You can utilize grep's PERL regexes, more specifically lookarounds, to check presence of two (or more) words. ```sh $ grep -Prn . -e '^(?=.*\bfoo\b)(?=.*\bbar\b)' ``` Here regex checks, that beginning of the line (`^`) is followed by words `foo` and `bar` somewhere in that line. Please notice, that since we are not actually matching said words, option `-w` is of no use, and we need to surround filtering words with boundary symbols. Demo of similar command online [here](https://ideone.com/Dhbm0S). Demo of regex with some additional explanation can be seen [here](https://regex101.com/r/JlB8Pv/1).
