Since the Raspberry Pi was released, the python programming got a new life.

So, many customers ask to me how to do some simple task using this programming/scripting language.

Checking for root is useful if you want to check whether a user has the privilege to bind a socket to a port less than 1024. In this case, you can generate a useful error message beforehand, rather than just trying and having the bind command fail.




In python is a really simple task,

just add the following few lines to your program:

import os, sys

# if not root...kick out

if not os.geteuid()==0:

    sys.exit("\nOnly root can run this script\n")


Please, take care of the following notes.

If you don't want a user can execute your script you shall issue the following bash command on your script:

$ chown root

$ chmod 700
