Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

As part of my normal workflow I ssh into another user's machine, switch user to them, run a command, then exit out to my own machine again:

ssh hostname
sudo su user
runcommand
exit
exit

Is there a way to cut this down to a single line command? e.g.

ssh --someflags "runcommand"

I have tried this but get prompted for the other user's password which I do not have:

sudo ssh user@hostnme "runcommand"

Something like ssh myaccount@somehost "su -u <user> -c <command>" wouldn't work? –  Fiisch Oct 4 '13 at 18:56
    
You could always publish your key into their authorized_keys file. Then you can connect to using that users account directly. –  Zoredache Oct 4 '13 at 19:28

Do you have a user on all of the remote computers? I guess this should work, but im not sure i understand your setup correctly.

ssh youruser@hostname "sudo -u remoteuser runcommand"

And how exactly does this address the Esker's problem? –  Fiisch Oct 4 '13 at 18:59
    
Yeah, I misread. Updated the answer. –  piksel bitworks Oct 4 '13 at 19:00

With a bit of tweaking, that worked, thanks. ssh -t hostname "sudo su user -c runcommand" –  Esker Oct 4 '13 at 19:03
