Ever worried about other users on your Linux server seeing what processes are running? The `hidepid` kernel feature is your friend! It makes processes invisible to anyone but the owner and root user, even in system monitoring tools like ps, top, htop, and btop. This is a great way to prevent sensitive information (like API keys or passwords used in command-line arguments) from being exposed. See how to configure it www.cyberciti.biz/faq/linux-hide-processes-from-other-users for more info. #linux #opensource #security
