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!

    Forgot to mention that creating a new user brings a lot of problems because of how that machine is configured and all the tools that would need to be added the new user’s permission. In theory it would eventually work after some time working on it, but I’d like to know if there’s a way to do it without creating users (or if it’s impossible, so I can just go on with that only option)

      You can run commands as the new user from the root account.
      su -c 'command' username
      Enter the password for the new user when prompted.
      This way at least the main account is still root and the command is being run without root privileges on the new users account.
