How to combine "find" command in for each loop (tcsh)

Hello
I was wandering if I can combine find command in side for each loop in unix
the main propose is to change some thing in files from several types and not all of them
is this possible ? (on liner script? )

tnx for the helppers

#!/usr/bin/ksh
for i in `find $PATH your filter conditions`
do
.... do whatever you want to do with $i
done

I m giving an example for ksh. As such no idea of tcsh should work to my belief.

#!/usr/bin/ksh
for i in `find $PATH filter conditions`
do
....
do whatever you want with $i
done

regards,
Rishi
