如何将参数传递给PowerShell脚本? [英] How can I pass an argument to a PowerShell script?

问题描述

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

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
}

通过提示行命令执行:

powershell.exe itunesForward.ps1

是否可以从命令行传递参数并将其应用到脚本中，而不是硬编码的30秒值?

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?

推荐答案

经测试可正常工作:

param([Int32]$step=30) #Must be the first statement in your script

$iTunes = New-Object -ComObject iTunes.Application

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

用

powershell.exe -file itunesForward.ps1 -step 15
