Scripting keyboard input with Ruby

Question

I'm hoping to write a script that can control GNU Screen for example split the screen with 'Ctrl + S'. My ultimate objective is to run 4 different applications with a single script. Is this possible within Ruby?

Thanks!

I doubt there is any key capture library out there. You can try to write it in C and wrap up — SwiftMango

You can do this without too much difficulty in JRuby, since Java can do this. Alternatively, I've done this sort of thing with Sikuli, a very impressive Jython framework for doing this sort of thing, complete with screenshot analysis for determining where to click. Posting as a comment because I'm too tired to do the research to make a proper answer with an example. — Joshua Cheek

I haven't found any pre-made Ruby solution, but there are various pages about doing it with shell commands. For example, Scripting screen for fun and profit.
