Variable commands

A number of commands are available to interact with variables:

• Clear-Variable
• Get-Variable
• New-Variable
• Remove-Variable
• Set-Variable

Clear-Variable

Clear-Variable removes the value from any existing variable. Clear-Variable does not remove the variable itself. For example, the following example calls Write-Host twice: the first time it writes the variable value; the second time it does not write anything:

PS> $temporaryValue = "Some-Value"
Write-Host $temporaryValue -ForegroundColor Green

Some-Value

PS> Clear-Variable temporaryValue
Write-Host $temporaryValue -ForegroundColor Green

Get-Variable
