--cached::
Instead of searching in the working tree files, check
- the blobs registerd in the index file.
+ the blobs registered in the index file.
-a | --text::
Process binary files as if they were text.
-[ABC] <context>::
Show `context` trailing (`A` -- after), or leading (`B`
-- before), or both (`C` -- context) lines, and place a
- line containing `--` between continguous groups of
+ line containing `--` between contiguous groups of
matches.
-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.
+
`<tree>...`::
Search blobs in the trees for specified patterns.
-`--`::
+\--::
Signals the end of options; the rest of the parameters
are <path> limiters.

+-------
+
+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`.
