Run command as not-root

Run command as not-root

Hi everyone

At work, I have to run a command in an AWS instance. In that particular instance only exists the root user. The command should not be executed with root privileges (it executes mpirun, which is not recommended to run as sudo or the machine might break), so I was wondering if there is a way to block or disable the sudo privileges while the command is running. As mentioned, the only user existing there is root, so I suppose "sudo -u" is not an option.

Does anyone know how to do it? Thanks in advance!

  • There are no other users at all? Seems like a lot of stuff simply wouldn’t work without a single non-root user, not to mention this is a pretty bad security stance considering the only user is the most powerful one.

    If you do have another user on the instance you can su as that other user, nobody for example, from the root account. Run ‘cat /etc/passwd’ and you will see every available user on the instance.
