I would be very cautious about using shuf for password generation, since it doesn't use a cryptographically-secure random number generator (I just checked the source). Edit: I see that shuf permits the use of custom seeds, so you can do the following, and it will be secure: shuf -n 5 --random-source=/dev/urandom /usr/share/dict/words
