I blew a few minds a week ago when I told my younger coworkers about man pages. I hit ‘em with the `man man` and one dude was like “whoa!”
Reminds me of the old canard of 'man woman'
man, cat, lynx... We're all just creatures in a vast universe
$ man -k <whatever>
Further blow their minds by showing them `apropos` https://manpages.debian.org/testing/man-db/apropos.1.en.html
