Use 'grep' in conjuction with some other utility that generates the
names of the files you want to search. find(1) is ideal for this
purpose.
The easiest/simplest way I've found is to run the find in a subshell
of the grep line, e.g.:
cd /usr/src/linux
grep adaptec `find . -name *.[ch]`
This would find all *.c and *.h files underneath the Linux source
tree, and stick it on the command line automagically next to the
search term -- and grep ends up slogging through each file in
turn.
Other ways to do it involve both find and grep, and potentially
xargs as well (useful if you have a large number of files to
look through.)
