Saying Yes

Tired of being prompted for confirmation by command-line utilities? Wish you could blindly respond 'yes' to whatever it is they are bugging you about? The yes command is what you've been looking for.

$ yes | rm -r ~/some/dir

This will respond y as rm asks for confirmation on removing each and every file in that directory.

yes is just as good at saying no. Give it no as an argument and it will happily (and endlessly) print no.

$ yes no
