Today, the XKCD webcomic page goes black as it simulates a Linux shell.
Here are a few things you might want to try:
`$ make me a sandwich
$ sudo make me a sandwich
$ shutdown
$ sudo shutdown
$ help
$ cheat
$ quit
$ wget http://google.com
$ man
$ cat
$ man cat
$ look
$ go south
$ light lamp`
or my favorite (from Internet Explorer):
$ sudo apt-get upgrade
Bunches of other fun commands :) You don’t have to be much of a hacker to find them all. Just a little bit of one.
