For example, to access the value of the PATH environment variable, you would use $env:PATH. You can also set the value of an environment variable using the same syntax. Additionally, you can list all available environment variables by using the Get-ChildItem Env: command in PowerShell. This will display a list of all defined environment variables along with their values.
