Subject: limit number of process in top with non-interactive mode


Top command in Linux is allowing to control the number of processes only
in 
the 
interactive mode. I want to control the number of processes in 
non-interactive batch 
mode. Is there any other version of top available ? Or is there a way to
do 
so with 
the current version itself? 

Note: Manual page for top is inappropriate with the command. 
For example, "top 10" reports an improper use of command though it is
valid 
according to the man page. 
 [Actually this is asked by one of my colleague, asking here as I am out
of 
answer]

Nikhil

If you are looking to do it non-interactively, just add a couple more
lines to your batch job to get the desired outcome.  I am not the best
scripter, but something like:

Top -b -n 1 > /tmp/top.txt
Head -n 22 /tmp/top.txt > /tmp/top2.txt

This gives me all the top header info and the first 10 processes.  I
know it's not pretty, but you get the idea.
