Expect is really cool, and you can use autoexpect to MAKE an expect script from a session, like a macro recorder!

Here is my script to just telnet to port 25 to see the Sendmail version:
set timeout 10
spawn telnet $argv 25
match_max 100000
expect -exact “sendmailâ€
send — “quitrâ€
expect eof
It was made with autoexpect and then edited, there is some more stuff in the file autoexpect spit out.
