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.

Use sed to remove comments from a file.

In this example the comments begin with #.

The command '/^#/d' remove line starting with #.

The command 's/#.*$//' remove comments at end of lines.

sed -re '/^#/d ; s/#.*$//'
