PowerShell Variables in PowerShell Removing a variable
Example
To remove a variable from memory, one can use the Remove-Item cmdlet. Note: The variable name does NOT include the $.
Remove-Item Variable:\foo
Variable has a provider to allow most *-item cmdlets to work much like file systems.
Another method to remove variable is to use Remove-Variable cmdlet and its alias rv
$var = "Some Variable" #Define variable 'var' containing the string 'Some Variable'
$var #For test and show string 'Some Variable' on the console
Remove-Variable -Name var
$var
#also can use alias 'rv'
rv var
