What Does the “$” Symbol Do In Powershell?

In PowerShell, the "$" symbol is used to denote a variable. Variables in PowerShell are used to store data or values that can be referenced or manipulated in a script. When the "$" symbol is used before a word or combination of characters, it indicates that it is a variable. The value stored in the variable can then be accessed or modified throughout the script. Variables in PowerShell are typically used to store information such as file paths, user input, or other data that is needed for the script to execute properly.

To check if a folder exists in PowerShell, you can use the Test-Path cmdlet.

Here's an example:

$folderPath = "C:\Path\To\Folder"

if (Test-Path $folderPath -PathType Container) {

} else {
    Write-Host "Folder does not exist."
}

In this code snippet, replace "C:\Path\To\Folder" with the path of the folder you want to check. The Test-Path cmdlet with the -PathType parameter set to Container will return true if the folder exists and false if it does not exist.
