Use git-grep: http://linux.die.net/man/1/git-grep

For example, to find the definition of the function sum you may want
to use the following command:

  $ git grep -ni "def sum" *

The switch "-n" will make git-grep show the line number of the match,
while the switch "-i" will allow case-insensitive matches.

You may as well use the grep command directly (
http://linux.die.net/man/1/grep )
