Long for a pop-up Terminal to appear at the push of a button? Well, you got it with VTerminal.
Quickly and easily run any type of program/executable/script on Ubuntu using the small open source utility 'App Runner'. The tool disbands with the need to mark a file as "executable" before running, allowing you to run an installer, application, script or other OS supported executable automatically.
