mpodder

If you're looking for a simple and efficient podcast receiving tool, mpodder is a great choice. This command line-based podcatching software is written in Perl, so it can be installed and run easily on various operating systems like Linux and the BSD's.

mpodder is designed to be called from cron, and it notifies you of new content via email or a kdialog/xmessage popup. You can also customize the software to download only feed items from the last n days and bring feeds up to date without downloading all old items using the "catchup" command.

To list current feeds, use the "list" operation, which can be filtered using Perl-style regular expressions. Adding feeds is as simple as using the "add" operation followed by the URL of the feed, while removing them involves using the "remove" parameter and a filter.

Fetching new feeds is the default operation of mpodder, but you can specify a filter to download only feeds whose URL matches it. Similarly, if you've just added a new feed but don't want to download all the items in it, use the "catchup" operation instead.

For those who want to see what mpodder is doing more explicitly, you can use the "--pretend" option to simulate most operations. Additionally, using the "--verbose" and "--debug=n" options can make mpodder print out more information than usual about what it's doing. Overall, mpodder is a reliable and customizable tool for all your podcatching needs.
