would "top -b" help?  From the top manpage:

b    Batch mode. Useful for sending  output  from  top  to
other  programs or to a file.  In this mode, top will
not accept command line input. It runs until it  pro­
duces  the  number of iterations requested with the n
option or until killed. Output is plain text suitable
for display on a dumb terminal.
