Very Computer

Problem: one desires to let the machine to (1) perform unattended
search on certain topic using 'jughead' or 'veronica' while
nohup; (2) download search results to shell account or email to
an address; (3) perform same topic search at a later date, but
bypass information that has been accessed before (what search
tool, not known, to me?)

Inquiry: (1) is there any existing programs or tools that have the
above capability; (2) if not, could shell programming, be it Bourne
shell, csh, or ksh, resolve the above problem?  Somehow, I think
if something like 'sendkey' could punch a key for you could help,
yet, I don't know.  I man-paged 'setkey' and 'stty', they did not
seemed to help.

Thanks in advance.
