expect will help you here.

OTOH writing this in a language like perl would be a
major win since it supports lots of nice WWW/HTTP
modules.

Or, you could get URLs using something like "lynx".

It would be more helpful to say what it is you want
to do in terms of the problem you're trying to
solve.

You could do it with an Expect script, but it would be easier to do
with wget (www.gnu.org) as it's designed for non-interactive fetching
of things off of web servers.

  The opinions expressed above are just that...

"wget" is probably a better choice for getting URLs--it's lighter
weight for one. It should be available at a GNU mirror.

Opinions expressed herein are my own and may not represent those of my employer.

The best way is abandoning the SHELL interpreter,

I had wroten such a program using PERL+PERL MODULE

very easy,the module is powerful.

you can find the on CPAN.

telnet somehost.com 80 < command-file > output

command-file is the name of the file which commands to telnet are put
in.  it would read as follows

GET /path/to/file.html

and output would be the output from the webserver.

Very simple.

Telnet is an interactive appliacation, so I do not belive that you can
redirect anything to it. But if you use "expect" telnet will think that you
are typing at the keyboard.

Ex:

#!/usr/local/bin/expect -f
spawn telnet HOSTNAME 80
send "GET index.phtml\r"
expect eof
