+===================
+
+NAME
+----
+git-check-ignore - Debug gitignore / exclude files
+
+
+SYNOPSIS
+--------
+[verse]
+'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::
+	Instead of printing the paths that are excluded, for each path
+	that matches an exclude pattern, print the exclude pattern
+	together with the path.  (Matching an exclude pattern usually
+	means the path is excluded, but if the pattern begins with "`!`"
+	then it is a negated pattern and matching it means the path is
+	NOT excluded.)
++
+For precedence rules within and between exclude sources, see
+linkgit: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-parsable (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
+linkgit: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.
