Idris,

(Sorry for the crumminess in replying, I've been a bit busy lately!)

The problem's a bit more complicated than you think, but not *that*
complicated.

The username and password need sending via a HTTP POST request, so you
could use 'lynx' to send the form data via it's -post_data option.

The login page I guess you're think of, however, has a unique number in
it every time it's issued to nobble people trying to do what you're
trying to do.

You'd need to:

1) Grab a fresh copy of the login page.
2) Search the page for the unique ID, which is somewhere as a hidden
form field, eg: <input type="hidden" name="whatever" value="123456789">
and store the value in a variable
3) Send the values to the script via a POST request through lynx.
Something like:
echo -e "username=foo\npassword=bar\nuniqueid=$id\n---\n" | lynx -dump
http://server/script

IIRC there's also a cookie involved.

James
