It's a pipe.
Basically, it acts just like a real pipe does in your plumbing system, but
instead of water flowing through it, data does. The pipe below connects the
output from the echo command to the gawk command.
Try this for an easy example:
Ls -al | less
The output from the ls command will be passed to the program 'less' whose
function is to display data on the screen and let you scroll up and down it.

This is a newbie list right? [okay, good] I don't want to be too
embarassed to ask a stuped question. Would someone be willing to explain
what this does? I
mean each character has significance, right? So what is it? This
reminds me of the random characters thrown up on my screen after
disconnecting from the old
BBS.

"The way I see it, there were two great triumphs, two things that
I'm proudest of. One is the economic recovery, in which the people of
America created - and filled - 19 million new jobs. The other is the
recovery of our morale. America is respected again in the world and looked
to for leadership."
