the difference between a user variable and a system variable:

A: User variable: The environment variable is valid after the user logs on.

system variable: refers to any user who logs on to the system, and the environment variable is valid.

How to use: to determine whether the environment variable is sensitive or whether there are user restrictions, if not configured in the system variables, otherwise, according to the sensitivity or restrictions on the configuration of the user's environment variables, is conducive to security.

6, the command is commonly used
