Patterns 37are lists of one or more search expressions separated by newline 38characters. An empty string as search expression matches all lines. 39 40 41CONFIGURATION 42------------- 43 44grep.lineNumber:: 45 If set to true, enable `-n` option by default. 46 47grep.patternType:: 48 Set the default matching behavior. Using a value of 'basic', 'extended', 49 'fixed', or 'perl' will enable the `--basic-regexp`, `--extended-regexp`, 50 `--fixed-strings`, or `--perl-regexp` option accordingly, while the 51 value 'default' will return to the default matching behavior. 52 53grep.extendedRegexp:: 54 If set to true, enable `--extended-regexp` option by default. This 55 option is ignored when the `grep.patternType` option is set to a value 56 other than 'default'. 57 58grep.threads:: 59 Number of grep worker threads to use. If unset (or set to 0), 60 8 threads are used by default (for now). 61 62grep.fullName:: 63 If set to true, enable `--full-name` option by default. 64 65grep.fallbackToNoIndex:: 66 If set to true, fall back to git grep --no-index if git grep 67 is executed outside of a git repository. Defaults to false. 68 69 70OPTIONS 71------- 72--cached:: 73 Instead of searching tracked files in the working tree, search 74 blobs registered in the index file. 75 76--no-index:: 77 Search files in the current directory that is not managed by Git. 78 79--untracked:: 80 In addition to searching in the tracked files in the working 81 tree, search also in untracked files. 82 83--no-exclude-standard:: 84 Also search in ignored files by not honoring the `.gitignore` 85 mechanism. Only useful with `--untracked`. 86 87--exclude-standard:: 88 Do not pay attention to ignored files specified via the `.gitignore` 89 mechanism. Only useful when searching files in the current directory 90 with `--no-index`. 91 92--recurse-submodules:: 93 Recursively search in each submodule that has been initialized and 94 checked out in the repository. When used in combination with the 95 <tree> option the prefix of all submodule output will be the name of 96 the parent project's <tree> object. 97 98--parent-basename <basename>:: 99 For internal use only. In order to produce uniform output with the 100 --recurse-submodules option, this option can be used to provide the 101 basename of a parent's <tree> object to a submodule so the submodule 102 can prefix its output with the parent's name rather than the SHA1 of 103 the submodule. 104 105-a:: 106--text:: 107 Process binary files as if they were text. 108 109--textconv:: 110 Honor textconv filter settings. 111 112--no-textconv:: 113 Do not honor textconv filter settings. 114 This is the default. 115 116-i:: 117--ignore-case:: 118 Ignore case differences between the patterns and the 119 files. 120 121-I:: 122 Don't match the pattern in binary files. 123 124--max-depth <depth>:: 125 For each <pathspec> given on command line, descend at most <depth> 126 levels of directories. A negative value means no limit. 127 This option is ignored if <pathspec> contains active wildcards. 128 In other words if "a*" matches a directory named "a*", 129 "*" is matched literally so --max-depth is still effective. 130 131-w:: 132--word-regexp:: 133 Match the pattern only at word boundary (either begin at the 134 beginning of a line, or preceded by a non-word character; end at 135 the end of a line or followed by a non-word character). 136 137-v:: 138--invert-match:: 139 Select non-matching lines. 140 141-h:: 142-H:: 143 By default, the command shows the filename for each 144 match. `-h` option is used to suppress this output. 145 `-H` is there for completeness and does not do anything 146 except it overrides `-h` given earlier on the command 147 line. 148 149--full-name:: 150 When run from a subdirectory, the command usually 151 outputs paths relative to the current directory. This 152 option forces paths to be output relative to the project 153 top directory. 154 155-E:: 156--extended-regexp:: 157-G:: 158--basic-regexp:: 159 Use POSIX extended/basic regexp for patterns. Default 160 is to use basic regexp. 161 162-P:: 163--perl-regexp:: 164 Use Perl-compatible regular expressions for patterns. 165+ 166Support for these types of regular expressions is an optional 167compile-time dependency. If Git wasn't compiled with support for them 168providing this option will cause it to die. 169 170-F:: 171--fixed-strings:: 172 Use fixed strings for patterns (don't interpret pattern 173 as a regex). 174 175-n:: 176--line-number:: 177 Prefix the line number to matching lines. 178 179-l:: 180--files-with-matches:: 181--name-only:: 182-L:: 183--files-without-match:: 184 Instead of showing every matched line, show only the 185 names of files that contain (or do not contain) matches. 186 For better compatibility with 'git diff', `--name-only` is a 187 synonym for `--files-with-matches`. 188 189-O[<pager>]:: 190--open-files-in-pager[=<pager>]:: 191 Open the matching files in the pager (not the output of 'grep'). 192 If the pager happens to be "less" or "vi", and the user 193 specified only one pattern, the first file is positioned at 194 the first match automatically. The `pager` argument is 195 optional; if specified, it must be stuck to the option 196 without a space. If `pager` is unspecified, the default pager 197 will be used (see `core.pager` in linkgit:git-config[1]). 198 199-z:: 200--null:: 201 Output \0 instead of the character that normally follows a 202 file name. 203 204-c:: 205--count:: 206 Instead of showing every matched line, show the number of 207 lines that match. 208 209--color[=<when>]:: 210 Show colored matches. 211 The value must be always (the default), never, or auto. 212 213--no-color:: 214 Turn off match highlighting, even when the configuration file 215 gives the default to color output. 216 Same as `--color=never`. 217 218--break:: 219 Print an empty line between matches from different files. 220 221--heading:: 222 Show the filename above the matches in that file instead of 223 at the start of each shown line. 224 225-p:: 226--show-function:: 227 Show the preceding line that contains the function name of 228 the match, unless the matching line is a function name itself. 229 The name is determined in the same way as 'git diff' works out 230 patch hunk headers (see 'Defining a custom hunk-header' in 231 linkgit:gitattributes[5]). 232 233-<num>:: 234-C <num>:: 235--context <num>:: 236 Show <num> leading and trailing lines, and place a line 237 containing `--` between contiguous groups of matches. 238 239-A <num>:: 240--after-context <num>:: 241 Show <num> trailing lines, and place a line containing 242 `--` between contiguous groups of matches. 243 244-B <num>:: 245--before-context <num>:: 246 Show <num> leading lines, and place a line containing 247 `--` between contiguous groups of matches. 248 249-W:: 250--function-context:: 251 Show the surrounding text from the previous line containing a 252 function name up to the one before the next function name, 253 effectively showing the whole function in which the match was 254 found. 255 256--threads <num>:: 257 Number of grep worker threads to use. 258 See `grep.threads` in 'CONFIGURATION' for more information. 259 260-f <file>:: 261 Read patterns from <file>, one per line. 262 263-e:: 264 The next parameter is the pattern. This option has to be 265 used for patterns starting with `-` and should be used in 266 scripts passing user input to grep. Multiple patterns are 267 combined by 'or'. 268 269--and:: 270--or:: 271--not:: 272( ... ):: 273 Specify how multiple patterns are combined using Boolean 274 expressions. `--or` is the default operator. `--and` has 275 higher precedence than `--or`. `-e` has to be used for all 276 patterns. 277 278--all-match:: 279 When giving multiple pattern expressions combined with `--or`, 280 this flag is specified to limit the match to files that 281 have lines to match all of them. 282 283-q:: 284--quiet:: 285 Do not output matched lines; instead, exit with status 0 when 286 there is a match and with non-zero status when there isn't. 287 288<tree>...:: 289 Instead of searching tracked files in the working tree, search 290 blobs in the given trees. 291 292\--:: 293 Signals the end of options; the rest of the parameters 294 are <pathspec> limiters. 295 296<pathspec>...:: 297 If given, limit the search to paths matching at least one pattern. 298 Both leading paths match and glob(7) patterns are supported. 299 300Examples 301-------- 302 303`git grep 'time_t' -- '*.[ch]'`:: 304 Looks for `time_t` in all tracked .c and .h files in the working 305 directory and its subdirectories. 306 307`git grep -e '#define' --and \( -e MAX_PATH -e PATH_MAX \)`:: 308 Looks for a line that has `#define` and either `MAX_PATH` or 309 `PATH_MAX`. 310 311`git grep --all-match -e NODE -e Unexpected`:: 312 Looks for a line that has `NODE` or `Unexpected` in 313 files that have lines that match both. 314 315GIT 316--- 317Part of the linkgit:git[1] suite
