process shown on top does not show on ps

[Henry Chua]

Hi,

I got this query about using ps. It seems that a pid I found on top( a java process) cannot be found in ps. Is this possible. I see similar posting in the past but don't really understand the resolution. Can you please help?

Regards
Henry

Yeah, cometimes it happens that when a process runs you applied command top and its life time may be 3-4 secs. Or it may be run a while and while you run ps just after top it may be finished its process or operation. So better if you wanna keep track of processes you may write a shell script to track all processes.
