So, I need a script to run grep on the output appearing on the console.
Any thoughts??
Thanks,

Why telnet and not ssh? ssh is far easier to automate. You could just do
ssh username@host command | grep ... and it'd do what you expect.
without ssh, you might have to bodge a monster with
expect.

ssh-argv0
SSH-ARGV0(1) BSD General Commands Manual SSH-ARGV0(1)
NAME
ssh-argv0 -- replaces the old ssh command-name as hostname handling
SYNOPSIS
hostname | user@hostname [-l login_name] [command]
hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name]
[-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command]
DESCRIPTION
ssh-argv0 replaces the old ssh command-name as hostname handling. If you link to this script with a hostname then executing the link is
equivalent to having executed ssh with that hostname as an argument. All other arguments are passed to ssh and will be processed normally.

See ssh(1).
FILES
See ssh(1).
