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!

@ursakhiin honestly, didn't consider it. Just checked and the "docker" command doesn't even exist so I assume that is not the case. Do you know if the is any other way I can be certain?

@ursakhiin honestly, I didn't even know an aws instance could be a docker image. Everything I did was creating the instance normally so I assumed it was just a regular vm. But already double checked and it is not a docker image, so no problem there 🙂

@elscallr I agree about the instance configuration, fixing that is the real solution
My question was not about running something as another user, but about hiding the superadmin privileges from a single command I'd execute without switching users. However it is clear that something like that doesn't exist so I'll do the right thing and set everything to work with a new user
