Automation With Expect, an Open Source Software Utility

“I recently came acrossexpect (the expect package in Debian and
Ubuntu): a powerful utility that can script interactive
operations.

“If you’re not familiar with TCL syntax, you can get autoexpect
from Wi-Fizzle.com. This spawns a shell, and then records
everything you do in that shell. Hit Ctrl-C when you’re done, and
then either run the generated expect script as-is, or edit it to
tidy it up a bit. In particular, autoexpect records keystrokes one
by one, whereas you can put them all in at once. It records the
full prompt, where the $ at the end may suffice.”
