A lot of people find "alternatives" to the OS X apps, but they don't realize the difference is so huge it's not even funny. Alfred DOES NOT have an alternative on any platform. It's so good it's unbelievable, takes job of multiple programs I need to constantly use on Linux. Also DashDoc, etc. Also there is Terminator yes, but it's feature set is nowhere near of iTerm2, it's crazy what you can do with it and how convenient is it compared to any terminal emulators.
