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
By default, tracked files are not shown at all since they are not subject to exclude rules; but see ‘--no-index’.
- -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.
Read file names from stdin instead of from the command-line.
The output format is modified to be machine-parseable (see below). If
--stdinis 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
--verboseis enabled, otherwise it would not be possible to distinguish between paths which match a pattern and those which don’t.
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 ignored.
--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
! prefix or
/ suffix, it will be preserved in the
output. <source> will be an absolute path when referring to the file
core.excludesFile, or relative to the repository root
when referring to
.git/info/exclude or a per-directory exclude file.
-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>
--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. The caller is responsible for avoiding deadlocks
caused by overfilling an input buffer or reading from an empty output
