Need to sort/change modify 2300 users ...

Ok, so here's my project I've been given and I know very little about this.

I have an AIX unix box that has over 2300 local users.

Any user with 4 or less characters in the username does not get changed.

Any user with 5 or more needs to have the attribute shell=/bin/ksh changed to shell=/bin/true

I have a vague idea how to do this, but everyone on these forums seems pretty helpful and nice, so I thought i'd give it a shot and see what you guys would recommend doing.

Thanks a ton guys!

ruptime(1)						      General Commands Manual							ruptime(1)

NAME
ruptime - Displays the status of each host on a network SYNOPSIS
ruptime [-ar] [-l | -t | -u] ruptime [-ar] [-l | -t | -u] [machinename] The ruptime command displays the status of each host on a local network that is running the rwhod daemon. If machinename is specified, only the status of that machine is displayed. OPTIONS
Includes all users. Without this option, users whose sessions are idle an hour or more are not included. Sorts the list by the load aver- age over 5-, 10-, and 15-minute intervals prior to a server's transmission. The load averages are multiplied by 10 to represent the value in decimal format. Reverses the sort order. Sorts the list by the length of uptime. Sorts the list by the number of users. DESCRIPTION
The status lines are sorted by hostname unless the -l, -t, or -u option is indicated. The status information is provided in packets broad- cast once every 3 minutes by each network host running rwhod. Any activity (such as the power to a host being turned on or off) that takes place between broadcasts is not reflected until the next broadcast. Hosts for which no status information is received for 11 minutes are reported as down. EXAMPLES
To get a status report on the hosts on the local network, enter: $ ruptime Information similar to the following is displayed: host1 up 5:15, 4 users, load 0.09, 0.04, 0.04 host2 up 7:45, 3 users, load 0.08, 0.07, 0.04 host3 up 2:28, 0 users, load 0.01, 0.02, 0.03 host4 up 3+01:44, 1 user, load 0.01, 0.02, 0.03 host7 up 7:43, 1 user, load 0.06, 0.12, 0.11 (Output may be formatted differently on your system.) To get a status report sorted by load average, enter: $ ruptime -l Information similar to the following is displayed: host2 up 7:45, 3 users, load 0.08, 0.07, 0.04 host1 up 5:18, 4 users, load 0.07, 0.07, 0.04 host7 up 7:43, 1 user, load 0.06, 0.12, 0.11 host3 up 2:28, 0 users, load 0.01, 0.02, 0.03 host4 up 3+01:44, 1 user, load 0.01, 0.02, 0.03 (Output may be formatted differently on your system.) FILES
Indicates data files received from remote rwhod daemons. SEE ALSO
Commands: rwho(1), rwhod(8) ruptime(1)
