Create a shell script named, say, ModUsers with this:
[tt]
#! /usr/bin/ksh
for USER in $*
do
chuser attribute=new_value $USER
done
[tt]
Try [tt]man chuser[/tt] to get a list of user attributes and their possible values.
Use the script like this:
[tt]
ModUsers user1 user2 user3
[tt]
I hope it works...
