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.
If a different user doesn’t exist then you obviously can’t run the command as that different user. The only solution here is to create a new user account.
Also your image is improperly configured which is something you should fix first.
