How to view the values of system variables in Linux?

In Linux systems, you can use the echo command to check the value of system variables. For example, to view the value of the PATH variable, you can enter the following command in the terminal:

echo $PATH

This will display the value of the PATH variable, which is the search path for all executable files in the system.

Additionally, you can use the printenv command to check the values of all system variables. Enter the following command:

printenv

This will list all system variables and their corresponding values.
