Syntax
~~~~~~
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
+section begins. Section names are case-insensitive. 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.
--------
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
+newline (doublequote `"` and backslash can be included by escaping them
+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.
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".
+'name = value' (or just 'name', which is a short-hand to say that
+the variable is the boolean "true").
The variable names are case-insensitive, allow only alphanumeric characters
-and `-`, and must start with an alphabetic character. There can be more
-than one value for a given variable; we say then that the variable is
-multivalued.
-
-Leading and trailing whitespace in a variable value is discarded.
-Internal whitespace within a variable value is retained verbatim.
+and `-`, and must start with an alphabetic character.
-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,
-1/0, 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".
+A line that defines a value can be continued to the next line by
+ending it with a `\`; the backquote and the end-of-line are
+stripped. Leading whitespaces after 'name =', the remainder of the
+line after the first comment character '#' or ';', and trailing
+whitespaces of the line are discarded unless they are enclosed in
+double quotes. Internal whitespaces within the value are retained
+verbatim.
-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 `\`.
+Inside double quotes, double quote `"` and backslash `\` characters
+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). Other char escape sequences (including octal
escape sequences) are invalid.
-Variable values ending in a `\` are continued on the next line in the
-customary UNIX fashion.
-
-Some variables may require a special value format.

+
+Values
+~~~~~~
+
+Values of many variables are treated as a simple string, but there
+are variables that take values of specific types and there are rules
+as to how to spell them.
+
+boolean::
+
+ When a variable is said to take a boolean value, many
+ synonyms are accepted for 'true' and 'false'; these are all
+ case-insensitive.
+
+ true;; Boolean true can be spelled as `yes`, `on`, `true`,
+ or `1`. Also, a variable defined without `= <value>`
+ is taken as true.
+
+ false;; Boolean false can be spelled as `no`, `off`,
+ `false`, or `0`.
++
+When converting value to the canonical form using '--bool' type
+specifier; 'git config' will ensure that the output is "true" or
+"false" (spelled in lowercase).
+
+integer::
+ The value for many variables that specify various sizes can
+ be suffixed with `k`, `M`,... to mean "scale the number by
+ 1024", "by 1024x1024", etc.
+
+color::
+ The value for a variables that takes a color 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. Attributes may be turned off specifically
+ by prefixing them with `no` (e.g., `noreverse`, `noul`, etc).
++
+Colors (foreground and background) may also be given as numbers between
+0 and 255; these use ANSI 256-color mode (but note that not all
+terminals may support this). If your terminal supports it, you may also
+specify 24-bit RGB values as hex, like `#ff0ab3`.
++
+The attributes are meant to be reset at the beginning of each item
+in the colored output, so setting color.decorate.branch to `black`
+will paint that branch name in a plain `black`, even if the previous
+thing on the same output line (e.g. opening parenthesis before the
+list of branch names in `log --decorate` output) is set to be
+painted with `bold` or some other attribute.

Variables
~~~~~~~~~
+
The default is true (when core.filemode is not specified in the config file).
-core.ignorecase::
+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".

-core.precomposeunicode::
+core.precomposeUnicode::
This option is only used by Mac OS implementation of Git.
- When core.precomposeunicode=true, Git reverts the unicode decomposition
+ When core.precomposeUnicode=true, Git reverts the unicode decomposition
of filenames done by Mac OS. This is useful when sharing a repository
between Mac OS and Linux or Windows.
(Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7).
When false, file names are handled fully transparent by Git,
which is backward compatible with older versions of Git.
+core.protectHFS::
+ If set to true, do not allow checkout of paths that would
+ be considered equivalent to `.git` on an HFS+ filesystem.
+ Defaults to `true` on Mac OS, and `false` elsewhere.
+
+core.protectNTFS::
+ If set to true, do not allow checkout of paths that would
+ cause problems with the NTFS filesystem, e.g. conflict with
+ 8.3 "short" names.
+ Defaults to `true` on Windows, and `false` elsewhere.
+
core.trustctime::
If false, the ctime differences between the index and the
working tree are ignored; useful when the inode change time
crawlers and some backup systems).
See linkgit:git-update-index[1]. True by default.
-core.checkstat::
+core.checkStat::
Determines which stat fields to match between the index
and work tree. The user can set this to 'default' or
'minimal'. Default (or explicitly 'default'), is to check
all fields, including the sub-second part of mtime and ctime.
-core.quotepath::
+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
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 tree, 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 linkgit:git-update-index[1].
- False by default.
+ If true, Git will avoid using lstat() calls to detect if files have
+ changed by setting the "assume-unchanged" bit for those tracked files
+ which it has updated identically in both the index and working tree.
++
+When files are modified outside of Git, the user will need to stage
+the modified files explicitly (e.g. see 'Examples' section in
+linkgit:git-update-index[1]).
+Git will not normally detect changes to those files.
++
+This is useful on systems where lstat() calls are very slow, such as
+CIFS/Microsoft Windows.
++
+False by default.
core.preferSymlinkRefs::
Instead of the default "symref" format for HEAD
core.worktree::
Set the path to the root of the working tree.
+ If GIT_COMMON_DIR environment variable is set, core.worktree

Common unit suffixes of 'k', 'm', or 'g' are supported.
-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
If $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/ignore

-core.askpass::
+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'
prompt. The external program shall be given a suitable prompt as
command-line argument and write the password on its STDOUT.
-core.attributesfile::

messages consider a line that begins with this character
commented, and removes them after the editor returns
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::
+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
journalling (traditional UNIX filesystems) or that only journal metadata
and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").

This can speed up operations like 'git diff' and 'git status' especially
for abbreviated object names to stay unique for sufficiently long
time.
-add.ignore-errors::
add.ignoreErrors::
+add.ignore-errors (deprecated)::
Tells 'git add' to continue adding files when some files cannot be
added due to indexing errors. Equivalent to the '--ignore-errors'

This is the same as the log commands '--decorate' option.
-log.showroot::
+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 linkgit:git-log[1] or linkgit:git-whatchanged[1], which

When set to true, automatically create a temporary stash
before the operation begins, and apply it after the operation
ends. This means that you can run rebase on a dirty worktree.
successful rebase might result in non-trivial conflicts.

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.certnonceseed::
+receive.certNonceSeed::
By setting this variable to a string, `git receive-pack`
will accept a `git push --signed` and verifies it by using
a "nonce" protected by HMAC using this string as a secret

+Another option is "updateInstead" which will update the working
+tree if pushing into the current branch. This option is
+intended for synchronizing working directories when one side is not easily

------------
+ MULTIPLE WORKING TREES
+ ----------------------
+
+ A git repository can support multiple working trees, allowing you to check
+ out more than one branch at a time. With `git checkout --to` a new working
+ tree is associated with the repository. This new working tree is called a
+ "linked working tree" as opposed to the "main working tree" prepared by "git
+ init" or "git clone". A repository has one main working tree (if it's not a
+ bare repository) and zero or more linked working trees.
+
+ Each linked working tree has a private sub-directory in the repository's
+ $GIT_DIR/worktrees directory. The private sub-directory's name is usually
+ the base name of the linked working tree's path, possibly appended with a
+ number to make it unique. For example, when `$GIT_DIR=/path/main/.git` the
+ command `git checkout --to /path/other/test-next next` creates the linked
+ working tree in `/path/other/test-next` and also creates a
+ `$GIT_DIR/worktrees/test-next` directory (or `$GIT_DIR/worktrees/test-next1`
+ if `test-next` is already taken).
+
+ Within a linked working tree, $GIT_DIR is set to point to this private
+ directory (e.g. `/path/main/.git/worktrees/test-next` in the example) and
+ $GIT_COMMON_DIR is set to point back to the main working tree's $GIT_DIR
+ (e.g. `/path/main/.git`). These settings are made in a `.git` file located at
+ the top directory of the linked working tree.
+
+ Path resolution via `git rev-parse --git-path` uses either
+ $GIT_DIR or $GIT_COMMON_DIR depending on the path. For example, in the
+ linked working tree `git rev-parse --git-path HEAD` returns
+ `/path/main/.git/worktrees/test-next/HEAD` (not
+ `/path/other/test-next/.git/HEAD` or `/path/main/.git/HEAD`) while `git
+ rev-parse --git-path refs/heads/master` uses
+ $GIT_COMMON_DIR and returns `/path/main/.git/refs/heads/master`,
+ since refs are shared across all working trees.
+
+ See linkgit:gitrepository-layout[5] for more information. The rule of
+ thumb is do not make any assumption about whether a path belongs to
+ $GIT_DIR or $GIT_COMMON_DIR when you need to directly access something
+ inside $GIT_DIR. Use `git rev-parse --git-path` to get the final path.
+
+ When you are done with a linked working tree you can simply delete it.
+ The working tree's entry in the repository's $GIT_DIR/worktrees
+ directory will eventually be removed automatically (see
+ `gc.pruneworktreesexpire` in linkgit::git-config[1]), or you can run
+ `git prune --worktrees` in the main or any linked working tree to
+ clean up any stale entries in $GIT_DIR/worktrees.
+
+ If you move a linked working directory to another file system, or
+ within a file system that does not support hard links, you need to run
+ at least one git command inside the linked working directory
+ (e.g. `git status`) in order to update its entry in $GIT_DIR/worktrees
+ so that it does not get automatically removed.
+
+ To prevent a $GIT_DIR/worktrees entry from from being pruned (which
+ can be useful in some situations, such as when the
+ entry's working tree is stored on a portable device), add a file named
+ 'locked' to the entry's directory. The file contains the reason in
+ plain text. For example, if a linked working tree's `.git` file points
+ to `/path/main/.git/worktrees/test-next` then a file named
+ `/path/main/.git/worktrees/test-next/locked` will prevent the
+ `test-next` entry from being pruned. See
+ linkgit:gitrepository-layout[5] for details.
+
+ Multiple checkout support for submodules is incomplete. It is NOT
+ recommended to make multiple checkouts of a superproject.
