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.
Use your favourite RSS aggregator to stay in touch with the latest commands. There are feeds mirroring the 3 Twitter streams as well as for virtually every other subset (users, tags, functions,…):

You can implement a FOR loop to act on one or more files returned from the IN clause. We originally found this in order to GPG decrypt a file using wildcards (where you don't know exactly the entire file name, i.e.: Test_File_??????.txt, where ?????? = the current time in HHMMSS format). Since we won't know the time the file was generated, we need to use wildcards. And as a result of GPG not handling wildcards, this is the perfect solution. Thought I would share this revelation. :-)
There are 2 alternatives - vote for the best!
