  15DESCRIPTION
  16-----------
  17
  18For each pathname given via the command-line or from a file via
  19`--stdin`, show the pattern from .gitignore (or other input files to
  20the exclude mechanism) that decides if the pathname is excluded or
  21included.  Later patterns within a file take precedence over earlier
  22ones.
  23
  24OPTIONS
  25-------
  26-q, --quiet::
  27        Don't output anything, just set exit status.  This is only
  28        valid with a single pathname.
  29
  30-v, --verbose::
  31        Also output details about the matching pattern (if any)
  32        for each given pathname.
  33
  34--stdin::
  35        Read file names from stdin instead of from the command-line.
  36
  37-z::
  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.
  41
  42-n, --non-matching::
  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.
  47
  48OUTPUT
  49------
  50
  51By default, any of the given pathnames which match an ignore pattern
  52will be output, one per line.  If no pattern matches a given path,
  53nothing will be output for that path; this means that path will not be
  54ignored.
  55
  56If `--verbose` is specified, the output is a series of lines of the form:
  57
  58<source> <COLON> <linenum> <COLON> <pattern> <HT> <pathname>
  59
  60<pathname> is the path of a file being queried, <pattern> is the
  61matching pattern, <source> is the pattern's source file, and <linenum>
  62is the line number of the pattern within that source.  If the pattern
  63contained a `!` prefix or `/` suffix, it will be preserved in the
  64output.  <source> will be an absolute path when referring to the file
  65configured by `core.excludesfile`, or relative to the repository root
  66when referring to `.git/info/exclude` or a per-directory exclude file.
  67
  68If `-z` is specified, the pathnames in the output are delimited by the
  69null character; if `--verbose` is also specified then null characters
  70are also used instead of colons and hard tabs:
  71
  72<source> <NULL> <linenum> <NULL> <pattern> <NULL> <pathname> <NULL>
  73
  74If `-n` or `--non-matching` are specified, non-matching pathnames will
  75also be output, in which case all fields in each output record except
  76for <pathname> will be empty.  This can be useful when running
  77non-interactively, so that files can be incrementally streamed to
  78STDIN of a long-running check-ignore process, and for each of these
  79files, STDOUT will indicate whether that file matched a pattern or
  80not.  (Without this option, it would be impossible to tell whether the
  81absence of output for a given file meant that it didn't match any
  82pattern, or that the output hadn't been generated yet.)
  83
  84Buffering happens as documented under the `GIT_FLUSH` option in
  85linkgit:git[1].  The caller is responsible for avoiding deadlocks
  86caused by overfilling an input buffer or reading from an empty output
  87buffer.
  88
  89EXIT STATUS
  90-----------
  91
  920::
  93        One or more of the provided paths is ignored.
  94
  951::
  96        None of the provided paths are ignored.
  97
  98128::
  99        A fatal error was encountered.
