I frequently use find - grep when looking at a novel source tree. The one
problem with the solution given is that if you are looking for a few
instances in hundreds of files, the hits can scroll off the screen and get
lost in the noise. My prefered approach is:
find . -name "*.[c]" -exec grep string {} /dev/null \;
(the /dev/null forces grep to print the filename where a match is found,
and I am an old fogey, learned grep before [ef]grep too lazy to learn
better, should probably use fgrep)
What I'd really like to see is a free implementation of cscope.
