• How to add sudoers in Debian | FOSS Linux

  Sudo stands for superuser do. It is a command-line utility that permits trusted users to run commands as another user by default root. When prefixed with any command, the superuser temporarily gives another user rights as an alternative root. If you, for instance, want to access any system-related setting or, rather say, update a system or edit system files, you must log in as a “root” user in Linux. Ideally, root users have the right to perform any system task. However, sudo privileges can also be assigned to other users to act as a root. The basic philosophy is to give as few privileges as possible but still permit users to complete their work. Additionally, sudo is an effective way to log who ran which command and when. It is also advised to utilize this command carefully as it contains all the admin rights. As such, any misuse of the command may lead to severe damage to the system. In the latest release of Debian, version 11 (Bullseye), the sudo user’s info is stored in the sudoers file, located in the “/etc/sudoers” directory.
