Dear Sir/Madam

We have an on-going program to run "top" command at certain time and
generates the report below. We need to extract the 4 lines above the
heading "PID USERNAME LWP......" to another file. Could we use "tail"
command to do that ? If yes, what option should we use. If you have
better suggestion, please let me know also.

Thanks, Bill

You use tail to get the last n lines of a file, or everything from the
n'th line to the end. You use head to get lines at the beginning of the
file. For lines in the middle you can pipe head and tail together, or
use a more versatile tool such as sed, awk or perl.

IF this is a Solaris question I suggest using prstat over top unless
there is something
specific that top does that prstat does not...
