A command for managing arguments to other commands...
xargs is your friend. Using xargs, you can pull off feats of greatness and not have to write a script to do it. xargs can take care of things right on the command line. Though I focus mainly on files in this article (it's what I use it for almost exclusively), it's important to remember that xargs acts on standard input, which could mean lines redirected from /var/log/messages or urls or whatever else you can manage to point in its direction.
