Exploring Expect

Written by the author of Expect, this is the first book to explain how this part of the UNIX toolbox can be used to automate Telnet, FTP, passwd, rlogin, and hundreds of other interactive applications. Based on Tcl (Tool Command Language), Expect lets you automate interactive applications that have previously been extremely difficult to handle with any scripting language. The book briefly describes Tcl and how Expect relates to it. It then describes the Expect language, using a combination of reference material and specific, useful examples of its features. It shows how to use Expect in background, in multiple processes, and with standard languages and tools like C, C++, and Tk, the X-based extension to Tcl. The strength in the book is in its scripts, conveniently listed in a separate index.
