I will start making a list for linux then.

rm - ok for all ages.

grep - 18+, you can obviously use this to search for porn.

find - 18+, see grep.

reboot - ok for all ages.

echo - ok for all ages.

cat - 18+, prints the porn you found directly to your terminal.

sudo - 18+, obviously.

kill - ok for all ages. This is the US, right.

ps - 18+, no peeping at other processes.
