如何将参数传递给PowerShell脚本？

There's a PowerShell script named itunesForward.ps1 that makes the iTunes fast forward 30 seconds:

有一个名为itunesForward.ps1的PowerShell脚本使iTunes快进30秒：

$iTunes = New-Object -ComObject iTunes.Application

if ($iTunes.playerstate -eq 1)
{
  $iTunes.PlayerPosition = $iTunes.PlayerPosition + 30
}

It is executed with prompt line command:

它使用快速行命令执行：

powershell.exe itunesForward.ps1

Is it possible to pass an argument from the command line and have it applied in the script instead of hardcoded 30 seconds value?

是否可以从命令行传递参数并将其应用于脚本而不是硬编码的30秒值？

You can use also $args variable (that's like position parameters):

你也可以使用$ args变量（就像位置参数一样）：

$step=$args[0]

$iTunes = New-Object -ComObject iTunes.Application

if ($iTunes.playerstate -eq 1)
{
  $iTunes.PlayerPosition = $iTunes.PlayerPosition + $step
}

then it can be call like:

然后它可以像这样调用：

powershell.exe -file itunersforward.ps1 15
