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.
