git-ignore - Add .gitignore patterns


git-ignore [<context>] [<pattern> [<pattern>]...]


Adds the given _pattern_s to a .gitignore file if it doesn´t already exist.



-l, --local

Sets the context to the .gitignore file in the current working directory. (default)

-g, --global

Sets the context to the global gitignore file for the current user.


A space delimited list of patterns to append to the file in context.

Pattern format as described in the git manual

· A blank line matches no files, so it can serve as a separator for readability. To
append a blank line use empty quotes "".

· A line starting with # serves as a comment. For example, "# This is a comment"

· 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. To use an exclamation ! as command line
argument it is best placed between single quotes ´´. For example, ´!src´

· 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/*.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, "/*.c" matches
"cat-file.c" but not "mozilla-sha1/sha1.c".


All arguments are optional so calling git-ignore alone will display first the global then
the local gitignore files:

$ git ignore
Global gitignore: /home/alice/.gitignore
# Numerous always-ignore extensions

# OS or Editor folders
Local gitignore: .gitignore

If you only want to see the global context use the --global argument (for local use

$ git ignore
Global gitignore: /home/alice/.gitignore

To quickly append a new pattern to the default/local context simply:

$ git ignore *.log
Adding pattern(s) to: .gitignore
`... adding ´*.log´`

You can now configure any patterns without ever using an editor, with a context and
pattern arguments: The resulting configuration is also returned for your convenience.

$ git ignore --local "" "# Temporary files" *.tmp "*.log" tmp/* "" "# Files I´d like to keep" ´!work´ ""
Adding pattern(s) to: .gitignore
`... adding ´´`
`... adding ´# Temporary files´`
`... adding ´index.tmp´`
`... adding ´*.log´`
`... adding ´tmp/*´`
`... adding ´´`
`... adding ´# Files I´d like to keep´`
`... adding ´!work´`
`... adding ´´`

Local gitignore: .gitignore

# Temporary files

# Files I´d like to keep
