What is the root user and why shouldn't I use it all the time?
The root user is a super administrator account in the Unix-like system and has full access rights, but should not be used daily. Because it can cause misdeletion of files, system crashes or security vulnerabilities. For example, command errors can destroy the entire system, and ordinary user permissions can be used as security protection. In addition, most software is not designed to run as root, which may cause security risks. The root account exists for system-level modifications if necessary, such as installing software or adjusting network settings, but permissions should be temporarily obtained through sudo or UAC. The safe way to use root includes: prioritizing sudo instead of logging in directly to root; avoid running graphical interface programs with root; exiting the root session immediately after completing the operation; restricting the use of sudo to the user.
