Hmm. I type Alt-F2 and I get.... nadda. I guess you are using KDE, so that must be a KDE-specific command.
I want to start/excute perl file on a new terminal every time.
Every what time? Every time your system boots? Every time you log in? Every time you start a new terminal? Any of these are possible, but you need to explain which. In general, come right out and say what you're trying to accomplish. A lot of us here don't speak Windows, so it isn't the best way to describe your objective.
