Through the ~/.screenrc file, one may specify how many 'screens' to open when the application is started; this includes an opening command to execute.

I usually don't cheerlead particular utilities, but screen has become one of my most used tools.

A bigger selling point is that it facilitates persistent terminal sessions; in otherwords, you can detach and reattach to screen session, so you never really have to close any thing you're doing. I works *really* well if you do things on multiple remote hosts.

You'll never have to stop a compile or log off of irc again if you have a screen session going on a trusted box somewhere (aka, bounce box) - when it's time to go home, you detach. Later when you want to work on things again, login to your bounce box and reattach to the session. It'll be as if you never left.

If you need a sample ~/.screenrc, let me know off-list.
