If you use Mail.app to read RSS feeds and want to export the URLs for those feeds (maybe you want to use some other RSS reader now?), you can use this command.

perl -ne 'print "$1\n" if m#(.*://[^<]+)#' \ 
~/Library/Mail/RSS/*/Info.plist

Type the above at a shell prompt. If the previous sentence sounds like gibberish, here’s the step by step:

1. Go to the Utilities folder (inside Applications)
2. Open Terminal
3. Type the command above at the prompt (note that the backslash is there so the shell doesn’t get confused about the fact that this command takes up two lines – the alternative is to just type the whole thing on one line and get rid of the backslash)

NetNewsWire

If you’re specifically trying to get your RSS feeds from Mail.app and into NetNewsWire, you can use this script I created: mail2nnw.pl

1. Download the script from here (it’s zipped): mail2nnw.pl.zip
2. Once it’s unzipped, double-click on the mail2nnw.pl icon
3. When it says it’s finished, you’ll find a file called Feeds.opml in your Home directory, suitable for importing into NetNewsWire.
4. Open NetNewsWire, choose “Import Subscriptions…” and finish by updating all of the subscriptions using SHIFT+COMMAND+R (or go use the menu item instead). All of the icons and titles will automatically be updated after the update.
