How to make a python script become a unix command?

Question

How do I make a python script a unix-able command?

Let's say i have a python script:

print "hello foo bar"

and i want to call the python script like a normal linux command, something that people can:

deb www.myfoobar.com foobar
deb-src www.myfoobar.com foobar
sudo apt-get install foobar

Then after installation, something that someone can just call from terminal:

$ foobar
hello foo bar

Answer 1

Put following shebang line at the top of the script.

#!/usr/bin/env python

Make a script executable using following command:

chmod +x foobar

Move the script to somewhere in the $PATH (for example: /usr/local/bin)

mv foobar /usr/local/bin
