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.

Nice trick. It is a suprise that this works even if there are symlinks that point to other symlinks, because the man page of find doesn't explicitly document whether it follows the link once or until it gets to a non-symlink file.

I tested that find indeed follows links recursively, so symlinks to symlinks won't get reported as broken links. It even detects and complains about loops.

The man pages call these orphan or orphaned links. Adding those terms so I can find it next time instead of developing it independently again. ;-)
