Fantastic, you're a star :)

One last point how can I print all the associated deatils attached to
that uid i.e username, home dir etc and then cycle through for every
uid and print the same information for each respective uid? The uid's
need to be in order i.e something like

uid: 0, username: root etc...
uid 50, username: mysql etc...


Many many thanks
