We can see what some of these are set to using nothing more sophisticated than echo, which will write the values to the terminal window.

TERM: Terminal windows are actually emulations of a hardware terminal. This holds the type of hardware terminal that will be emulated.On most Linux distributions, this will be bash unless you changed it from the default. SHELL: The name of the shell that will launch when you open a terminal window.Global Environment Variablesīy convention, environment variables are given uppercase names. Here are some of the global environment variables, and what the values they contain represent: So, if you alter the command prompt in the current shell, and then launch a child shell, the child shell won’t inherit the modified command prompt of the parent. If the child process is a shell, that shell will initialize from its own, fresh, set of variables. When a program or command is launched from that shell-known as a child process-it inherits the environment of the parent process-but watch out! As we’ll see, you can create variables that don’t get added to your environment, so they won’t be inherited by a child process. It’s at this point that it reads the environment variables that define the environment of the shell. When a shell starts, it goes through an initialization phase.
We’ll also show you how to make them available to child processes and to be persistent across reboots. We’re going to show you how to see the environment variables that exist on your system, and we’ll describe how to create your own. Your locale, time zone, and keyboard settings, the set of directories searched when the shell tries to find a command, and your default editor, are all stored in shell environment variables. There’s a third set of environment variables defined within the shell. Others can’t reference your session environment variables. Others are session-wide and can only be seen by you. Some environment variables are system-wide, or global. So, naturally, they’re referred to as environment variables. Collectively, these variables hold settings that define the environment you find inside your terminal window, right down to the look of the command prompt. These variables also ensure that any information to which the terminal window and shell might need to refer is available. When you launch a terminal window and the shell inside it, a collection of variables is referenced to ensure the shell is configured correctly.
