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.

Execute a sudo command remotely, without displaying the password

The ssh command alone will execute the sudo command remotely, but the password will be visible in the terminal as you type it. The two stty commands disable the terminal from echoing the password back to you, which makes the remote sudo act as it does locally.

Alternatives

There are 5 alternatives - vote for the best!

Know a better way?

If you can do better, submit your command here.

What others think

An easier way to do this is with the -t flag to OpenSSH, forcing it to allocate a tty even though you're not starting an interactive shell. This allows the remote program to do effectively the same thing that stty is doing. Also makes it handy if you want to do something like ssh -t server 'some-interactive-program'.

Cool, I wasn't aware of that. Thanks for the tip.

Also, is there any reason why you wouldn't want to use -t? Any unexpected side effects?
