DESCRIPTION
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
-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.
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.
+ 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.
