Related introduction:

Since the 1980s, every popular operating system has supported variables, just like programming languages. When a process starts, it inherits the variables of the parent process. The process uses these variables to discover information about the environment in which it is run, such as the preferred location for saving temporary files or the location of the user's home directory.

If you are using a Unix operating system, such as MacOS or Linux, you can open a terminal and view the value of the $HOME environment variable, as shown below:

» echo $HOME /Users/matt

If you are using Windows , you can open Powershell and enter the following:

Write-Output $env:HOMEPATH

Typically, environment variables are written in uppercase, with underscores separating the words LIKE_THIS.
