# List Names Of Files With Matches

I often use `grep` and `ag` to search for patterns in a group or directory
of files. Generally I am interested in looking at the matching lines
themselves. However, sometimes I just want to know the set of files that
have matches. Both `grep` and `ag` can be told to output nothing more than
the names of the files with matches when given the `-l` flag.

This can come in particularly handy if you just want a list of files that
can be piped (or copied) for use with another command. This eliminates all
the extra noise.
