There's a PowerShell script named itunesForward.ps1
that makes iTunes fast forward 30 seconds:
$iTunes = New-Object -ComObject iTunes.Application
if ($iTunes.playerstate -eq 1)
{
$iTunes.PlayerPosition = $iTunes.PlayerPosition + 30
}
It is executed with a prompt line command:
powershell.exe itunesForward.ps1
Is it possible to pass an argument from the command line and have it applied in the script instead of the hardcoded 30 seconds value?

Create a PowerShell script with the following code in the file.
param([string]$path)
Get-ChildItem $path | Where-Object {$_.LinkType -eq 'SymbolicLink'} | select name, target
This creates a script with a path parameter. It will list all symbolic links within the path provided as well as the specified target of the symbolic link.
Call the script from a batch file (*.bat) or CMD
pwsh.exe -NoLogo -ExecutionPolicy Bypass -Command "./Script.ps1 -Param1 Hello -Param2 World"
pwsh.exe -NoLogo -ExecutionPolicy Bypass -Command "path-to-script/Script.ps1 -Param1 Hello -Param2 World"
pwsh.exe -NoLogo -ExecutionPolicy Bypass -Command "./Script.ps1 Hello -Param2 World"
pwsh.exe -NoLogo -ExecutionPolicy Bypass -Command "./Script.ps1 Hello World"
pwsh.exe -NoLogo -ExecutionPolicy Bypass -Command "./Script.ps1 -Param2 World Hello"
PowerShell
powershell.exe -NoLogo -ExecutionPolicy Bypass -Command "./Script.ps1 -Param1 Hello -Param2 World"
powershell.exe -NoLogo -ExecutionPolicy Bypass -Command "path-to-script/Script.ps1 -Param1 Hello -Param2 World"

You can also define a variable directly in the PowerShell command line and then execute the script. The variable will be defined there, too. This helped me in a case where I couldn't modify a signed script.
Example:
PS C:\temp> $stepsize = 30
PS C:\temp> .\itunesForward.ps1
with iTunesForward.ps1 being
$iTunes = New-Object -ComObject iTunes.Application
if ($iTunes.playerstate -eq 1)
{
$iTunes.PlayerPosition = $iTunes.PlayerPosition + $stepsize
}
You can use also the $args
variable (that's like position parameters):
$step = $args[0]
$iTunes = New-Object -ComObject iTunes.Application
if ($iTunes.playerstate -eq 1)
{
$iTunes.PlayerPosition = $iTunes.PlayerPosition + $step
}
Then it can be called like:
powershell.exe -file itunersforward.ps1 15
Let PowerShell analyze and decide the data type. It internally uses a 'Variant' for this.
And generally it does a good job...
param($x)
$iTunes = New-Object -ComObject iTunes.Application
if ($iTunes.playerstate -eq 1)
{
$iTunes.PlayerPosition = $iTunes.PlayerPosition + $x
}
Or if you need to pass multiple parameters:
param($x1, $x2)
$iTunes = New-Object -ComObject iTunes.Application
if ($iTunes.playerstate -eq 1)
{
$iTunes.PlayerPosition = $iTunes.PlayerPosition + $x1
$iTunes.<AnyProperty> = $x2
}
