The fish-shell was new to me, so I read the documentation – something I really recommend. Look for the title “Initialisation Files“: http://fishshell.com/docs/current/index.html#initialization
So it looked like you call your python scripts from ~/.config/fish/config.fish
So I installed fish on my Macbook and I had to create the config.fish file. In that I just placed:
~/gash.py
That executes the python program gash.py in my home directory. Of course the #! line has to be correct and I have to have execute permissions (as usual). I entered the fish shell and it executed the program.
Thanks for that, the fish-shell looks quite interesting. I love stackoverflow.
