How to Digging Up Movie Info from IMDb using script

A more sophisticated use of Internet access through lynx and a shell script is demonstrated in this hack, which searches the Internet Movie Database website (http://www.imdb.com/) to find films that match a specified pattern. What makes this script interesting is that it must be able to handle two different formats of return information: If the search pattern matches more than one movie, moviedata returns a list of possible titles, but if there's exactly one movie match, the information about that specific film is returned.

As a result, the script must cache the return information and then search through it once to see if it provides a list of matches and then a second time if it proves to be a summary of the film in question.

The Code
#!/bin/sh

# moviedata - Given a movie title, returns a list of matches, if
# there's more than one, or a synopsis of the movie if there's
# just one. Uses the Internet Movie Database (imdb.com).
