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--line-number:: 97 Prefix the line number to matching lines. 98 99-l:: 100--files-with-matches:: 101--name-only:: 102-L:: 103--files-without-match:: 104 Instead of showing every matched line, show only the 105 names of files that contain (or do not contain) matches. 106 For better compatibility with 'git diff', `--name-only` is a 107 synonym for `--files-with-matches`. 108 109-O [<pager>]:: 110--open-files-in-pager [<pager>]:: 111 Open the matching files in the pager (not the output of 'grep'). 112 If the pager happens to be "less" or "vi", and the user 113 specified only one pattern, the first file is positioned at 114 the first match automatically. 115 116-z:: 117--null:: 118 Output \0 instead of the character that normally follows a 119 file name. 120 121-c:: 122--count:: 123 Instead of showing every matched line, show the number of 124 lines that match. 125 126--color[=<when>]:: 127 Show colored matches. 128 The value must be always (the default), never, or auto. 129 130--no-color:: 131 Turn off match highlighting, even when the configuration file 132 gives the default to color output. 133 Same as `--color=never`. 134 135-[ABC] <context>:: 136 Show `context` trailing (`A` -- after), or leading (`B` 137 -- before), or both (`C` -- context) lines, and place a 138 line containing `--` between contiguous groups of 139 matches. 140 141-<num>:: 142 A shortcut for specifying `-C<num>`. 143 144-p:: 145--show-function:: 146 Show the preceding line that contains the function name of 147 the match, unless the matching line is a function name itself. 148 The name is determined in the same way as 'git diff' works out 149 patch hunk headers (see 'Defining a custom hunk-header' in 150 linkgit:gitattributes[5]). 151 152-f <file>:: 153 Read patterns from <file>, one per line. 154 155-e:: 156 The next parameter is the pattern. This option has to be 157 used for patterns starting with `-` and should be used in 158 scripts passing user input to grep. Multiple patterns are 159 combined by 'or'. 160 161--and:: 162--or:: 163--not:: 164( ... ):: 165 Specify how multiple patterns are combined using Boolean 166 expressions. `--or` is the default operator. `--and` has 167 higher precedence than `--or`. `-e` has to be used for all 168 patterns. 169 170--all-match:: 171 When giving multiple pattern expressions combined with `--or`, 172 this flag is specified to limit the match to files that 173 have lines to match all of them. 174 175-q:: 176--quiet:: 177 Do not output matched lines; instead, exit with status 0 when 178 there is a match and with non-zero status when there isn't. 179 180<tree>...:: 181 Instead of searching tracked files in the working tree, search 182 blobs in the given trees. 183 184\--:: 185 Signals the end of options; the rest of the parameters 186 are <pathspec> limiters. 187 188<pathspec>...:: 189 If given, limit the search to paths matching at least one pattern. 190 Both leading paths match and glob(7) patterns are supported. 191 192Examples 193-------- 194 195git grep {apostrophe}time_t{apostrophe} \-- {apostrophe}*.[ch]{apostrophe}:: 196 Looks for `time_t` in all tracked .c and .h files in the working 197 directory and its subdirectories. 198 199git grep -e {apostrophe}#define{apostrophe} --and \( -e MAX_PATH -e PATH_MAX \):: 200 Looks for a line that has `#define` and either `MAX_PATH` or 201 `PATH_MAX`. 202 203git grep --all-match -e NODE -e Unexpected:: 204 Looks for a line that has `NODE` or `Unexpected` in 205 files that have lines that match both. 206 207Author 208------ 209Originally written by Linus Torvalds <torvalds@osdl.org>, later 210revamped by Junio C Hamano. 211 212 213Documentation 214-------------- 215Documentation by Junio C Hamano and the git-list <git@vger.kernel.org>. 216 217GIT 218--- 219Part of the linkgit:git[1] suite
