Unix Command to List files containing string but *NOT* containing another string

Question

How do I recursively view a list of files that has one string and specifically doesn\'t have another string? Also, I mean to evaluate the text of the files, not the filenames.

Answer 1

Try this:

grep -rl  | xargs grep -L 

Explanation: grep -lr makes grep recursively (r) output a list (l) of all files that contain . xargs loops over these files, calling grep -L on each one of them. grep -L will only output the filename when the file does not contain .
