using grep to search

Question

Hey guys I was just curious to see if someone could help me. I'm trying to search a directory recursively to find a file that has .poem as the extension and contains "I" in it.

when I do

grep -r -e --include *.poem I

I get nothing to show up

Answer 1

To return the filenames only:

 grep -r -H "I" yourdir --include *.poem | cut -d: -f1 | uniq -u

Replace yourdir by the directory.

Answer 2

grep --include "*.poem" -R I .
