Environment variables in Linux are essential components that store configuration data for processes running in the system. These variables can define system-wide settings like the location of system files or user-specific settings, such as paths to directories or API keys.

To see the value of an environment variable in Linux, you can use the following command in the terminal:

echo $VARIABLE_NAME

For example, to check the value of the PATH environment variable, you would run:

echo $PATH

If you want to list all environment variables, use the printenv or env command:

printenv

or

env

This will display a list of all environment variables along with their current values.

That's all, easy right?
