PowerShell: Drop (remove) the last character from a string

Drop (remove) the last character from a string:

$ComputerName = ‘DCCOMP01$’
$ComputerName = $ComputerName.Substring(0,$ComputerName.Length-1)
$ComputerName

Result is “DCCOMP01″.
This works especially well when the last character is a special PowerShell reserved one like “$”.
