This isn't a hacker's question, so I'm sending it to -questions where
you should follow it up if need be.

Assuming that you are using either bash (yay :) or /bin/sh, all you
need to do is type it in. You'll get a secondary prompt till you type in
'done' and then your little command line will run. Here's an example of
something that I use all the time, bonus points if you can tell me what
it does. :)
bash$ for FOO in `ls /usr/local/bin/*ntp*`; do
> ln -s $FOO ${FOO##*/}

You could also type it in all on one line, but I think it's more fun to
do it a line at a time. :) It's also easier to see what's happening.
Good luck,
Doug
