Hi:

Expect is a tool for automating interactive applications. While it's available on most Linux systems, you typically have to download it for other systems. Here's the expect home page:

http://expect.nist.gov

The most common example is automating the passwd command which is impossible from the shell:

#!/usr/local/bin/expect --
# wrapper to make passwd(1) be non-interactive
# username is passed as 1st arg, passwd as 2nd
# Executable only by root
set password [lindex $argv 1]
spawn /usr/bin/passwd [lindex $argv 0]
expect "password:"
send "$password\r"
expect "password:"
send "$password\r"
expect eof
# end script

An excellent book is Exploring Expect by Don Libes.

Thanks Nails!!
