I see...
 
Thanks for the info on the > /dev/null & part. That will be useful... how is that related to the | (pipe), which allows the piping of output as in tar -tf linux-2.4.18.tar.gz|egrep kde?

I see your point about the tips, acid_kewpie. This is a general problem I have with putting too much effort into forum posts. :p

| is used to redirect SDTOUT into SDTIN of another program.

Also useful is the < , which is used to read a file as STDIN for a process... This often gets neglected in favor of cat however.

Almost everywhere you see:
cat filename | someprogram

Can be re-written as:
someprogram < filename

/dev/null is... also a great device to use for backups. Guaranteed, backups will go many times faster.
Uh-oh, someone's been reading The BOFH again!
