GIT-CHECK-IGNORE(1)               Git Manual               GIT-CHECK-IGNORE(1)

NAME
       git-check-ignore - Debug gitignore / exclude files

SYNOPSIS
       git check-ignore [options] pathname...
       git check-ignore [options] --stdin

DESCRIPTION
       For each pathname given via the command-line or from a file via
       --stdin, check whether the file is excluded by .gitignore (or other
       input files to the exclude mechanism) and output the path if it is
       excluded.

       By default, tracked files are not shown at all since they are not
       subject to exclude rules; but see '--no-index'.

OPTIONS
       -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. For precedence rules within and between exclude
           sources, see gitignore(5).

       --stdin
           Read pathnames from the standard input, one per line, instead of
           from the command-line.

       -z
           The output format is modified to be machine-parseable (see below).
           If --stdin is 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 --verbose is enabled, otherwise it would not be possible
           to distinguish between paths which match a pattern and those which
           don't.

       --no-index
           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.

OUTPUT
       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.

       If --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
       contained a ! prefix or / suffix, it will be preserved in the output.
       <source> will be an absolute path when referring to the file configured
       by core.excludesFile, or relative to the repository root when referring
       to .git/info/exclude or a per-directory exclude file.

       If -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>

       If -n or --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(1).
       The caller is responsible for avoiding deadlocks caused by overfilling
       an input buffer or reading from an empty output buffer.

EXIT STATUS
       0
           One or more of the provided paths is ignored.

       1
           None of the provided paths are ignored.

       128
           A fatal error was encountered.
