rsteff at Enu-1:~$ top -n 1 -b > top.out

top.out starts out with:

... and more, up to 232 lines.

I notice that running top with a limit to one iteration doesn't show 
what I usually see, which shows thunderbird, firefox, virtualbox, and 
the other programs I'm running in the top 10 lines more often. What's 
the best way to get the useful information you're asking for?
