I use one of the contrib bashpodder shells, this one can handle bittorrent, has first only (download only the last podcast on a rss feed), and catch up.
bashpodder.shell
Code:
#!/bin/bash

Usage: $0 [OPTIONS]
Options are:
-v, --verbose display verbose messages. Also enables wget's continue
option.
--catchup_all write all urls to the log file without downloading the
actual podcasts. This is useful if you want to subscribe
to some podcasts but don't want to download all the back
issues. You can edit the podcast.log file afterwards to
delete any url you still wish to download next time
bashpodder is run.
--first_only grab only the first new enclosed file found in each feed.
The --catchup_all flag won't work with this option. If
you want to download the first file and also permanently
ignore the other files, run bashpodder with this option,
and then run it again with --catchup_all.
-bt --bittorrent launch bittorrent for any .torrent files downloaded.
Bittorrent must be installed for this to work. The
the script and bittorrent process will continue running
in the foreground indefinitely. You can use ctr-c to
kill it when you want to stop participating in the
torrent.
--sync_disks run the "sync" command twice when finished. This helps
makes sure all data is written to disk. Recommended if
data is being written directly to a portable player or
other removable media.
-u, --url_list ignore bp.conf, instead use url(s) provided on the
command line. The urls should point to rss feeds.
If used, this needs to be the last option on the
command line. This can be used to quickly download just
a favorite podcast, or to take a few new podcasts for a
trial spin.
-h, --help display this help message
