What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/

Universal configuration monitoring and system of record for IT.

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)

Terminal - SSH RPC (transparently run command on remote host)

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.


There are 12 alternatives - vote for the best!

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?

Comment by symgryph 169 weeks and 1 day ago

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.
