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
24 By default, tracked files are not shown at all since they are not
25 subject to exclude rules; but see `--no-index'.
30 Don't output anything, just set exit status. This is only
31 valid with a single pathname.
34 Also output details about the matching pattern (if any)
35 for each given pathname.
38 Read file names from stdin instead of from the command-line.
41 The output format is modified to be machine-parseable (see
42 below). If `--stdin` is also given, input paths are separated
43 with a NUL character instead of a linefeed character.
46 Show given paths which don't match any pattern. This only
47 makes sense when `--verbose` is enabled, otherwise it would
48 not be possible to distinguish between paths which match a
49 pattern and those which don't.
52 Don't look in the index when undertaking the checks. This can
53 be used to debug why a path became tracked by e.g. `git add .`
54 and was not ignored by the rules as expected by the user or when
55 developing patterns including negation to match a path previously
56 added with `git add -f`.
61 By default, any of the given pathnames which match an ignore pattern
62 will be output, one per line. If no pattern matches a given path,
63 nothing will be output for that path; this means that path will not be
66 If `--verbose` is specified, the output is a series of lines of the form:
68 <source> <COLON> <linenum> <COLON> <pattern> <HT> <pathname>
70 <pathname> is the path of a file being queried, <pattern> is the
71 matching pattern, <source> is the pattern's source file, and <linenum>
72 is the line number of the pattern within that source. If the pattern
73 contained a `!` prefix or `/` suffix, it will be preserved in the
74 output. <source> will be an absolute path when referring to the file
75 configured by `core.excludesFile`, or relative to the repository root
76 when referring to `.git/info/exclude` or a per-directory exclude file.
78 If `-z` is specified, the pathnames in the output are delimited by the
79 null character; if `--verbose` is also specified then null characters
80 are also used instead of colons and hard tabs:
82 <source> <NULL> <linenum> <NULL> <pattern> <NULL> <pathname> <NULL>
84 If `-n` or `--non-matching` are specified, non-matching pathnames will
85 also be output, in which case all fields in each output record except
86 for <pathname> will be empty. This can be useful when running
87 non-interactively, so that files can be incrementally streamed to
88 STDIN of a long-running check-ignore process, and for each of these
89 files, STDOUT will indicate whether that file matched a pattern or
90 not. (Without this option, it would be impossible to tell whether the
91 absence of output for a given file meant that it didn't match any
92 pattern, or that the output hadn't been generated yet.)
94 Buffering happens as documented under the `GIT_FLUSH` option in
95 linkgit:git[1]. The caller is responsible for avoiding deadlocks
96 caused by overfilling an input buffer or reading from an empty output
103 One or more of the provided paths is ignored.
106 None of the provided paths are ignored.
