Creating a .command file

Open a text editor like TextEdit and type in your commands:

cd /path_name/folder_name

run python command

Save the file as my_command_name.command where the extent really is ".command" rather than the default of ".txt".

Are you expecting a reply? You have given me nothing with which to help.

As I mentioned, the .command file is a script, and to run it, you must make it executable.

Rock.command contents:

#!/bin/bash

# assumption that runserver.py is in the Rock folder

cd ~/Desktop/Rock

python runserver.py

A .command file must be made executable before it is run. You do this in the Terminal, and in this instance, you are making it executable strictly for you:

chmod +x my.command

Now, providing the contents have been tested interactively beforehand in the Terminal, you can double-click this my.command file in the Finder, and it will pop a Terminal window, run, and then kill the Terminal session without quiting the Terminal window it created.

For your example, you need to make your my.command file a Bash script which will honor your change directory (cd) command in a Bash shell, before running the Python script:

#!/bin/bash

# change directory to /Users/myname/Test

cd ~/Test

# run the Python script located in your home directory

./my.py

If you just wanted to run a Python script in your my.command file, you could replace the Bash invocation line with:

#!/usr/bin/python

# coding: utf-8
