Say, I have a python script named hello.py, which I run on mac as: 

$ python hello.py

What do I need to do to run it as: 

$ hello

    You need to create alias for the above command in bash_aliases file. – Avinash Raj Sep 18 '15 at 16:28

Add a "shebang" to the top of the file to tell it how to run your script.

#!/usr/bin/env python

Then you need to mark the script as "executable":

chmod +x hello.py

Then you can just run it as ./hello.py instead of python hello.py.

To run it as just hello, you can rename the file from hello.py to hello and then copy it into a folder in your $PATH.

  1. add the following line at the beginning of the script:

#!/usr/bin/env python

  1. rename hello.py to hello

  2. change the script to be executable: chmod 755 hello
