For the root user's personal opinion in Linux-general Linux technology-Linux technology and application information, see the following for details. Linux may become as popular as Windows one day, and more users will be used, which is followed by security issues. Many people break Linux because they use root user operations.
Many articles require that you do not use the root user as a daily user. If the root user is not a root user, the impact scope will be small, especially on servers.
Here I think it is right. Usually, you can use ordinary users to perform operations, because some commands in Linux cannot recover data after misoperation, some people prefer to modify some files, so that the system may be directly damaged after the file is damaged, resulting in entry failure or re-installation.
We will be very secure without using root. Of course, the Linux Desktop is safe now, just in case.
