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,…):

This will make your bash scripts better!!
process-getopt is a wrapper around getopt(1) for bash that lets you define command line options (eg -h, --help) and descriptions through a single function call. These definitions are then used in runtime processing of command line options as well as in generating help and man pages. It also saves a little time in coding and in producing nicely formatted documentation. It is quite similar to GNU's argp in glibc for compiled languages and OptionParse for python.
