>JRF: One simplistic way to find the users who haven't logged in is to use "last name"

Yes but very slow and it will have to read the file for each user.

Hi (again):

Yes, of course. That's why i used the word "simplistic". For performance, I'd probably use a Perl hash (associative array) to hold the account names seen by running 'last()' once. Then, walk '/etc/passwd' testing each account name for its presence in the hash. Existence in the hash means that the account has had activity, so skip reporting it. The absence of an account in the hash signifies a user without activity and that's a name to list.

it is good idea to use in Perl arrays, OR more easier in not busy hour of system they can be collected with a cronjob ,preferably after midnight like ;

# last > /tmp/last.file ## This run inside cron
# cat /tmp/last.file |awk '{print $1,$3,$4,$5}'| grep -E 'User_We_Look_For|Jun 23'

just an idea derived from JRF 's idea..
