- What files do Linux environment variables come from?
- In the Linux environment, after the LinuxShell login is successful, Linux will obtain a series of data from the file for the login. This data will be used in individual instructions or individual programs. That data is called the LinuxShell runtime environment. Data in the environment can be roughly divided into four types: environment variables, Shell variables, aliases, and Shell functions. Among them, Shell variables, aliases, and Shell functions will not be explained in detail here. What are the environment variables? You can directly use the printenv command without parameters to output the environment variables of the current session and the values of the environment variables.
