Internet Spy (i-spy)
I-Spy is a Perl script which identifies new files on various remote FTP and Web sites. It grabs and compares contents of FTP directories and web pages. It will then compile a report and either send it via e-mail or save it as a web page. You may also request both deliveries of the report. For e-mail reports, you may request plain text or HTML. I-Spy logs its activity as it chugs along. You may specify the log directory, or I-Spy will try to find one automatically. For web page reports, I-Spy will attempt to store the log in such a place where it may be referenced by the report and served by the web server.
