From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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, 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 🙂

It's not that an Amazon instance can be a docker container. It was more that the behavior you are describing is extremely odd for a full Linux environment but normal for a docker container.

If you created the instance, it isn't likely a container. But it also sounds like the base image might be poorly set up
