The vertical bar also called the pipe is a special shell character which basically means the standard output of the previous command becomes the standard input of the next command. The tee(1) utility reads the standard input and outputs to a file (named on the command line) and also again to standard output. tee(1) is very useful. I use it so I can see what I am doing while saving the results at the same time.
