Modify a script to accept parameters

Q. How can I modify a script to accept a parameter?

A. Enabling a script to accept a parameter requires only a single line to added to script:

Param([Parameter(ValuefromPipeline=$true,Mandatory=$true)][string]$user)

In this example the value passed to the script is stored in variable $user and must be passed and can also be passed along the pipeline. Below is an example use:

Param([Parameter(ValuefromPipeline=$true,Mandatory=$true)][string]$user)$AdObj = New-Object System.Security.Principal.NTAccount($user)$strSID = $AdObj.Translate([System.Security.Principal.SecurityIdentifier])$strSID.Value

Once saved as FindADUserSID.ps1 it can be used in a number of ways:
