Only git-ls-files(1) describes the gitignore format in detail, and it does so with reference to git-ls-files options. Most users don't use the plumbing command git-ls-files directly, and shouldn't have to look in its manpage for information on the gitignore format. Create a new manpage gitignore(5) (Documentation/gitignore.txt), and factor out the gitignore documentation into that file, changing it to refer to .gitignore and $GIT_DIR/info/exclude as used by porcelain commands. Reference gitignore(5) from other relevant manpages and documentation. Remove now-redundant information on exclude patterns from git-ls-files(1), leaving only information on how git-ls-files options specify exclude patterns and what precedence they have.

NAME

----
|
|
gitignore - Specifies intentionally untracked files to ignore
|
|
|

SYNOPSIS
|
|
--------
|
|
$GIT_DIR/info/exclude, .gitignore
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
A `gitignore` file specifies intentionally untracked files that
|
|
git should ignore. Each line in a `gitignore` file specifies a
|
|
pattern.
|
|
|
|
When deciding whether to ignore a path, git normally checks
|
|
`gitignore` patterns from multiple sources, with the following
|
|
order of precedence:
|
|
|
|
* Patterns read from the file specified by the configuration
|
|
variable 'core.excludesfile'.
|
|
|
|
* Patterns read from `$GIT_DIR/info/exclude`.
|
|
|
|
* Patterns read from a `.gitignore` file in the same directory
|
|
as the path, or in any parent directory, ordered from the
|
|
deepest such file to a file in the root of the repository.
|
|
These patterns match relative to the location of the
|
|
`.gitignore` file. A project normally includes such
|
|
`.gitignore` files in its repository, containing patterns for
|
|
files generated as part of the project build.
|
|
|
|
The underlying git plumbing tools, such as
|
|
gitlink:git-ls-files[1] and gitlink:git-read-tree[1], read
|
|
`gitignore` patterns specified by command-line options, or from
|
|
files specified by command-line options. Higher-level git
|
|
tools, such as gitlink:git-status[1] and gitlink:git-add[1],
|
|
use patterns from the sources specified above.
|
|
|
|
Patterns have the following format:
|
|
|
|
- A blank line matches no files, so it can serve as a separator
|
|
for readability.
|
|
|
|
- A line starting with # serves as a comment.
|
|
|
|
- An optional prefix '!' which negates the pattern; any
|
|
matching file excluded by a previous pattern will become
|
|
included again.
|
|
|
|
- If the pattern does not contain a slash '/', git treats it as
|
|
a shell glob pattern and checks for a match against the
|
|
pathname without leading directories.
|
|
|
|
- Otherwise, git treats the pattern as a shell glob suitable
|
|
for consumption by fnmatch(3) with the FNM_PATHNAME flag:
|
|
wildcards in the pattern will not match a / in the pathname.
|
|
For example, "Documentation/\*.html" matches
|
|
"Documentation/git.html" but not
|
|
"Documentation/ppc/ppc.html". A leading slash matches the
|
|
beginning of the pathname; for example, "/*.c" matches
|
|
"cat-file.c" but not "mozilla-sha1/sha1.c".
|
|
|
|
An example:
|
|
|
|
--------------------------------------------------------------
|
|
$ 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`.
