be used just as the built-in pretty formats could. For example, running `git config pretty.changelog "format:* %H %s"` would cause the invocation `git log --pretty=changelog` to be equivalent to running `git log "--pretty=format:* %H %s"`. Note that an alias with the same name as a built-in format will be silently ignored.

pull.octopus

  The default merge strategy to use when pulling multiple branches at once.

pull.twohead

  The default merge strategy to use when pulling a single branch.

push.default

  Defines the action git push should take if no refspec is given on the command line, no refspec is configured in the remote, and no refspec is implied by any of the options given on the command line. Possible values are:

  - `nothing` - do not push anything.

  - `matching` - push all matching branches. All branches having the same name in both ends are considered to be matching. This is the default.

  - `tracking` - push the current branch to its upstream branch.

  - `current` - push the current branch to a branch of the same name.

rebase.stat

  Whether to show a diffstat of what changed upstream since the last rebase. False by default.

rebase.autosquash

  If set to true enable --autosquash option by default.

receive.autogc

  By default, git-receive-pack will run "git-gc --auto" after receiving data from git-push and updating refs. You can stop it by setting this variable to false.

receive.fsckObjects

  If it is set to true, git-receive-pack will check all received objects. It will abort in the case of a malformed object or a broken link. The result of an abort are only dangling objects. Defaults to false.

receive.unpackLimit

  If the number of objects received in a push is below this limit then the objects will be unpacked into loose object files. However if the number of received objects equals or exceeds this limit then the received pack will be stored as a pack, after adding any missing delta bases. Storing the pack from a push can make the push operation complete faster, especially on slow filesystems. If not set, the value of `transfer.unpackLimit` is used instead.

receive.denyDeletes

  If set to true, git-receive-pack will deny a ref update that deletes the ref. Use this to prevent such a ref deletion via a push.

receive.denyDeleteCurrent

  If set to true, git-receive-pack will deny a ref update that deletes the currently checked out branch of a non-bare repository.

receive.denyCurrentBranch

  If set to true or "refuse", git-receive-pack will deny a ref update to the currently checked out branch of a non-bare repository. Such a push is potentially dangerous because it brings the HEAD out of sync with the index and working tree. If set to "warn", print a warning of such a push to stderr, but allow the push to proceed. If set to false or "ignore", allow such pushes with no message. Defaults to "refuse".

receive.denyNonFastForwards

  If set to true, git-receive-pack will deny a ref update which is not a fast-forward. Use this to prevent such an update via a push, even if that push is forced. This configuration variable is set when initializing a shared repository.

receive.updateserverinfo

  If set to true, git-receive-pack will run git-update-server-info after receiving data from git-push and updating refs.

remote.<name>.url

  The URL of a remote repository. See git-fetch(1) or git-push(1).

remote.<name>.pushurl

  The push URL of a remote repository. See git-push(1).

remote.<name>.proxy

  For remotes that require curl (http, https and ftp), the URL to the proxy to use for that remote. Set to the empty string to disable proxying for that remote.

remote.<name>.fetch

  The default set of "refspec" for git-fetch(1). See git-fetch(1).

remote.<name>.push

  The default set of "refspec" for git-push(1). See git-push(1).

remote.<name>.mirror

  If true, pushing to this remote will automatically behave as if the `--mirror` option was given on the command line.

remote.<name>.skipDefaultUpdate

  If true, this remote will be skipped by default when updating using git-fetch(1) or the `update` subcommand of git-remote(1).

remote.<name>.skipFetchAll

  If true, this remote will be skipped by default when updating using git-fetch(1) or the `update` subcommand of git-remote(1).

remote.<name>.receivepack

  The default program to execute on the remote side when pushing. See option --receive-pack of git-push(1).

remote.<name>.uploadpack

  The default program to execute on the remote side when fetching. See option --upload-pack of git-fetch-pack(1).

remote.<name>.tagopt

  Setting this value to --no-tags disables automatic tag following when fetching from remote <name>. Setting it to --tags will fetch every tag from remote <name>, even if they are not reachable from remote branch heads. Passing these flags directly to git-fetch(1) can override this setting. See options --tags and --no-tags of git-fetch(1).

remote.<name>.vcs

  Setting this to a value <vcs> will cause git to interact with the remote with the git-remote-<vcs> helper.

remotes.<group>

  The list of remotes which are fetched by "git remote update <group>". See git-remote(1).

repack.usedeltabaseoffset

  By default, git-repack(1) creates packs that use delta-base offset. If you need to share your repository with git older than version 1.4.4, either directly or via a dumb protocol such as http, then you need to set this option to "false" and repack. Access from old git versions over the native protocol are unaffected by this option.

rerere.autoupdate

  When set to true, `git-rerere` updates the index with the resulting contents after it cleanly resolves conflicts using previously recorded resolution. Defaults to false.

rerere.enabled

  Activate recording of resolved conflicts, so that identical conflict hunks can be resolved automatically, should they be encountered again. git-rerere(1) command is by default enabled if you create `rr-cache` directory under `$GIT_DIR`, but can be disabled by setting this option to false.

sendemail.identity

  A configuration identity. When given, causes values in the sendemail.<identity> subsection to take precedence over values in the sendemail section. The default identity is the value of sendemail.identity.

sendemail.smtpencryption

  See git-send-email(1) for description. Note that this setting is not subject to the identity mechanism.

sendemail.smtpssl

  Deprecated alias for sendemail.smtpencryption = ssl.

sendemail.<identity>.*

  Identity-specific versions of the sendemail.* parameters found below, taking precedence over those when the this identity is selected, through command-line or sendemail.identity.

sendemail.aliasesfile

sendemail.signedoffcc

  Deprecated alias for sendemail.signedoffbycc.

showbranch.default

  The default set of branches for git-show-branch(1). See git-show-branch(1).

status.relativePaths

  By default, git-status(1) shows paths relative to the current directory. Setting this variable to `false` shows paths relative to the repository root (this was the default for git prior to v1.5.4).

status.showUntrackedFiles

  By default, git-status(1) and git-commit(1) show files which are not currently tracked by Git. Directories which contain only untracked files, are shown with the directory name only. Showing untracked files means that Git needs to lstat() all all the files in the whole repository, which might be slow on some systems. So, this variable controls how the commands displays the untracked files. Possible values are:

  - `no` - Show no untracked files.

  - `normal` - Show untracked files and directories.

  - `all` - Show also individual files in untracked directories.

  If this variable is not specified, it defaults to normal. This variable can be overridden with the -u|--untracked-files option of git-status(1) and git-commit(1).

status.submodulesummary

  Defaults to false. If this is set to a non zero number or true (identical to -1 or an unlimited number), the submodule summary will be enabled and a summary of commits for modified submodules will be shown (see --summary-limit option of git-submodule(1)).

submodule.<name>.path
submodule.<name>.url
submodule.<name>.update

  The path within this project, URL, and the updating strategy for a submodule. These variables are initially populated by git submodule init; edit them to override the URL and other values found in the `.gitmodules` file. See git-submodule(1) and gitmodules(5) for details.

submodule.<name>.fetchRecurseSubmodules

  This option can be used to enable/disable recursive fetching of this submodule. It can be overridden by using the --[no-]recurse-submodules command line option to "git fetch" and "git pull". This setting will override that from in the gitmodules(5) file.

submodule.<name>.ignore

  Defines under what circumstances "git status" and the diff family show a submodule as modified. When set to "all", it will never be considered modified, "dirty" will ignore all changes to the submodules work tree and takes only differences between the HEAD of the submodule and the commit recorded in the superproject into account. "untracked" will additionally let submodules with modified tracked files in their work tree show up. Using "none" (the default when this option is not set) also shows submodules that have untracked files in their work tree as changed. This setting overrides any setting made in .gitmodules for this submodule, both settings can be overridden on the command line by using the "--ignore-submodules" option.

tar.umask

  This variable can be used to restrict the permission bits of tar archive entries. The default is 0002, which turns off the world write bit. The special value "user" indicates that the archiving user’s umask will be used instead. See umask(2) and git-archive(1).

transfer.unpackLimit

  When `fetch.unpackLimit` or `receive.unpackLimit` are not set, the value of this variable is used instead. The default value is 100.

url.<base>.insteadOf

  Any URL that starts with this value will be rewritten to start, instead, with <base>. In cases where some site serves a large number of repositories, and serves them with multiple access methods, and some users need to use different access methods, this feature allows people to specify any of the equivalent URLs and have git automatically rewrite the URL to the best alternative for the particular user, even for a never-before-seen repository on the site. When more than one insteadOf strings match a given URL, the longest match is used.

url.<base>.pushInsteadOf

  Any URL that starts with this value will not be pushed to; instead, it will be rewritten to start with <base>, and the resulting URL will be pushed to. In cases where some site serves a large number of repositories, and serves them with multiple access methods, some of which do not allow push, this feature allows people to specify a pull-only URL and have git automatically use an appropriate URL to push, even for a never-before-seen repository on the site. When more than one pushInsteadOf strings match a given URL, the longest match is used. If a remote has an explicit pushurl, git will ignore this setting for that remote.

user.email

  Your email address to be recorded in any newly created commits. Can be overridden by the GIT_AUTHOR_EMAIL, GIT_COMMITTER_EMAIL, and EMAIL environment variables. See git-commit-tree(1).

user.name

  Your full name to be recorded in any newly created commits. Can be overridden by the GIT_AUTHOR_NAME and GIT_COMMITTER_NAME environment variables. See git-commit-tree(1).

user.signingkey

  If git-tag(1) is not selecting the key you want it to automatically when creating a signed tag, you can override the default selection with this variable. This option is passed unchanged to gpg’s --local-user parameter, so you may specify a key using any method that gpg supports.

web.browser

  Specify a web browser that may be used by some commands. Currently only git-instaweb(1) and git-help(1) may use it.
