Hi,

the attached script should give you a start for AIX.

It lists how many days ago your users last logged in.

Please note that the script doesn't list users without a password (they cannot login anyway),
users with a userid less than 12 (those system-related ids should not be touched),
and the userid "nobody" (needed for several system purposes, e.g. lpd).

Have fun!

wmp
awk -F: '$2!="*"&&$3>11&&$1!="nobody" {print $1}' /etc/passwd |\
xargs -I{} lssec -f /etc/security/lastlog -s {} -a time_last_login 2>/dev/null |\
awk -v N=$(date +%s) -F" |=" '
 {if($3!="") {printf "%16s\t%s %.1f %s\n", $1, "last login", (N-$3)/(3600*24), "days ago"}
   else printf "%16s\t%s\n", $1, "never logged in"}' |sort -k2
