I've been a gnome2 user for a while now and have been trying various environments (e.g., kde, mate, xfce, LDE, etc) and frequently find myself launching the wrong commands for major applications (and then wasting time trying to remember what gedit is called in mate).

Is there any linux package that say can tell if I try to run gedit on MATE (and its uninstalled) and then does a command-not-found type lookup goes to a table of rough-equivalents and then runs the closest program that's installed (maybe with a brief pop-up message saying 'gedit is not installed; using closest match pluma'). E.g., gedit (gnome2) equivalents would be pluma (Mate); mousepad (xfce); kwrite or kate (kde), leafpad (lxde), xedit (X11), and maybe even emacs/vim?

I also think the idea should work for as many packages as possible (e.g., terminal, music/movie players; pdf viewers; office apps; latex editor; file managers; apt; etc.).

Does anyone know if anything like this already exists? Or any reason why this idea is doomed?

I could probably code up a simple version of this (e.g., using an sqlite db and python), but if something already exists would prefer to just use that.

Also if anyone knows of a good source of nearly equivalent commands that would also be very helpful.
