`open` is one I use all the time. I love that simple command.

    alias tab='open . -a iterm'
    alias phpstorm='open -a "PhpStorm"'
    alias smerge='open -a "Sublime Merge"'

etc. I use those more than I do the Open/Recents dialogs in the respective apps.

I made a script to open files with rofi

Looks like this:

In a vscode terminal I just use the alias "o" and it opens that at the correct location, then I can navigate and pick a file to open in the editor.
