Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Creates PodFeeds.txt, a file that lists the URLs of rhythmbox podcasts from the rhythmdb.xml file.

The first grep any line with pod-feed in it plus the following five lines.

The second grep throws out any line not containing .

sed removes the leading four spaces then and the trailing .

Using a colon as sed's separating character avoids having to escape the /.

Works ok with Mythbuntu 9.04 (used mostly as a three line bash script).

What others think

In the description elements in angle brackets have not appeared.

I'll try now with quotes.

line 3 ends 'not containing ""'

line 4 ends 'the trailing ""'

Best regards dogflap.

Well that attempt to get angle brackets into the description did not work. Third try.

Line 3 ends in "location" enclosed in angle brackets.

Line 4 should end in "/location" enclosed in angle brackets.

best regards dogflap
