Small question:

In the readme (first section) you use, as an example, the command:

"Run adduser bob 2>/dev/null"

why do you add the "2>/dev/null" part? I see a lot of tutorial/guide/example/etc... do that! I understand what it does (send the stderr to devnull) but i don't understand why would i want to do that?

Adduser will fail a second time, and show "user already exists" or similar. We hide that via the redirect
