Hi Franklin52,

Thanks for your replies. Well your method works but I need to do some more further manipulation. I'm trying to rewrite the solaris password aging script "pwage" for hpux Trusted systems. I already figured out the calculation part I just need to find a way for the script to be able to reply to the user that's why I'm trying to use a for loop.

for j in `find /tcb -name $i -exec ls -1 {} \;`
do
LASTPWCHG=`cat $j | grep u_succhg | sed 's/:/#/g' | cut -d# -f3`
DAYSEC=`echo "60*60*24" | bc`
DAWNOFTIME=`/usr/contrib/bin/perl -e 'print int(time)'`
SECSAGO=`echo "$DAWNOFTIME - $LASTPWCHG" | bc`
echo $DAYSEC
echo $DAWNOFTIME
echo $LASTPWCHG
echo $SECSAGO
DAYSAGO=`echo $SECSAGO/$DAYSEC | bc`
echo $DAYSAGO
done
MAXAGE=90
LEFTDAYS=`echo "$MAXAGE - $DAYSAGO" | bc`
echo $LEFTDAYS
if [ "$LEFTDAYS = 7 ]
then
show a reminder and send to user email address.... etc

done

Maybe a little explaination for benefit of others

DAYSEC= number of seconds in a day = 60*60*24

DAWNOFTIME = total number of seconds from 1970 to the present time

LASTPWCHG = on trusted hpux servers encrypted passwords are stored in directories and has a field called u_succhg with a huge number like example :u_succhg#1300355419: this number is from 1970 to the date where the last password was successfully changed in seconds.

so basically find the time from 1970 minus the time of the last password changed you get the number of days ago password was changed compares that to 90 days password expiry you will get remainder in days when the password going to expire

uudemon(4)						     Kernel Interfaces Manual							uudemon(4)

NAME

       uudemon.admin,  uudemon.cleanu,	uudemon.hour,  uudemon.poll  -	Administrative shell scripts for polling remote systems, cleaning up spool
       directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons

SYNOPSIS

       These shell scripts reside in the following directory:
	  /usr/lib/uucp

DESCRIPTION

       All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the  scripts,  remove
       the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file.

       This  script  reports  status  to  the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the
       results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID  (uucpa)	or
       root.  This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com-
       mand is run with the following parameters: -C7, -D7, X2, -o2, -W1.  This script runs the uusched and uuxqt daemons in the background.  This
       script  polls  the  systems  listed  in	the  /usr/lib/uucp/Poll file.  The uudemon.poll script should be scheduled before the uudemon.hour
       script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script.

FILES

       Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files.  Contains the uucp file.

RELATED INFORMATION

       Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1)

       Files: /usr/lib/uucp delim off
