Each submitted Linux command – to be honest there are a few command submissions for other operating systems but the majority is pure Linux – lists the command itself and a description provided by the author of the command. There will also be information about the author, the date the Linux command has been submitted and the amount of votes that it received.

Logged in users can vote, leave comments or report a command as malicious. Command-Line Fu can be accessed with an Open ID.

The site features a search engine and will also post new commands submitted to the site to a Twitter account. The site would do good to provide a list of all available commands to print it or save it in a text document format. It is still a very interesting resource for Linux users who work with the Linux command line regularly.
