Linux optimize  Power Linux with pipes and redirection  Despite
the fact that most people consider command-line computer use a
thing of the past, there are some really interesting things you
can do with the command-line. Despite pretty GUIs and eye candy
being the order of the day, there is a definite advantage to
being familiar and comfortable with the Linux command-line.  Two
such advantages are the use of pipes and redirection. With pipes
and redirection, you can "chain" multiple programs to become
