How can I test that a variable is more than eight characters in PowerShell

Question

How do test if the number of characters in  dbUserName is more than eight characters   I have been unable to locate a command or series of commands that will let me do this  I have only been able to find if the variable is null   if   dbUserName        Write-Output   You left Username blank       dbUserName   read-host     But I would like to next test like this   if   dbUserName  String   gt  8         Write-Output   Please enter more than 8 characters        dbUserName read-host   Re-enter database user name

You can also use -match against a Regular expression. Ex:

if ($dbUserName -match ".{8}" )
{
    Write-Output " Please enter more than 8 characters "
    $dbUserName=read-host " Re-enter database user name"
}

Also if you're like me and like your curly braces to be in the same horizontal position for your code blocks, you can put that on a new line, since it's expecting a code block it will look on next line. In some commands where the first curly brace has to be in-line with your command, you can use a grave accent marker (`) to tell powershell to treat the next line as a continuation.

Use the length property of the  String  type   if   dbUserName length -gt 8        Write-Output  Please enter more than 8 characters        dbUserName   Read-Host  Re-enter database username      Please note that you have to use -gt instead of  gt  in your if condition  PowerShell uses the following comparison operators to compare values and test conditions    -eq   equals -ne   not equals -lt   less than -gt   greater than -le   less than or equals -ge   greater than or equals
