It's worth to read the manual pages of grep, find and xargs. For a more detailed explanation of the find utility, please take a look at http://www.gnu.org/software/findutil...mono/find.html.

Regarding your issue, you can find all the *.c files recursively, starting from the current working directory, by means of

Code:

find . -name \*.c

and to pass the list of files to the grep command, you can try xargs as in

Code:

find . -name \*.c | xargs grep PATTERN

Or you can run this in the directory containing the source files:

Code:

grep -Rn PATTERN

If you want to search in c source code, it would be easier to use "cscope". Its a free software and should be available in the repo of your distro.
