Well it can be anything . .
I have written three scripts by now and after successful execution of each script, there's a message as shown before.
Only the field values are changing . .
Like,
5.85u 4.679s 0:16.78 105.2% 1+6k 7+8io 5pf+7w
I want to know the significance of each field . .
Thanks for reply

It's telling you how much time something spent running as User(5.85 seconds), as System (4.679 seconds), and a total of 16.78 seconds (so must have spent some seconds just sitting waiting for I/O).
Try time sleep 10 in your shell.
The rest I'm not sure of. I'm not even sure what the "something" was since you refuse to post your script. What's your system? uname -a if you don't know.
