How to use Octave app on macOS Mojave
Solution 1:
You can use the following to open Octave with a file:
open -a "Octave" /path/to/file
If you want, alias this to octave by adding this line to your ~/.bash_profile:
alias octave="open -a \"Octave\""
Now you should be able to use octave /path/to/file anywhere.
