[TriLUG] Cool Linux phone, and grep question

[Tim Jowers]

Check out this OpenSource phone:

I need to get one to play with in the near future. I hope this will succeed
more than J2ME has so far.

Oh yeah,

Does grep have a recursive AND file match option? How can I do a recursive
grep on .c files?

# grep "schedule" -R *.c
grep: *.c: No such file or directory

So far I'm doing:
grep "schedule(" -R * | grep ".c"
or
find . -name '*.c' | xargs grep "schedule("

Am I missing something with grep?
