This + option forces paths to be output relative to the project + top directory. + +-E:: +--extended-regexp:: +-G:: +--basic-regexp:: + Use POSIX extended/basic regexp for patterns. Default + is to use basic regexp. + +-F:: +--fixed-strings:: + Use fixed strings for patterns (don't interpret pattern + as a regex). + +-n:: + Prefix the line number to matching lines. + +-l:: +--files-with-matches:: +--name-only:: +-L:: +--files-without-match:: + Instead of showing every matched line, show only the + names of files that contain (or do not contain) matches. + For better compatibility with 'git-diff', --name-only is a + synonym for --files-with-matches. + +-z:: +--null:: + Output \0 instead of the character that normally follows a + file name. + +-c:: +--count:: + Instead of showing every matched line, show the number of + lines that match. + +-[ABC] <context>:: + Show `context` trailing (`A` -- after), or leading (`B` + -- before), or both (`C` -- context) lines, and place a + line containing `--` between contiguous groups of + matches. + +-<num>:: + A shortcut for specifying -C<num>. + +-f <file>:: + Read patterns from <file>, one per line. + +-e:: + The next parameter is the pattern. This option has to be + used for patterns starting with - and should be used in + scripts passing user input to grep. Multiple patterns are + combined by 'or'. + +--and:: +--or:: +--not:: +( ... ):: + Specify how multiple patterns are combined using Boolean + expressions. `--or` is the default operator. `--and` has + higher precedence than `--or`. `-e` has to be used for all + patterns. + +--all-match:: + When giving multiple pattern expressions combined with `--or`, + this flag is specified to limit the match to files that + have lines to match all of them. + +`<tree>...`:: + Search blobs in the trees for specified patterns. + +\--:: + Signals the end of options; the rest of the parameters + are <path> limiters. + + +Example +------- + +git grep -e \'#define\' --and \( -e MAX_PATH -e PATH_MAX \):: + Looks for a line that has `#define` and either `MAX_PATH` or + `PATH_MAX`. + +git grep --all-match -e NODE -e Unexpected:: + Looks for a line that has `NODE` or `Unexpected` in + files that have lines that match both. + +Author +------ +Originally written by Linus Torvalds <torvalds@osdl.org>, later +revamped by Junio C Hamano. + + +Documentation +-------------- +Documentation by Junio C Hamano and the git-list <git@vger.kernel.org>. + +GIT +--- +Part of the linkgit:git[1] suite |
