As i was trying to use your -b option, i realized there was a:
-f filename
option on Unix, which printed out the output of top to filename, in a readable format.
Thanks you all for your help

Another way is to call top in batch mode (-b). This tells top to not send any
fancy control characters. If you want to catch just one iteration though,
you should also pass it "-n1" so that it doesn't just scroll screenfulls of
top information on your terminal.
Attached is a little quickie program I wrote to watch various aspects of top's
output over time. It might help to show how one could process top data.
