Have you tried out last command? It will show listing of last logged in users in system. Using last and entries from /etc/passwd you should able to come with something.

Use the following command to get list of regular users:
Code:
export UGIDLIMIT=500
awk -v LIMIT=$UGIDLIMIT -F: '($3>=LIMIT) && ($3!=65534) { print $1}' /etc/passwd
Code:
#!/bin/bash
export UGIDLIMIT=500
ALLUSER=$(awk -v LIMIT=$UGIDLIMIT -F: '($3>=LIMIT) && ($3!=65534) { print $1}' /etc/passwd)
for u in $ALLUSER
do
lastlog -u $u | grep 'Never'
done
