Don't make me google "sudo". What are these things.
The command 'touch' checks to see if there is a file with that name and if it doesn't exist, then it creates it. Therefore, 'touch myself' will make a file named 'myself' unless it already exists.

'w' is the shortest command I know. It is short for 'who' and it checks who is logged into the computer.

'sudo' means temporarily log me in as the administrator to run this one command so that I have elevated privileges. 'cat' takes a file and writes it to your screen. 'dev/random' is a device on your computer that spits out random numbers continuously. So 'cat /dev/urandom' means write every random number there is to my screen. '>' means take the output of the command before this and send it to the following place. 'dev/dsp' are the speakers in a file format. So "cat /dev/urandom > /dev/dsp" means take every random number and then send them to the speakers. The sound from this is worse than 1,000 dial up modems all signing on at once.

'sudo rm -rf /*' is the worst one ever. It essential means remove (rm) recursively and forcefully (-rf) every file under '/' (/*) and for those of you who know what '/' is, it's the top directory for EVERY FILE ON YOUR COMPUTER. So it will delete everything while having admin rights to delete any file it wants.

superuser do (a command)

there is a well-known (among geeks) cartoon where a guy says to his girlfriend, "make me a sandwich" and she says, "make your own damn sandwich" then he says, "sudo make me a sandwich" and she does it
