how to use the unix “find” command to find all the cpp and h files?

Question

I know that to find all the .h files I need to use:

find . -name \"*.h\"

but how to find all the .h AND .cpp

Answer 1

A short, clear way to do it with find is:

find . -regex '.*\.\(cpp\|h\)'

From the man page for -regex: "This is a match on the whole path, not a search." Hence the need to prefix with .* to match the beginning of the path ./dir1/dir2/... before the filename.
