Google may actually give you a short-term IP ban (a day or so), so spamming their servers with spurious connections may not be in your best interest -- doubly so if you're at a workplace.

I've got something like this in my .bashrc so I can access commandlinefu from within the shell: cmdfu(){ wget -qO - "http://www.commandlinefu.com/commands/matching/$@/$(echo -n "$@" | openssl base64)/plaintext"; } It's like man but for one-liners.

This probably matters a lot less than younger people think. If you grew up touch-typing you got used to being able to put data in as fast (or almost as fast) as you could think it. If the input rate is slowed down, you feel like you're going to lose thoughts before they get captured. Folks who did not grow up touch typing, though, simply learned to construct a longer-lasting mental model, which they can then write ou…

Having a slow typing speed still means that one spends a lot of time typing, rather than doing other things, even if one can still accomplish the same mental processes without having to record it "live".

I like to use something like this in such situation: $ curl -s -D /dev/stderr news.ycombinator…

You can also use the -i option which prints out the headers and the response body (which is perhaps a bit too noisy). curl -i http://news.ycombinator.com

Interesting. Can you explain how the command works? I did look at the commandlinefu API page but didn't get it. I know UNIX and also specifically what "$@" means in UNIX but didn't get the meaning of the two uses of it in the commandlinefu URL you show, nor what the openssl part does.

    [URL]/matching/ssh/c3No - Search results for the query
    'ssh' (note that the final segment is a base64-encoding
    of the search query)

     $ echo -n ssh | openssl base64
     c3No
