I know in Windows it's a .EXE, what about Ubuntu? Specifically I removed the startup application hook for Docky and for whatever reason Docky won't add it back in, so I want to add it back in manually. However I'm not sure what file I am looking for here... So that brought me to this question, in general what file type am I looking for that is 'executable' in Ubuntu for this purpose?
I'm assuming there could be many files, or it might not be files at all.. I'm still shedding off my Windows-esque thinking mode, please help :)
