Exploring Expect

Exercises

1. Write an ftp mirror script—which copies a file hierarchy from one anonymous ftp site to another. Do it using a single spawn id. Do it again, but use two spawned ftp processes—one to retrieve the listings and one to do the I/O. What are the advantages and disadvantages of these two approaches.

2. Extend one of the scripts from the previous exercise to update multiple ftp sites simultaneously.

3. Write a script that watches a user interacting with a process and produces a new Expect script that automates the session.
