DESCRIPTION |
|
----------- |
|
Look for specified patterns in the working tree files, blobs |
|
registered in the index file, or given tree objects. |
|
|
|
|
|
OPTIONS |
|
------- |
|
--cached:: |
|
Instead of searching in the working tree files, check |
|
the blobs registered in the index file. |
|
|
|
-a:: |
|
--text:: |
|
Process binary files as if they were text. |
|
|
|
-i:: |
|
--ignore-case:: |
|
Ignore case differences between the patterns and the |
|
files. |
|
|
|
-I:: |
|
Don't match the pattern in binary files. |
|
|
|
-w:: |
|
--word-regexp:: |
|
Match the pattern only at word boundary (either begin at the |
|
beginning of a line, or preceded by a non-word character; end at |
|
the end of a line or followed by a non-word character). |
|
|
|
-v:: |
|
--invert-match:: |
|
Select non-matching lines. |
|
|
|
-h:: |
|
-H:: |
|
By default, the command shows the filename for each |
|
match. `-h` option is used to suppress this output. |
|
`-H` is there for completeness and does not do anything |
|
except it overrides `-h` given earlier on the command |
|
line. |
|
|
|
--full-name:: |
|
When run from a subdirectory, the command usually |
|
outputs paths relative to the current directory. 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. |
|
|
|
-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. |
