CONFIGURATION FILE
------------------
The git configuration file contains a number of variables that affect
the git commands behaviour. They can be used by both the git plumbing
and the porcelains. The variables are divided to 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 commends 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 more detailed description
in the appropriate manual page. You will find 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 overriden 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.onlyUseSymrefs::
Always use the "symref" format instead of symbolic links for HEAD
and other symbolic reference files. True by default.
core.repositoryFormatVersion::
Internal variable identifying the repository format and layout
version.
core.sharedRepository::
If true, the repository is made shareable between several users
in a group (making sure all the files and objects are group-writable).
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.
apply.whitespace::
Tells `git-apply` how to handle whitespaces, in the same way
as the '--whitespace' option. See gitlink:git-apply[1].
diff.renameLimit::
The number of files to consider when performing the copy/rename
detection; equivalent to the git diff option '-l'.
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 overriden by the 'GIT_SSL_NO_VERIFY' environment
variable.
http.sslCert::
File containing the SSL certificate when fetching or pushing
over HTTPS. Can be overriden by the 'GIT_SSL_CERT' environment
variable.
http.sslKey::
File containing the SSL private key when fetching or pushing
over HTTPS. Can be overriden 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 overriden 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 overriden
by the 'GIT_SSL_CAPATH' environment variable.
http.maxRequests::
How many HTTP requests to launch in parallel. Can be overriden
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 overriden 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.
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].
user.email::
Your email address to be recorded in any newly created commits.
Can be overriden 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 overriden 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].
