http://www.commandlinefu.com (and related http://twitter.com/commandlinefu)
In short - it's a repository for unix/bash commands that you want to save for future
use, featuring autocomplete search, voting and commenting (very much inspired
by daily reading: HN, Programming Reddit, Stack Overflow ...). Kept as clean
and simple as possible.
More: I really wrote this for myself as my own collection of command-line
snippets was getting too unwieldy and hard to parse. I just wanted
autocomplete really so I could jump straight to that command I can vaguely
remember in a few characters.
We're quite hot on using Twitter at work for project communication (all SVN
commits tweet) and commandlinefu lends itself nicely to tweet-sized nuggets.
It turns out that it's quite a good way of staying in touch with the latest
commands. All command lists are available as RSS feeds also.
It's still pretty raw at the moment - I've got a few features in the pipeline that
should make it better such as tagging and requesting a needed command (see the
uservoice link). However, it's gone onto reddit today so I
thought now's as good a time as any to ask for HN feedback.
All feedback appreciated via this forum, or uservoice.
A similar site exists for all dot files (configuration files under unix,) which might be helpful: http://www.dotfiles.org
Regarding the actual site, there are a few design comments:
* Yeah, we get that it's supposed to look like a terminal, but the novelty of harsh fonts/colors wears off very quickly. Either having the ability to change it to something else or making a more pleasant default would be nice.
* Make it possible to increase the number of command lines per page. I doubt it is very tolling to generate and submit the pages, but I find it more convenient to just scroll rather than keep clicking 'next.' The way I use your site as of right now, is just keep going through commands, glazing over those I either know or don't find useful until I find the gems. Clicking next continuously is unproductive.
* The "minimize, maximize, close" buttons over the terminal are, as I see now, just a static image to simulate an actual terminal window. This is very unintuitive as I tried clicking them to, what I thought, will make the terminal either span the entire page or load more commands. Either add functionality to buttons or make it obvious that they aren't buttons.
* Finally, it'd be really nice if you don't have to sign up to vote or submit commands. Sometimes I just have one or two commands I'd like to contribute and would not want making an account in YetAnotherWebsite just to do so. You might be missing a lot of useful contributions by making sign-ups mandatory.
Otherwise, well done!
