Would you like to play a game?
NetBSD used to ship a 'falken' login that runs /usr/games/wargames
by default. That login's gone, and I've learned another reason
for this today: Apparently you can run every program from /usr/games
from it, by simply typing its name:
miyu% /usr/games/wargames
Would you like to play a game? fortune
Flying saucers on occasion
Show themselves to human eyes.
Aliens fume, put off invasion
While they brand these tales as lies.
miyu%
This reminds me of a few of the rather nifty examples in
Ivan Sklyarov's "Puzzles for Hackers", where you have to modify
a (MS-DOS) binary to do something else than printing some dull text.
Very nice examples (including detailled explanations) for doing evil stuff... recommended reading! :)
