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

The git configuration file contains a number of variables that affect
the git command's behavior. 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.

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, lines containing strings enclosed in square
brackets start sections and 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". String values may be entirely or partially
enclosed in double quotes; 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/gnu-diff -u"
                renames = true

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 gitlink:git-update-index[1]. 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).

core.ignoreStat::
        The working copy files are assumed to stay unchanged 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 gitlink: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.logAllRefUpdates::
        If true, `git-update-ref` will append a line to
        "$GIT_DIR/logs/<ref>" listing the new SHA1 and the date/time
        of the update.  If the file does not exist it will be
        created automatically.  This information can be used to
        determine what commit was the tip of a branch "2 days ago".
        This value is false by default (no logging).

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). See gitlink:git-init-db[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 the compression level for objects that
        are not in a pack file. -1 is the zlib and git default. 0 means no
        compression, and 1..9 are various speed/size tradeoffs, 9 being
        slowest.

core.legacyheaders::
        A boolean which enables the legacy object header format in case
        you want to interoperate with old clients accessing the object
        database directly (where the "http://" and "rsync://" protocols
        count as direct access).

alias.*::
        Command aliases for the gitlink: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.

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

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

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

diff.color.<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), or `new` (added lines).  The value for these
        configuration variables can be one of: `normal`, `bold`,
        `dim`, `ul`, `blink`, `reverse`, `reset`, `black`,
        `red`, `green`, `yellow`, `blue`, `magenta`, `cyan`, or
        `white`.

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.

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

gitcvs.enabled::
        Whether the cvs pserver interface is enabled for this repository.
        See gitlink:git-cvsserver[1].

gitcvs.logfile::
        Path to a log file where the cvs pserver interface well... logs
        various stuff. See gitlink:git-cvsserver[1].

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.

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. gitlink:git-mailinfo[1]. Defaults to 'utf-8'.

merge.summary::
        Whether to include summaries of merged commits in newly created
        merge commit messages. False by default.

pack.window::
        The size of the window used by gitlink:git-pack-objects[1] when no
        window size is given on the command line. Defaults to 10.

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.

show.difftree::
        The default gitlink:git-diff-tree[1] arguments to be used
        for gitlink:git-show[1].

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

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

status.color.<slot>::
        Use customized color for status colorization. `<slot>` is
        one of `header` (the header text of the status message),
        `updated` (files which are updated but not committed),
        `changed` (files which are changed but not updated in the index),
        or `untracked` (files which are not tracked by git). The values of
        these variables may be specified as in diff.color.<slot>.

tar.umask::
        By default, gitlink:git-tar-tree[1] sets file and directories modes
        to 0666 or 0777. While this is both useful and acceptable for projects
        such as the Linux Kernel, it might be excessive for other projects.
        With this variable, it becomes possible to tell
        gitlink:git-tar-tree[1] to apply a specific umask to the modes above.
        The special value "user" indicates that the user's current umask will
        be used. This should be enough for most projects, as it will lead to
        the same permissions as gitlink:git-checkout[1] would use. The default
        value remains 0, which means world read-write.

user.email::
        Your email address to be recorded in any newly created commits.
        Can be overridden by the 'GIT_AUTHOR_EMAIL' and 'GIT_COMMITTER_EMAIL'
        environment variables.  See gitlink: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 gitlink:git-commit-tree[1].

whatchanged.difftree::
        The default gitlink:git-diff-tree[1] arguments to be used
        for gitlink:git-whatchanged[1].

imap::
        The configuration variables in the 'imap' section are described
        in gitlink:git-imap-send[1].

receive.denyNonFastforwads::
        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.
