This is a multi-part message in MIME format. --------------3I5dazuS4QtlY0107pPjQxYY Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 7bit I've got some scripts which are intended to run on a new EC2 instance right after it is created. Since the script needs to install packages it need to run as root. But because I don't have sudo installed at this point (it is a brand new instance), I've only got 'su' to get root. The script itself is launched over SSH with the ec2-user account and there is no root password at this point in the startup. My first attempt was to put this inside the script itself: if ["$($whoami)" !="root" ];thenexec su -c"$0" exit1 fi But su complains that I'm not allowed to execute a command using the -c option as root. How else can I get this script running as root remotely in a completely unattended way? Cheers Ari Maniatis --------------3I5dazuS4QtlY0107pPjQxYY--
