Hello All,

I want to be able to take the files I found with my first grep statement, something like this for example: grep -r Makefile * And then pass the files found in that pass of grep to a second grep with something like this for example: grep {files} '-lfoo'

How do I do this? I know there must be a way.

Thank you.
