Execute a sudo command remotely, without displaying the password

stty -echo; ssh -t HOSTNAME "sudo some_command"; stty echo
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.

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?
