I have been playing around with FISH for a few days and I just tried to switch it to my main shell. That worked fine but now none of my software from MacPorts is recognized.
The python script made this entry from my .profile to my config.fish file
set_default export PATH "/opt/local/bin:/opt/local/sbin:$PATH"
but I get this error
fish: Unknown command 'set_default'
/Users/ley/.config/fish/config.fish (line 1): set_default export PATH "/opt/local/bin:/opt/local/sbin:$PATH" ^ in . (source) call of file '/Users/ley/.config/fish/config.fish', called on standard input,
I fiddled with the set command a bit but that didn't seem to help much.
