| NAME |
| ---- |
| gitignore - Specifies intentionally untracked files to ignore |
| |
| SYNOPSIS |
| -------- |
| $GIT_DIR/info/exclude, .gitignore |
| |
| DESCRIPTION |
| ----------- |
| |
| A `gitignore` file specifies intentionally untracked files that |
| Git should ignore. |
| Files already tracked by Git are not affected; see the NOTES |
| below for details. |
| |
| Each line in a `gitignore` file specifies a pattern. |
| When deciding whether to ignore a path, Git normally checks |
| `gitignore` patterns from multiple sources, with the following |
| order of precedence, from highest to lowest (within one level of |
| precedence, the last matching pattern decides the outcome): |
| |
| * Patterns read from the command line for those commands that support |
| them. |
| |
| * Patterns read from a `.gitignore` file in the same directory |
| as the path, or in any parent directory, with patterns in the |
| higher level files (up to the toplevel of the work tree) being overridden |
| by those in lower level files down to the directory containing the file. |
| These patterns match relative to the location of the |
| `.gitignore` file. A project normally includes such |
| `.gitignore` files in its repository, containing patterns for |
| files generated as part of the project build. |
| |
| * Patterns read from `$GIT_DIR/info/exclude`. |
| |
| * Patterns read from the file specified by the configuration |
| variable 'core.excludesfile'. |
| |
| Which file to place a pattern in depends on how the pattern is meant to |
| be used. |
| |
| * Patterns which should be version-controlled and distributed to |
| other repositories via clone (i.e., files that all developers will want |
| to ignore) should go into a `.gitignore` file. |
| |
| * Patterns which are |
| specific to a particular repository but which do not need to be shared |
| with other related repositories (e.g., auxiliary files that live inside |
| the repository but are specific to one user's workflow) should go into |
| the `$GIT_DIR/info/exclude` file. |
| |
| * Patterns which a user wants Git to |
| ignore in all situations (e.g., backup or temporary files generated by |
| the user's editor of choice) generally go into a file specified by |
| `core.excludesfile` in the user's `~/.gitconfig`. Its default value is |
| $XDG_CONFIG_HOME/git/ignore. If $XDG_CONFIG_HOME is either not set or |
| empty, $HOME/.config/git/ignore is used instead. |
| |
| 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 |
| -------------- |
| |
| - A blank line matches no files, so it can serve as a separator |
| for readability. |
| |
| - A line starting with # serves as a comment. |
| Put a backslash ("`\`") in front of the first hash for patterns |
| that begin with a hash. |
| |
| - An optional prefix "`!`" which negates the pattern; any |
| matching file excluded by a previous pattern will become |
| included again. If a negated pattern matches, this will |
| override lower precedence patterns sources. |
| Put a backslash ("`\`") in front of the first "`!`" for patterns |
| that begin with a literal "`!`", for example, "`\!important!.txt`". |
| |
| - If the pattern ends with a slash, it is removed for the |
| purpose of the following description, but it would only find |
| a match with a directory. In other words, `foo/` will match a |
| directory `foo` and paths underneath it, but will not match a |
| regular file or a symbolic link `foo` (this is consistent |
| with the way how pathspec works in general in Git). |
| |
| - If the pattern does not contain a slash '/', Git treats it as |
| a shell glob pattern and checks for a match against the |
| pathname relative to the location of the `.gitignore` file |
| (relative to the toplevel of the work tree if not from a |
| `.gitignore` file). |
| |
| - 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/{asterisk}.html" matches |
| "Documentation/git.html" but not "Documentation/ppc/ppc.html" |
| or "tools/perf/Documentation/perf.html". |
| |
| - A leading slash matches the beginning of the pathname. |
| For example, "/{asterisk}.c" matches "cat-file.c" but not |
| "mozilla-sha1/sha1.c". |
| |
| Two consecutive asterisks ("`**`") in patterns matched against |
| full pathname may have special meaning: |
| |
| - A leading "`**`" followed by a slash means match in all |
| directories. For example, "`**/foo`" matches file or directory |
| "`foo`" anywhere, the same as pattern "`foo`". "**/foo/bar" |
| matches file or directory "`bar`" anywhere that is directly |
| under directory "`foo`". |
| |
| - A trailing "/**" matches everything inside. For example, |
| "abc/**" matches all files inside directory "abc", relative |
| to the location of the `.gitignore` file, with infinite depth. |
| |
| - A slash followed by two consecutive asterisks then a slash |
| matches zero or more directories. For example, "`a/**/b`" |
| matches "`a/b`", "`a/x/b`", "`a/x/y/b`" and so on. |
| |
| - Other consecutive asterisks are considered invalid. |
| |
| NOTES |
| ----- |
| |
| The purpose of gitignore files is to ensure that certain files |
| not tracked by Git remain untracked. |
| |
| To ignore uncommitted changes in a file that is already tracked, |
| use 'git update-index {litdd}assume-unchanged'. |
| |
| 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`. |
