Tony, what’s the difference between -i and -name? I have used the -name switch a lot with success, as in:
grep ./ -name foo

Hey Scott,
I’m not sure what the difference is. I only pulled this trick out my little reference book.

-i means ignorecase

Guys,
Not all Unixes have a “grep” that supports the “-r” option.
This command is little longer but will work on any unix:
find top-dir -exec grep whatever /dev/null {} \;
