figure out how long a job takes to complete

[pry]

I will be doing some volume testing on an AIX computer. I would like to write a script, that will tell me the start and end times of a program. (I really only need the end time, I'll be starting the program, I'll know that time!)I need to write the script as a regular user, I won't have access to crontab. I'm thinking of something like this:

find the pnum of the program
while ps|grep pnum
do
date > lasttime
done


then, the lasttime file will contain the time just before the program ended.. am I figuring this our right? Any help would be appreciated,,

thanks
James

ps - Korn shell is the default

Start the program with a shell, something like...

#!/usr/bin/ksh
. /yourprogramhere
date >> lastime
exit

This will time/date stamp everytime you run the script for testing after your program finishes.

Off to grap another cup...

man time

PHV's example will give you the elapsed time, time charged to user and time charged to sytem in seconds in the format:
real 10.5
user 0.3
sys 3.5

If you want to be thorough in your testing try:

#!usr/bin/ksh
date >> lasttime.log
/usr/bin/time /yourprogramhere 2>> lasttime.log
date >> lasttime.log

This will give you the start time, system times from the time command, and end time for your program.
