Interesting Linux oddities
Linux has had quite a few odd programs and oddities released for it. One was a process management system that used a modified copy of Xdoom, a Doom source port, to manage processes. The utility used the Doom2 game files and there were Imps in the main outside courtyard. Shooting them and injuring the monsters would renice the process. Killing a monster would kill that process. But if the user wanted to kill a process owned by the superuser, they would therefore need root privileges. This is a very nice program for managing system processes though. Much more fun than ps. Here is the web page about this interesting utility/game.
Linux shellshock bash bug. This still works with the latest bash shell release in 2017.

The shuf command for Linux allows shuffling an array of input randomly.
jason@darkstar:~$ shuf -i 1-14 3 2 11 8 12 4 13 6 9 1 14 5 10 7
Or select a few random numbers out of a large selection.
jason@darkstar:~$ shuf -n 8 -i 14245656-19476889 16546311 16890254 14664012 17313935 14421373 16631832 17694664 17100759
