expect-lite is an quick and
easy command line automation tool.
Written in expect, it is designed to
directly map an interactive terminal session into an automation script.
expect-lite scripts use special character(s) at the beginning of each
line to indicate the action. Basic expect-lite scripts can be created
by simply cutting and pasting text from a terminal window into a
script, and adding '>' '<' characters. No knowledge of
expect is required!
The main purpose is keep it simple.
However, the advanced features allow pretty creative scripting.
