running interactive program from shell script

[Jay Moore]

I need a shell script that initiates a telnet session to another host. I have 
come up with the following, but unfortunately it terminates when the script 
is finished. What I wanted was for the telnet session to remain "alive" and 
interactive until manually terminated.

Is there a way to accomplish this in a shell script? 

I've been told that I'll have to use "expect" or similar to accomplish this, 
but it seems to me that I should be able to do this using just Bourne shell 
commands. 

#! /bin/sh

    (sleep 3;
    echo "password";
    sleep 3;
    echo "ls -la";
    sleep 3;
    ) | telnet -l user 192.168.0.2

Thanks,
Jay
