Script do compare and delete

Vogra — Fri, 01 Jun 2001 14:22:36 GMT

Hi All!
How can I solve the problem below:
I need to clean de passwd file from old users. I have a $list that have users not able to access the system. I have to make a script that read a line (first n characters) from passwd file, compare this with this list and, if it's match, delete the line from passwd file.

I'd suggest feeding your list to the userdel command and letting it do the work for you.

while read i
do
userdel -r $i
done < list

Hi,

Before you run this script, I would surround the userdel command with something like:
if [ "${i}" != "root" ]
then
userdel -r ${i}
fi

AND
1) Make sure that you are logged in as root in at least two sessions
2) you have a copy of the passwd file
This way you can get yourself out of possible trouble as fast as you got yourself into trouble.

Regards, Clay
