如何将参数传递给PowerShell脚本？

Question

有一个PowerShell名为的脚本itunesForward.ps1使iTunes快进30秒:

$iTunes = New-Object -ComObject iTunes.Application

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

它使用快速行命令执行:

powershell.exe itunesForward.ps1

是否可以从命令行传递参数并将其应用于脚本而不是硬编码的30秒值？

Answer 1

测试工作:

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
}

叫它

powershell.exe -file itunesForward.ps1 -step 15

Answer 2

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
}

然后它可以像这样调用:

powershell.exe -file itunersforward.ps1 15

让Powershell分析并确定数据类型在
内部为此使用'Variant'...
通常做得很好...

param( $x )
$iTunes = New-Object -ComObject iTunes.Application
if ( $iTunes.playerstate -eq 1 ) 
    { $iTunes.PlayerPosition = $iTunes.PlayerPosition + $x }

或者如果您需要传递多个参数

param( $x1, $x2 )
$iTunes = New-Object -ComObject iTunes.Application
if ( $iTunes.playerstate -eq 1 ) 
    { 
    $iTunes.PlayerPosition = $iTunes.PlayerPosition + $x1 
    $iTunes.<AnyProperty>  = $x2
    }

Answer 5

从Bath文件（* .bat）或CMD调用脚本

Powershell核心

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"

电源外壳

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"

从Powershell呼叫

Powershell Core或Windows Powershell

& path-to-script/Script.ps1 -Param1 Hello -Param2 World
& ./Script.ps1 -Param1 Hello -Param2 World

Script.ps1-脚本代码

param(
    [Parameter(Mandatory=$True, Position=0, ValueFromPipeline=$false)]
    [System.String]
    $Param1,

    [Parameter(Mandatory=$True, Position=1, ValueFromPipeline=$false)]
    [System.String]
    $Param2
)

Write-Host $Param1
Write-Host $Param2

Answer 6

在文件中使用以下代码创建 PowerShell 脚本。

param([string]$path)
Get-ChildItem $path | Where-Object {$_.LinkType -eq 'SymbolicLink'} | select name, target

这将创建一个带有路径参数的脚本。它将列出提供的路径中的所有符号链接以及符号链接的指定目标。
