git-check-ignore(1)
===================
NAME
----
git-check-ignore - Debug gitignore / exclude files
SYNOPSIS
--------
[verse]
'git check-ignore' [options] pathname...
'git check-ignore' [options] --stdin < <list-of-paths>
DESCRIPTION
-----------
For each pathname given via the command-line or from a file via
`--stdin`, show the pattern from .gitignore (or other input files to
the exclude mechanism) that decides if the pathname is excluded or
included. Later patterns within a file take precedence over earlier
ones.
OPTIONS
-------
-q, --quiet::
Don't output anything, just set exit status. This is only
valid with a single pathname.
-v, --verbose::
Also output details about the matching pattern (if any)
for each given pathname.
--stdin::
Read file names from stdin instead of from the command-line.
-z::
The output format is modified to be machine-parseable (see
below). If `--stdin` is also given, input paths are separated
with a NUL character instead of a linefeed character.
-n, --non-matching::
Show given paths which don't match any pattern. This only
makes sense when `--verbose` is enabled, otherwise it would
not be possible to distinguish between paths which match a
pattern and those which don't.
OUTPUT
------
By default, any of the given pathnames which match an ignore pattern
will be output, one per line. If no pattern matches a given path,
nothing will be output for that path; this means that path will not be
ignored.
If `--verbose` is specified, the output is a series of lines of the form:
<source> <COLON> <linenum> <COLON> <pattern> <HT> <pathname>
<pathname> is the path of a file being queried, <pattern> is the
matching pattern, <source> is the pattern's source file, and <linenum>
is the line number of the pattern within that source. If the pattern
contained a `!` prefix or `/` suffix, it will be preserved in the
output. <source> will be an absolute path when referring to the file
configured by `core.excludesfile`, or relative to the repository root
when referring to `.git/info/exclude` or a per-directory exclude file.
If `-z` is specified, the pathnames in the output are delimited by the
null character; if `--verbose` is also specified then null characters
are also used instead of colons and hard tabs:
<source> <NULL> <linenum> <NULL> <pattern> <NULL> <pathname> <NULL>
If `-n` or `--non-matching` are specified, non-matching pathnames will
also be output, in which case all fields in each output record except
for <pathname> will be empty. This can be useful when running
non-interactively, so that files can be incrementally streamed to
STDIN of a long-running check-ignore process, and for each of these
files, STDOUT will indicate whether that file matched a pattern or
not. (Without this option, it would be impossible to tell whether the
absence of output for a given file meant that it didn't match any
pattern, or that the output hadn't been generated yet.)
Buffering happens as documented under the `GIT_FLUSH` option in
linkgit:git[1]. The caller is responsible for avoiding deadlocks
caused by overfilling an input buffer or reading from an empty output
buffer.
EXIT STATUS
-----------
0::
One or more of the provided paths is ignored.
1::
None of the provided paths are ignored.
128::
A fatal error was encountered.
