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 < <list-of-paths> DESCRIPTION
For each pathname given via the command-line or from a file via --stdin, show the pattern from .gitignore (or other input files to the exclude mechanism) that decides if the pathname is excluded or included. Later patterns within a file take precedence over earlier ones. 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. --stdin Read file names from stdin 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. 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> 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. SEE ALSO
