Tested as working:
#Must be the first statement in your script (not coutning comments) param([Int32]$step=30) $iTunes = New-Object -ComObject iTunes.Application if ($iTunes.playerstate -eq 1) { $iTunes.PlayerPosition = $iTunes.PlayerPosition + $step }
Call it with
powershell.exe -file itunesForward.ps1 -step 15
Multiple parameters syntax (comments are optional, but allowed):
<# Script description. Some notes. #> param ( # height of largest column without top bar [int]$h = 4000, # name of the output image [string]$image = 'out.png' )
And some example for advanced parameters, e.g. Mandatory:
<# Script description. Some notes. #> param ( # height of largest column without top bar [Parameter(Mandatory=$true)] [int]$h, # name of the output image [string]$image = 'out.png' ) Write-Host "$image $h"
A default value will not work with a mandatory parameter. You can omit the =$true
for advanced parameters of type boolean [Parameter(Mandatory)]
