More likely I just don't know what I'm talking about. I must have been thinking about something else (shell globbing perhaps). Certainly most of the times I've seen grep used, it's to look for a word with no special metacharacters, as you say. Still a valid RE of course. But I have learned to night I don't need to resort to grep -e to use regular expressions. At least with GNU grep, that's the default. -- https://mail.python.org/mailman/listinfo/python-list
