git-check-ignore - Debug gitignore / exclude files
git check-ignore [options] pathname...
git check-ignore [options] --stdin
For each pathname given via the command-line or from a file via
--stdin, check whether the file is excluded by .gitignore (or other
input files to the exclude mechanism) and output the path if it is
By default, tracked files are not shown at all since they are not
subject to exclude rules; but see '--no-index'.
Don't output anything, just set exit status. This is only valid
with a single pathname.
Also output details about the matching pattern (if any) for each
given pathname. For precedence rules within and between exclude
sources, see gitignore(5).
Read pathnames from the standard input, one per line, instead of
from the command-line.
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.
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 look in the index when undertaking the checks. This can be
used to debug why a path became tracked by e.g. git add . and was
not ignored by the rules as expected by the user or when developing
patterns including negation to match a path previously added with
git add -f.
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
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 git(1).
The caller is responsible for avoiding deadlocks caused by overfilling
an input buffer or reading from an empty output buffer.
One or more of the provided paths is ignored.
None of the provided paths are ignored.
A fatal error was encountered.
