SYNOPSIS

$HOME/.config/git/ignore, $GIT_DIR/info/exclude, .gitignore

DESCRIPTION

A gitignore file specifies intentionally untracked files that Git should ignore. Files already tracked by Git are not affected; see the NOTES below for details.

Each line in a gitignore file specifies a pattern. When deciding whether to ignore a path, Git normally checks gitignore patterns from multiple sources, with the following order of precedence, from highest to lowest (within one level of precedence, the last matching pattern decides the outcome):

Which file to place a pattern in depends on how the pattern is meant to be used.

The underlying Git plumbing tools, such as git ls-files and git read-tree, read gitignore patterns specified by command-line options, or from files specified by command-line options. Higher-level Git tools, such as git status and git add, use patterns from the sources specified above.

PATTERN FORMAT

Two consecutive asterisks ("**") in patterns matched against full pathname may have special meaning:

NOTES

The purpose of gitignore files is to ensure that certain files not tracked by Git remain untracked.

To stop tracking a file that is currently tracked, use git rm --cached.

EXAMPLES

    $ git status
    [...]
    # Untracked files:
    [...]
    #       Documentation/foo.html
    #       Documentation/gitignore.html
    #       file.o
    #       lib.a
    #       src/internal.o
    [...]
    $ cat .git/info/exclude
    # ignore objects and archives, anywhere in the tree.
    *.[oa]
    $ cat Documentation/.gitignore
    # ignore generated html files,
    *.html
    # except foo.html which is maintained by hand
    !foo.html
    $ git status
    [...]
    # Untracked files:
    [...]
    #       Documentation/foo.html
    [...]

Another example:

    $ cat .gitignore
    vmlinux*
    $ ls arch/foo/kernel/vm*
    arch/foo/kernel/vmlinux.lds.S
    $ echo '!/vmlinux*' >arch/foo/kernel/.gitignore

The second .gitignore prevents Git from ignoring arch/foo/kernel/vmlinux.lds.S.

Example to exclude everything except a specific directory foo/bar (note the /* - without the slash, the wildcard would also exclude everything within foo/bar):

    $ cat .gitignore
    # exclude everything except directory foo/bar
    /*
    !/foo
    /foo/*
    !/foo/bar
