I don't use either myself but I'm in a position where I get to see what it produces for other people. Here's a recent (2-3 months old) example: A zsh script that immediately invoked a Python interpreter that immediately invoked a shell command and iterated over each line of output looking for one of a few strings to match... So, `<cmd> | grep "(stringA|stringB|stringC)"`, but a whole lot dumber.

Thanks, but no thanks, I don't need that kind of code in anything I'm working with.
