grep, but only certain file extensions

Question

I am working on writing some scripts to grep certain directories, but these directories contain all sorts of file types.

I want to grep jus

Answer 1

Just use the --include parameter, like this:

grep -inr --include \*.h --include \*.cpp CP_Image ~/path[12345] | mailx -s GREP email@domain.com

that should do what you want.

To take the explanation from HoldOffHunger's answer below:

• grep: command

• -r: recursively

• -i: ignore-case

• -n: each output line is preceded by its relative line number in the file

• --include \*.cpp: all *.cpp: C++ files (escape with \ just in case you have a directory with asterisks in the filenames)

• ./: Start at current directory.
