6 git-check-ignore - Debug gitignore / exclude files
12 'git check-ignore' [options] pathname...
13 'git check-ignore' [options] --stdin < <list-of-paths>
18 For each pathname given via the command-line or from a file via
19 `--stdin`, show the pattern from .gitignore (or other input files to
20 the exclude mechanism) that decides if the pathname is excluded or
21 included. Later patterns within a file take precedence over earlier
27 Don't output anything, just set exit status. This is only
28 valid with a single pathname.
31 Also output details about the matching pattern (if any)
32 for each given pathname.
35 Read file names from stdin instead of from the command-line.
38 The output format is modified to be machine-parseable (see
39 below). If `--stdin` is also given, input paths are separated
40 with a NUL character instead of a linefeed character.
43 Show given paths which don't match any pattern. This only
44 makes sense when `--verbose` is enabled, otherwise it would
45 not be possible to distinguish between paths which match a
46 pattern and those which don't.
49 Don't look in the index when undertaking the checks. This can
50 be used to debug why a path became tracked by e.g. `git add .`
51 and was not ignored by the rules as expected by the user or when
52 developing patterns including negation to match a path previously
53 added with `git add -f`.
58 By default, any of the given pathnames which match an ignore pattern
59 will be output, one per line. If no pattern matches a given path,
60 nothing will be output for that path; this means that path will not be
63 If `--verbose` is specified, the output is a series of lines of the form:
65 <source> <COLON> <linenum> <COLON> <pattern> <HT> <pathname>
67 <pathname> is the path of a file being queried, <pattern> is the
68 matching pattern, <source> is the pattern's source file, and <linenum>
69 is the line number of the pattern within that source. If the pattern
70 contained a `!` prefix or `/` suffix, it will be preserved in the
71 output. <source> will be an absolute path when referring to the file
72 configured by `core.excludesfile`, or relative to the repository root
73 when referring to `.git/info/exclude` or a per-directory exclude file.
75 If `-z` is specified, the pathnames in the output are delimited by the
76 null character; if `--verbose` is also specified then null characters
77 are also used instead of colons and hard tabs:
79 <source> <NULL> <linenum> <NULL> <pattern> <NULL> <pathname> <NULL>
81 If `-n` or `--non-matching` are specified, non-matching pathnames will
82 also be output, in which case all fields in each output record except
83 for <pathname> will be empty. This can be useful when running
84 non-interactively, so that files can be incrementally streamed to
85 STDIN of a long-running check-ignore process, and for each of these
86 files, STDOUT will indicate whether that file matched a pattern or
87 not. (Without this option, it would be impossible to tell whether the
88 absence of output for a given file meant that it didn't match any
89 pattern, or that the output hadn't been generated yet.)
91 Buffering happens as documented under the `GIT_FLUSH` option in
92 linkgit:git[1]. The caller is responsible for avoiding deadlocks
93 caused by overfilling an input buffer or reading from an empty output
100 One or more of the provided paths is ignored.
103 None of the provided paths are ignored.
