How to declare global variables in PowerShell

To declare a global variable in PowerShell, you can use the $global: scope modifier before the variable name.

For example, to declare a global variable named $myVariable, you would use the following syntax:

$global:myVariable = "Hello, world!"

You can then access the global variable from anywhere in your PowerShell script or session by simply referencing its name, without the $global: scope modifier:

Write-Output $myVariable

This would output the string "Hello, world!" to the console.

Global variables should be used with caution, as they can potentially cause conflicts or unexpected behavior in your scripts.

In general, it's best to use global variables only when you have a specific need for them, and to avoid using them unnecessarily.
