'N' lines of Top Command?

Greetings, Gurus!!

I have been searching high and low for this, and have had no luck thus far....is there any way of just returning 'n' number of lines from TOP?

I have a script that calls the TOP command, as well as a couple of other commands, wraps their output to a file, and mails it out. However, lately, the mail hasn't been coming, since the output from TOP has been huge. Is there any way of telling the script to only show the top 'N' number of processes, so that I don't run into this again?

Thanks!

I am assuming that you are using top in the batch mode version, ie top -b -n 1 or something similar. I figure the best way to get N number of lines from this output would be to pipe it through the head command, something like this:

$ top -b -n 1 | head -n 4

This would give you the first four lines of the output of top.

Yep, that was it. I should've seen that. D'oh!!!

Back to the books for me, then.....

Thanks!
