6 git-check-ignore - Debug gitignore / exclude files
12 'git check-ignore' [<options>] <pathname>...
13 'git check-ignore' [<options>] --stdin
18 For each pathname given via the command-line or from a file via
19 `--stdin`, check whether the file is excluded by .gitignore (or other
20 input files to the exclude mechanism) and output the path if it is
23 By default, tracked files are not shown at all since they are not
24 subject to exclude rules; but see `--no-index'.
29 Don't output anything, just set exit status. This is only
30 valid with a single pathname.
33 Instead of printing the paths that are excluded, for each path
34 that matches an exclude pattern, print the exclude pattern
35 together with the path. (Matching an exclude pattern usually
36 means the path is excluded, but if the pattern begins with '!'
37 then it is a negated pattern and matching it means the path is
40 For precedence rules within and between exclude sources, see
44 Read pathnames from the standard input, one per line,
45 instead of from the command-line.
48 The output format is modified to be machine-parsable (see
49 below). If `--stdin` is also given, input paths are separated
50 with a NUL character instead of a linefeed character.
53 Show given paths which don't match any pattern. This only
54 makes sense when `--verbose` is enabled, otherwise it would
55 not be possible to distinguish between paths which match a
56 pattern and those which don't.
59 Don't look in the index when undertaking the checks. This can
60 be used to debug why a path became tracked by e.g. `git add .`
61 and was not ignored by the rules as expected by the user or when
62 developing patterns including negation to match a path previously
63 added with `git add -f`.
68 By default, any of the given pathnames which match an ignore pattern
69 will be output, one per line. If no pattern matches a given path,
70 nothing will be output for that path; this means that path will not be
73 If `--verbose` is specified, the output is a series of lines of the form:
75 <source> <COLON> <linenum> <COLON> <pattern> <HT> <pathname>
77 <pathname> is the path of a file being queried, <pattern> is the
78 matching pattern, <source> is the pattern's source file, and <linenum>
79 is the line number of the pattern within that source. If the pattern
80 contained a `!` prefix or `/` suffix, it will be preserved in the
81 output. <source> will be an absolute path when referring to the file
82 configured by `core.excludesFile`, or relative to the repository root
83 when referring to `.git/info/exclude` or a per-directory exclude file.
85 If `-z` is specified, the pathnames in the output are delimited by the
86 null character; if `--verbose` is also specified then null characters
87 are also used instead of colons and hard tabs:
89 <source> <NULL> <linenum> <NULL> <pattern> <NULL> <pathname> <NULL>
91 If `-n` or `--non-matching` are specified, non-matching pathnames will
92 also be output, in which case all fields in each output record except
93 for <pathname> will be empty. This can be useful when running
94 non-interactively, so that files can be incrementally streamed to
95 STDIN of a long-running check-ignore process, and for each of these
96 files, STDOUT will indicate whether that file matched a pattern or
97 not. (Without this option, it would be impossible to tell whether the
98 absence of output for a given file meant that it didn't match any
99 pattern, or that the output hadn't been generated yet.)
101 Buffering happens as documented under the `GIT_FLUSH` option in
102 linkgit:git[1]. The caller is responsible for avoiding deadlocks
103 caused by overfilling an input buffer or reading from an empty output
110 One or more of the provided paths is ignored.
113 None of the provided paths are ignored.
