1git-grep(1) 2=========== 3 4NAME 5---- 6git-grep - Print lines matching a pattern 7 8 9SYNOPSIS 10-------- 11[verse] 12'git grep' [--cached] 13 [-a | --text] [-I] [-i | --ignore-case] [-w | --word-regexp] 14 [-v | --invert-match] [-h|-H] [--full-name] 15 [-E | --extended-regexp] [-G | --basic-regexp] 16 [-F | --fixed-strings] [-n] 17 [-l | --files-with-matches] [-L | --files-without-match] 18 [-z | --null] 19 [-c | --count] [--all-match] [-q | --quiet] 20 [--max-depth <depth>] 21 [--color | --no-color] 22 [-A <post-context>] [-B <pre-context>] [-C <context>] 23 [-f <file>] [-e] <pattern> 24 [--and|--or|--not|(|)|-e <pattern>...] [<tree>...] 25 [--] [<path>...] 26 27DESCRIPTION 28----------- 29Look for specified patterns in the working tree files, blobs 30registered in the index file, or given tree objects. 31 32 33OPTIONS 34------- 35--cached:: 36 Instead of searching in the working tree files, check 37 the blobs registered in the index file. 38 39-a:: 40--text:: 41 Process binary files as if they were text. 42 43-i:: 44--ignore-case:: 45 Ignore case differences between the patterns and the 46 files. 47 48-I:: 49 Don't match the pattern in binary files. 50 51--max-depth <depth>:: 52 For each pathspec given on command line, descend at most <depth> 53 levels of directories. A negative value means no limit. 54 55-w:: 56--word-regexp:: 57 Match the pattern only at word boundary (either begin at the 58 beginning of a line, or preceded by a non-word character; end at 59 the end of a line or followed by a non-word character). 60 61-v:: 62--invert-match:: 63 Select non-matching lines. 64 65-h:: 66-H:: 67 By default, the command shows the filename for each 68 match. `-h` option is used to suppress this output. 69 `-H` is there for completeness and does not do anything 70 except it overrides `-h` given earlier on the command 71 line. 72 73--full-name:: 74 When run from a subdirectory, the command usually 75 outputs paths relative to the current directory. This 76 option forces paths to be output relative to the project 77 top directory. 78 79-E:: 80--extended-regexp:: 81-G:: 82--basic-regexp:: 83 Use POSIX extended/basic regexp for patterns. Default 84 is to use basic regexp. 85 86-F:: 87--fixed-strings:: 88 Use fixed strings for patterns (don't interpret pattern 89 as a regex). 90 91-n:: 92 Prefix the line number to matching lines. 93 94-l:: 95--files-with-matches:: 96--name-only:: 97-L:: 98--files-without-match:: 99 Instead of showing every matched line, show only the 100 names of files that contain (or do not contain) matches. 101 For better compatibility with 'git diff', --name-only is a 102 synonym for --files-with-matches. 103 104-z:: 105--null:: 106 Output \0 instead of the character that normally follows a 107 file name. 108 109-c:: 110--count:: 111 Instead of showing every matched line, show the number of 112 lines that match. 113 114--color:: 115 Show colored matches. 116 117--no-color:: 118 Turn off match highlighting, even when the configuration file 119 gives the default to color output. 120 121-[ABC] <context>:: 122 Show `context` trailing (`A` -- after), or leading (`B` 123 -- before), or both (`C` -- context) lines, and place a 124 line containing `--` between contiguous groups of 125 matches. 126 127-<num>:: 128 A shortcut for specifying -C<num>. 129 130-p:: 131--show-function:: 132 Show the preceding line that contains the function name of 133 the match, unless the matching line is a function name itself. 134 The name is determined in the same way as 'git diff' works out 135 patch hunk headers (see 'Defining a custom hunk-header' in 136 linkgit:gitattributes[5]). 137 138-f <file>:: 139 Read patterns from <file>, one per line. 140 141-e:: 142 The next parameter is the pattern. This option has to be 143 used for patterns starting with - and should be used in 144 scripts passing user input to grep. Multiple patterns are 145 combined by 'or'. 146 147--and:: 148--or:: 149--not:: 150( ... ):: 151 Specify how multiple patterns are combined using Boolean 152 expressions. `--or` is the default operator. `--and` has 153 higher precedence than `--or`. `-e` has to be used for all 154 patterns. 155 156--all-match:: 157 When giving multiple pattern expressions combined with `--or`, 158 this flag is specified to limit the match to files that 159 have lines to match all of them. 160 161-q:: 162--quiet:: 163 Do not output matched lines; instead, exit with status 0 when 164 there is a match and with non-zero status when there isn't. 165 166`<tree>...`:: 167 Search blobs in the trees for specified patterns. 168 169\--:: 170 Signals the end of options; the rest of the parameters 171 are <path> limiters. 172 173 174Example 175------- 176 177git grep -e \'#define\' --and \( -e MAX_PATH -e PATH_MAX \):: 178 Looks for a line that has `#define` and either `MAX_PATH` or 179 `PATH_MAX`. 180 181git grep --all-match -e NODE -e Unexpected:: 182 Looks for a line that has `NODE` or `Unexpected` in 183 files that have lines that match both. 184 185Author 186------ 187Originally written by Linus Torvalds <torvalds@osdl.org>, later 188revamped by Junio C Hamano. 189 190 191Documentation 192-------------- 193Documentation by Junio C Hamano and the git-list <git@vger.kernel.org>. 194 195GIT 196--- 197Part of the linkgit:git[1] suite
