6 gitignore - Specifies intentionally untracked files to ignore
10 $GIT_DIR/info/exclude, .gitignore
15 A `gitignore` file specifies intentionally untracked files that
17 Files already tracked by git are not affected; see the NOTES
20 Each line in a `gitignore` file specifies a pattern.
21 When deciding whether to ignore a path, git normally checks
22 `gitignore` patterns from multiple sources, with the following
23 order of precedence, from highest to lowest (within one level of
24 precedence, the last matching pattern decides the outcome):
26 * Patterns read from the command line for those commands that support
29 * Patterns read from a `.gitignore` file in the same directory
30 as the path, or in any parent directory, with patterns in the
31 higher level files (up to the toplevel of the work tree) being overridden
32 by those in lower level files down to the directory containing the file.
33 These patterns match relative to the location of the
34 `.gitignore` file. A project normally includes such
35 `.gitignore` files in its repository, containing patterns for
36 files generated as part of the project build.
38 * Patterns read from `$GIT_DIR/info/exclude`.
40 * Patterns read from the file specified by the configuration
41 variable 'core.excludesfile'.
43 Which file to place a pattern in depends on how the pattern is meant to
44 be used. Patterns which should be version-controlled and distributed to
45 other repositories via clone (i.e., files that all developers will want
46 to ignore) should go into a `.gitignore` file. Patterns which are
47 specific to a particular repository but which do not need to be shared
48 with other related repositories (e.g., auxiliary files that live inside
49 the repository but are specific to one user's workflow) should go into
50 the `$GIT_DIR/info/exclude` file. Patterns which a user wants git to
51 ignore in all situations (e.g., backup or temporary files generated by
52 the user's editor of choice) generally go into a file specified by
53 `core.excludesfile` in the user's `~/.gitconfig`.
55 The underlying git plumbing tools, such as
56 'git ls-files' and 'git read-tree', read
57 `gitignore` patterns specified by command-line options, or from
58 files specified by command-line options. Higher-level git
59 tools, such as 'git status' and 'git add',
60 use patterns from the sources specified above.
65 - A blank line matches no files, so it can serve as a separator
68 - A line starting with # serves as a comment.
70 - An optional prefix '!' which negates the pattern; any
71 matching file excluded by a previous pattern will become
72 included again. If a negated pattern matches, this will
73 override lower precedence patterns sources.
75 - If the pattern ends with a slash, it is removed for the
76 purpose of the following description, but it would only find
77 a match with a directory. In other words, `foo/` will match a
78 directory `foo` and paths underneath it, but will not match a
79 regular file or a symbolic link `foo` (this is consistent
80 with the way how pathspec works in general in git).
82 - If the pattern does not contain a slash '/', git treats it as
83 a shell glob pattern and checks for a match against the
84 pathname relative to the location of the `.gitignore` file
85 (relative to the toplevel of the work tree if not from a
88 - Otherwise, git treats the pattern as a shell glob suitable
89 for consumption by fnmatch(3) with the FNM_PATHNAME flag:
90 wildcards in the pattern will not match a / in the pathname.
91 For example, "Documentation/{asterisk}.html" matches
92 "Documentation/git.html" but not "Documentation/ppc/ppc.html"
93 or "tools/perf/Documentation/perf.html".
95 - A leading slash matches the beginning of the pathname.
96 For example, "/{asterisk}.c" matches "cat-file.c" but not
97 "mozilla-sha1/sha1.c".
102 The purpose of gitignore files is to ensure that certain files
103 not tracked by git remain untracked.
105 To ignore uncommitted changes in a file that is already tracked,
106 use 'git update-index {litdd}assume-unchanged'.
108 To stop tracking a file that is currently tracked, use
