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.

SSH RPC (transparently run command on remote host)

It's useful mostly for your custom scripts, which running on specific host and tired on ssh'ing every time when you need one simple command (i use it for update remote apt repository, when new package have to be downloaded from another host).

Don't forget to set up authorization by keys, for maximum comfort.

Alternatives

There are 4 alternatives - vote for the best!

If you can do better, submit your command here.

What others think

Set up your ~/.ssh/config and you don't need this - just

ssh <host> <command>

Even works with scp, too.

Also, 'hostname' is already a command.

How is this different from running stuff like ssh blah.com ls?

This allow's you to use same command on local and remote host, without code modification or teaching end-users. It more simple than aliases (one symlink do all the work, no need to reload all shells when another command is added), it can be configured in one place and it just works.

I think he means to put in actual host names in place of "hostname". If so it just means you could type

<hostname> <command>

instead of

ssh <hostname> <command>

(assuming you have your .ssh/config set up) and I don't see that as a big enough advantage to outweigh possible conflicts between host names and other commands, and remembering to setup links for all the hosts you use on all your boxes. In terms of teaching end users, a custom system at your site is more of a training hassle than just using the standard commands unless there's a big savings, IMHO.
