Search for text string in files

["Chuckk Hubbard" <badmuthahubbard@gmail.com>]

Can you do this?  I still can't find out why 2 instances of the jack
audio connection kit are starting up on boot, and I find myself
opening each startup script and searching for "jack".  If there's a
better way, Google doesn't have access to it.  Is there a command I
can type that will search for a string in all files within a
directory?
Thanks.
