config.txt

CONFIGURATION FILE
------------------

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

They can be used by both the git plumbing
and the porcelains. The variables are divided into sections, where
in the fully qualified variable name 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 section
header before 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 example below:

--------
[section "subsection"]

--------

Subsection names can contain any characters except newline (doublequote
`"` and backslash have to be escaped as `\"` and `\\`,
respectively) and are case sensitive. Section header 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 (case insensitive) alternative `[section.subsection]` syntax.
In this syntax subsection names follow the same restrictions as for section
name.

All the other lines 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 value in double quotes if you want to
preserve leading or trailing whitespace, or if variable value contains
beginning of comment characters (if it contains '#' or ';').
Double quote `"` and backslash `\` characters in variable value 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 value ending in a `\` is continued on the next line in the
customary UNIX fashion.

Some variables may require 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.

core.fileMode::
If false, the executable bit differences between the index and
the working copy are ignored; useful on broken filesystems like FAT.
See linkgit:git-update-index[1]. True by default.

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.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 linkgit: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.autocrlf::
If true, makes git convert `CRLF` at the end of lines in text files to
`LF` when reading from the filesystem, and convert in reverse when
writing to the filesystem. The variable can be set to
'input', in which case the conversion happens only while
reading from the filesystem but files are written out with
`LF` at the end of lines. Currently, which paths to consider
"text" (i.e. be subjected to the autocrlf mechanism) is
decided purely based on the contents.

core.safecrlf::
If true, makes git check if converting `CRLF` as controlled by
`core.autocrlf` is reversible. 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.
autocrlf=true 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.autocrlf`, but only for the current one. For example, a text
file with `LF` would be accepted with `core.autocrlf=input` and could
later be checked out with `core.autocrlf=true`, 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.symlinks::
If false, symbolic links are checked out as small plain files that
contain the link text. linkgit:git-update-index[1] and
linkgit:git-add[1] will not change the recorded type to regular
file. Useful on filesystems like FAT that do not support
symbolic links. True by default.

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 linkgit: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 linkgit:git-add[1] or linkgit:git-merge[1].
+
This setting is automatically guessed by linkgit:git-clone[1] or
linkgit: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 working tree. The value will not be
used in combination with repositories found automatically in
a .git directory (i.e. $GIT_DIR is not set).
This can be overridden by the GIT_WORK_TREE environment
variable and the '--work-tree' command line option. It can be
a absolute path or relative path to the directory specified by
--git-dir or GIT_DIR.
Note: If --git-dir or GIT_DIR are specified but none of
--work-tree, GIT_WORK_TREE and core.worktree is specified,
the current working directory is regarded as the top directory
of your 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 linkgit: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.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 multiple deltafied objects reference. 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.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. See
linkgit:gitignore[5].

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. The order of preference is
`GIT_EDITOR` environment, `core.editor`, `VISUAL` and
`EDITOR` environment variables and then finally `vi`.

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`):
+
* `trailing-space` 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).
* `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).

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.

alias.*::
Command aliases for the linkgit: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".

apply.whitespace::
Tells 'git-apply' how to handle whitespaces, in the same way
as the '--whitespace' option. See linkgit:git-apply[1].

branch.autosetupmerge::
Tells 'git-branch' and 'git-checkout' to setup new branches
so that linkgit: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 branch; `always` -- automatic setup is
done when the starting point is either a local branch or remote
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 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 equal to that of linkgit: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 linkgit: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 linkgit: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 linkgit:git-help[1]) or a
working repository in gitweb (see linkgit: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
linkgit: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 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), `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.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.external::
The string value of this variable is passed to an external 'grep'
command as a command line option if match highlighting is turned
on. If set to an empty string, no option is passed at all,
turning off coloring for external 'grep' calls; this is the default.
For GNU grep, set it to `--color=always` to highlight matches even
when a pager is used.

color.grep.match::
Use customized color for matches. The value of this variable
may be specified as in color.branch.<slot>. It is passed using
the environment variables 'GREP_COLOR' and 'GREP_COLORS' when
calling an external 'grep'.

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
programs. 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.status::
A boolean to enable/disable color in the output of
linkgit: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), 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.template::
Specify a file to use as the template for new commit messages.

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 linkgit:git[1]. Note: if
you want to use an external diff program only on a subset of
your files, you	might want to use linkgit: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.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.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 linkgit: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.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.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 linkgit:git-format-patch[1].

format.headers::
Additional email headers to include in a patch to be submitted
by mail. See linkgit:git-format-patch[1].

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 linkgit:git-log[1], linkgit:git-show[1],
linkgit:git-whatchanged[1].

format.thread::
The default threading style for 'git-format-patch'. Can be
either a boolean value, `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 10.

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::
'git-gc' does not run `git pack-refs` in a bare repository by
default so that older dumb-transport clients can still fetch
from the repository. Setting this to `true` lets 'git-gc'
to run `git pack-refs`. Setting this to `false` tells
'git-gc' never to run `git pack-refs`. The default setting is
`notbare`. Enable it only when you know you do not have to
support such clients. The default setting will change to `true`
at some stage, and setting this to `false` will continue to
prevent `git pack-refs` from being run from 'git-gc'.

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::
'git-reflog expire' removes reflog entries older than
this time; defaults to 90 days.

gc.reflogexpireunreachable::
'git-reflog expire' removes reflog entries older than
this time and are not reachable from the current tip;
defaults to 30 days.

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 linkgit: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 linkgit: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 linkgit:git-cvsserver[1].

gitcvs.logfile::
Path to a log file where the CVS server interface well... logs
various stuff. See linkgit:git-cvsserver[1].

gitcvs.usecrlfattr::
If true, the server will look up the `crlf` attribute for
files to determine the '-k' modes to use. If `crlf` is set,
the '-k' mode will be left blank, so cvs clients will
treat it as text. If `crlf` is explicitly unset, the file
will be set with '-kb' mode, which suppresses any newline munging
the client might otherwise do. If `crlf` is not specified,
then 'gitcvs.allbinary' is used. See linkgit: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
linkgit: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 linkgit: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
linkgit: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
linkgit: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
linkgit:git-gui[1]. "75" is the default.

gui.diffcontext::
Specifies how many context lines should be used in calls to diff
made by the linkgit:git-gui[1]. The default is "5".

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

gui.matchtrackingbranch::
Determines if new branches created with linkgit: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
linkgit:git-gui[1].

gui.pruneduringfetch::
"true" if linkgit:git-gui[1] should prune tracking branches when
performing a fetch. The default value is "false".

gui.trustmtime::
Determines if linkgit: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 linkgit: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
linkgit:git-blame[1] manual for more information on copy detection.

gui.blamehistoryctx::
Specifies the radius of history context in days to show in
linkgit: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 linkgit: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 linkgit:git-help[1].

help.format::
Override the default help format used by linkgit: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 linkgit: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.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.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).

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. linkgit: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 linkgit:git-imap-send[1].

instaweb.browser::
Specify the program that will be used to browse your working
repository in gitweb. See linkgit:git-instaweb[1].

instaweb.httpd::
The HTTP daemon command-line to start gitweb on your working
repository. See linkgit:git-instaweb[1].

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

instaweb.modulepath::
The module path for an apache httpd used by linkgit:git-instaweb[1].

instaweb.port::
The port number to bind the gitweb httpd to. See
linkgit:git-instaweb[1].

interactive.singlekey::
In interactive programs, 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
linkgit:git-add[1]. Note that this setting is silently
ignored if portable keystroke input is not available.

log.date::
Set default date-time mode for the log command. Setting log.date
value is similar to using 'git-log'\'s --date option. The value is one of the
following alternatives: {relative,local,default,iso,rfc,short}.
See linkgit:git-log[1].

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
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 linkgit:git-shortlog[1] and linkgit:git-blame[1].

man.viewer::
Specify the programs that may be used to display help in the
'man' format. See linkgit: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 linkgit: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 linkgit:git-help[1].

include::merge-config.txt[]

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.

pack.window::
The size of the window used by linkgit: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 linkgit: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 linkgit: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)."

pack.deltaCacheSize::
The maximum memory in bytes used for caching deltas in
linkgit:git-pack-objects[1].
A value of 0 means no limit. Defaults to 0.

pack.deltaCacheLimit::
The maximum size of a delta, that is cached in
linkgit:git-pack-objects[1]. Defaults to 1000.

pack.threads::
Specifies the number of threads to spawn when searching for best
delta matches. This requires that linkgit: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 `{asterisk}.idx` file,
cloning or fetching over a non native protocol (e.g. "http" and "rsync")
that will copy both `{asterisk}.pack` file and corresponding `{asterisk}.idx` file from the
other side may give you a repository that cannot be accessed with your
older version of git. If the `{asterisk}.pack` file is smaller than 2 GB, however,
you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
the `{asterisk}.idx` file.

pack.packSizeLimit::
The default maximum size of a pack. This setting only affects
packing to a file, i.e. the git:// protocol is unaffected. It
can be overridden by the `\--max-pack-size` option of
linkgit:git-repack[1].

pager.<cmd>::
Allows turning on or off pagination of the output of a
particular git subcommand when writing to a tty. 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`.

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.

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.denyCurrentBranch::
If set to true or "refuse", 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 "warn".

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.

remote.<name>.url::
The URL of a remote repository. See linkgit:git-fetch[1] or
linkgit: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 linkgit:git-fetch[1]. See
linkgit:git-fetch[1].

remote.<name>.push::
The default set of "refspec" for linkgit:git-push[1]. See
linkgit: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 the update subcommand of linkgit:git-remote[1].

remote.<name>.receivepack::
The default program to execute on the remote side when pushing. See
option \--receive-pack of linkgit:git-push[1].

remote.<name>.uploadpack::
The default program to execute on the remote side when fetching. See
option \--upload-pack of linkgit:git-fetch-pack[1].

remote.<name>.tagopt::
Setting this value to \--no-tags disables automatic tag following when
fetching from remote <name>

remotes.<group>::
The list of remotes which are fetched by "git remote update
<group>". See linkgit:git-remote[1].

repack.usedeltabaseoffset::
By default, linkgit: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. linkgit: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.

showbranch.default::
The default set of branches for linkgit:git-show-branch[1].
See linkgit:git-show-branch[1].

status.relativePaths::
By default, linkgit: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, linkgit:git-status[1] and linkgit: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' - Shows untracked files and directories
- 'all' - Shows 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 linkgit:git-status[1] and linkgit:git-commit[1].

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
linkgit: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.

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 linkgit: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 linkgit:git-commit-tree[1].

user.signingkey::
If linkgit: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 linkgit:git-instaweb[1] and linkgit:git-help[1]
may use it.
