telnet script?

[koeicjm]

how can I write a script for login a remote server using telnet , and to do sth at there.

There is a utility called "expect" which you can use to do this. Alternatively there is a telnet module for Perl which does the same job.

What is 'sth'? If it is a particular command you'd like to run you might consider using rcmd instead. Mike

I try to install expect from freebsd 's pkg, but when I try to use it,wright a script :
#! /bin/sh
spawn telnet 192.168.1.16
expect "User:"
send <jchen\r>
expect &quot;Password:&quot;
send <winner\r>
interact

Is it right, I got error &quot;spawn: not found&quot;
but I really didnot know where can I find it ,
and what is it? What should I do ?
I only want use the script to login remote server,
using tar to expand a tar file and login root
to exceute a shell.
