Question

I’m attempting to code a script that outputs each user and their group on their own line like so:

user1 group1   user2 group1   user3 group2   ...   user10 group6 

etc.

I’m writing up a script in python for this but was wondering how SO might do this.

p.s. Take a whack at it in any language but I’d prefer python.

EDIT: I’m working on Linux. Ubuntu 8.10 or CentOS =)

For *nix, you have the pwd and grp modules. You iterate through pwd.getpwall() to get all users. You look up their group names with grp.getgrgid(gid).

import pwd, grp for p in pwd.getpwall():     print p[0], grp.getgrgid(p[3])[0]
