Time taken by process after it's completed

[spookie]

Hi,

Is there any way to know how much time a process, with say PID 123, has taken to complete after it gets completed. i.e.ps -ef does not show up the process.

Perhaps truss could help here?

I want to be good, is that not enough?

Thanks for the response KenCunningham, but i have never used truss.Can you shed some light on how to use it. Also i don't have proc filesystem mounted on my server. Will i be able to use truss then.

If you invoke it with "time", then it gives all that info.

If you want it after the fact, you might have to turn accounting on.

Another vote for the "[tt]time[/tt]" command here. You need to add it to the front of the command, but it will give a report of elapsed, system CPU, and process CPU time used. See the man page. Extremely easy to use.
