1git-grep(1) 2=========== 3 4NAME 5---- 6git-grep - Print lines matching a pattern 7 8 9SYNOPSIS 10-------- 11[verse] 12'git grep' [-a | --text] [-I] [-i | --ignore-case] [-w | --word-regexp] 13 [-v | --invert-match] [-h|-H] [--full-name] 14 [-E | --extended-regexp] [-G | --basic-regexp] 15 [-F | --fixed-strings] [-n] 16 [-l | --files-with-matches] [-L | --files-without-match] 17 [(-O | --open-files-in-pager) [<pager>]] 18 [-z | --null] 19 [-c | --count] [--all-match] [-q | --quiet] 20 [--max-depth <depth>] 21 [--color[=<when>] | --no-color] 22 [-A <post-context>] [-B <pre-context>] [-C <context>] 23 [-f <file>] [-e] <pattern> 24 [--and|--or|--not|(|)|-e <pattern>...] 25 [--cached | --no-index | <tree>...] 26 [--] [<pathspec>...] 27 28DESCRIPTION 29----------- 30Look for specified patterns in the tracked files in the work tree, blobs 31registered in the index file, or blobs in given tree objects. 32 33 34OPTIONS 35------- 36--cached:: 37 Instead of searching tracked files in the working tree, search 38 blobs registered in the index file. 39 40--no-index:: 41 Search files in the current directory, not just those tracked by git. 42 43-a:: 44--text:: 45 Process binary files as if they were text. 46 47-i:: 48--ignore-case:: 49 Ignore case differences between the patterns and the 50 files. 51 52-I:: 53 Don't match the pattern in binary files. 54 55--max-depth <depth>:: 56 For each <pathspec> given on command line, descend at most <depth> 57 levels of directories. A negative value means no limit. 58 59-w:: 60--word-regexp:: 61 Match the pattern only at word boundary (either begin at the 62 beginning of a line, or preceded by a non-word character; end at 63 the end of a line or followed by a non-word character). 64 65-v:: 66--invert-match:: 67 Select non-matching lines. 68 69-h:: 70-H:: 71 By default, the command shows the filename for each 72 match. `-h` option is used to suppress this output. 73 `-H` is there for completeness and does not do anything 74 except it overrides `-h` given earlier on the command 75 line. 76 77--full-name:: 78 When run from a subdirectory, the command usually 79 outputs paths relative to the current directory. This 80 option forces paths to be output relative to the project 81 top directory. 82 83-E:: 84--extended-regexp:: 85-G:: 86--basic-regexp:: 87 Use POSIX extended/basic regexp for patterns. Default 88 is to use basic regexp. 89 90-F:: 91--fixed-strings:: 92 Use fixed strings for patterns (don't interpret pattern 93 as a regex). 94 95-n:: 96 Prefix the line number to matching lines. 97 98-l:: 99--files-with-matches:: 100--name-only:: 101-L:: 102--files-without-match:: 103 Instead of showing every matched line, show only the 104 names of files that contain (or do not contain) matches. 105 For better compatibility with 'git diff', `--name-only` is a 106 synonym for `--files-with-matches`. 107 108-O [<pager>]:: 109--open-files-in-pager [<pager>]:: 110 Open the matching files in the pager (not the output of 'grep'). 111 If the pager happens to be "less" or "vi", and the user 112 specified only one pattern, the first file is positioned at 113 the first match automatically. 114 115-z:: 116--null:: 117 Output \0 instead of the character that normally follows a 118 file name. 119 120-c:: 121--count:: 122 Instead of showing every matched line, show the number of 123 lines that match. 124 125--color[=<when>]:: 126 Show colored matches. 127 The value must be always (the default), never, or auto. 128 129--no-color:: 130 Turn off match highlighting, even when the configuration file 131 gives the default to color output. 132 Same as `--color=never`. 133 134-[ABC] <context>:: 135 Show `context` trailing (`A` -- after), or leading (`B` 136 -- before), or both (`C` -- context) lines, and place a 137 line containing `--` between contiguous groups of 138 matches. 139 140-<num>:: 141 A shortcut for specifying `-C<num>`. 142 143-p:: 144--show-function:: 145 Show the preceding line that contains the function name of 146 the match, unless the matching line is a function name itself. 147 The name is determined in the same way as 'git diff' works out 148 patch hunk headers (see 'Defining a custom hunk-header' in 149 linkgit:gitattributes[5]). 150 151-f <file>:: 152 Read patterns from <file>, one per line. 153 154-e:: 155 The next parameter is the pattern. This option has to be 156 used for patterns starting with `-` and should be used in 157 scripts passing user input to grep. Multiple patterns are 158 combined by 'or'. 159 160--and:: 161--or:: 162--not:: 163( ... ):: 164 Specify how multiple patterns are combined using Boolean 165 expressions. `--or` is the default operator. `--and` has 166 higher precedence than `--or`. `-e` has to be used for all 167 patterns. 168 169--all-match:: 170 When giving multiple pattern expressions combined with `--or`, 171 this flag is specified to limit the match to files that 172 have lines to match all of them. 173 174-q:: 175--quiet:: 176 Do not output matched lines; instead, exit with status 0 when 177 there is a match and with non-zero status when there isn't. 178 179<tree>...:: 180 Instead of searching tracked files in the working tree, search 181 blobs in the given trees. 182 183\--:: 184 Signals the end of options; the rest of the parameters 185 are <pathspec> limiters. 186 187<pathspec>...:: 188 If given, limit the search to paths matching at least one pattern. 189 Both leading paths match and glob(7) patterns are supported. 190 191Examples 192-------- 193 194git grep 'time_t' \-- '*.[ch]':: 195 Looks for `time_t` in all tracked .c and .h files in the working 196 directory and its subdirectories. 197 198git grep -e \'#define\' --and \( -e MAX_PATH -e PATH_MAX \):: 199 Looks for a line that has `#define` and either `MAX_PATH` or 200 `PATH_MAX`. 201 202git grep --all-match -e NODE -e Unexpected:: 203 Looks for a line that has `NODE` or `Unexpected` in 204 files that have lines that match both. 205 206Author 207------ 208Originally written by Linus Torvalds <torvalds@osdl.org>, later 209revamped by Junio C Hamano. 210 211 212Documentation 213-------------- 214Documentation by Junio C Hamano and the git-list <git@vger.kernel.org>. 215 216GIT 217--- 218Part of the linkgit:git[1] suite
