You nailed it, thanks for the hint lembas.
In the CLI, I do this:
tmptube https://www.youtube.com/watchwhatever
Now I tried using ./ before (and .sh at the end, though I've tried this by
itself with no success).
According to this, I'd need to make launchy understand it better. For now, my
path to EXE is /home/user/tmptube.sh
When I try this ($ /path/to/shell/script/tmptube.sh) in the CLI, it fails.
According to this
(http://www.cyberciti.biz/faq/howto-run-a-script-in-linux/), I need to create
a bin folder and put that script in. Maybe then it will work.
