I was wondering how to find all the files under a directory whose contents contain any of several strings word1, word2, word3, ...?

you can do cd directory ; grep -rEl "pattern1|pattern2|pattern3" depending on your needs it can just do the job. works fine with gnugrep

Use grep’s recursive search with multiple patterns:
grep -r -F -e word1 -e word2 -e word3
If you have many words to search for, store them in a file, one per line, and give that to grep:
grep -r -F -f patternfile
Add -l in both cases if you’re only interested in the files’ names, -R (instead of -r) if you want to dereference symlinks as you go down directory tree.
How to grep thousands of files in a directory for hundreds of strings in a file has tips for doing this over large numbers of files with large numbers of patterns.

doing this way can make huge output when many patterns appear in many files on many lines each ... add -l option will only display the filenames to avoid that :)

Which one is better, your command using-e, orgrep -rEl "pattern1|pattern2|pattern3"?

-Ftellsgrepto treat the patterns as fixed strings rather than regular expressions. It is often significantly faster to use this; in my tests, searching for two patterns in 36,088 files occupying 6.3GiB (all in cache), thegrep -rFl -e ...variant is 10× faster than thegrep -rEl ...variant.
