It should also be mentioned  that Set-PSDebug is similar to the old-school echo on batch command  Set-PSDebug -Trace 1  This command will result in showing every line of the executing script   When the Trace parameter has a value of 1  each line of script is traced as it runs  When the parameter has a value of 2  variable assignments  function calls  and script calls are also traced  If the Step parameter is specified  you re prompted before each line of the script runs
