Awk help
Posting this for a friend:
I'm having a tough time coming up with an awk command for the following question:
Using the /etc/passwd file, what command will create a list of all usernames and user id numbers of all users who have accounts on the system, sorted by user id number?
The format of the passwd file is as follows:
usrid879:x:1382:1000:Student - John Q Public - 06M8W1_ZF_423_M40,,,:/home/usrid879:/usr/bin/ksh
I need to create a listing that looks like this:
John Q Public usrid879
The only problem I'm having is switching between the ':' and 'space' delimiters. Any help would be much appreciated.

unshadow
UNSHADOW(8) System Manager's Manual UNSHADOW(8)
NAME
unshadow - combines passwd and shadow files
SYNOPSIS
unshadow password-file shadow-file
DESCRIPTION
This manual page documents briefly the unshadow command, which is part of the john package. This manual page was written for the Debian
GNU/Linux distribution because the original program does not have a manual page. john, better known as John the Ripper, is a tool to find
weak passwords of users in a server.
The unshadow tool combines the passwd and shadow files so John can use them. You might need this since if you only used your shadow file,
the GECOS information wouldn't be used by the "single crack" mode, and also you wouldn't be able to use the '-shells' option. On a normal
system you'll need to run unshadow as root to be able to read the shadow file.
SEE ALSO
john(8), mailer(8), unafs(8), unique(8).
The programs are documented fully by John's documentation, which should be available in /usr/share/doc/john or other location, depending on
your system.
AUTHOR
This manual page was written by Jordi Mallach <jordi@debian.org>, for the Debian GNU/Linux system (but may be used by others).
John the Ripper and mailer were written by Solar Designer <solar@openwall.com>. The complete list of contributors can be found in the CRED-
ITS file in the documentation directory.
