Not in particular. See http://perldoc.perl.org/perlipc.html for some initial 
pointers (though you should use IO::Socket and friends, etc. which I'm not 
sure if it mentions it properly). You can learn how to do IPC, and then it 
serves you for the rest of your life.

Saving to a file is a good option. However, as Ted Zlatanov mentioned in reply 
to my message, if you're doing such acrobatics to get a value from program 
being forked and ran in gnome-terminal, you should reconsider your study. 
There are much better uses for Inter-Process Communication (IPC) than what it 
seems like you're trying to do.
