Launch program from terminal

If it is a GUI application (e.g. .app)

open -a "application name" URL or document name
open -a Safari "https://www.apple.com"

otherwise, it would depend where in the filesystem, the non-GUI application resides, what your PATH environment variable has been set too, and what arguments the command takes from the command-line:

man -t zsh | open -f -a Preview
ruby -e 'puts ARGV.first.capitalize;' "CAT_AND_MOUSE_GAME"
~/Desktop/customprog.py ~/Desktop/input.txt
./located_right_here ./"white-space punctuated input".txt

The tilde (~) character is shorthand for your home directory (e.g. /Users/yourname, etc.). The leading dot means in the current folder location.

How do I launch a program from the "terminal" window?

ex. To open iTunes:

    open -a iTunes

Use quotation marks if the application has a space in its name:

    open -a "App Store"

You can see more examples from the terminal itself, copy and paste:

man open | more
