有一个名为itunesForward的PowerShell脚本。让iTunes快进30秒的ps1:
$iTunes = New-Object -ComObject iTunes.Application
if ($iTunes.playerstate -eq 1)
{
$iTunes.PlayerPosition = $iTunes.PlayerPosition + 30
}
它由提示行命令执行:
powershell.exe itunesForward.ps1
是否有可能从命令行传递一个参数，并将其应用到脚本中，而不是硬编码的30秒值?
当前回答
你也可以使用$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
}
然后可以这样调用:
powershell.exe -file itunersforward.ps1 15

从批处理文件(*.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"
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"
powershell.exe -NoLogo -ExecutionPolicy Bypass -Command "./Script.ps1 Hello -Param2 World"
powershell.exe -NoLogo -ExecutionPolicy Bypass -Command "./Script.ps1 Hello World"
powershell.exe -NoLogo -ExecutionPolicy Bypass -Command "./Script.ps1 -Param2 World Hello"
从PowerShell调用
PowerShell Core或Windows PowerShell
& path-to-script/Script.ps1 -Param1 Hello -Param2 World
& ./Script.ps1 -Param1 Hello -Param2 World
脚本。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 $Param2
在文件中使用以下代码创建一个PowerShell脚本。
param([string]$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。它将列出所提供路径中的所有符号链接以及符号链接的指定目标。
让PowerShell分析并决定数据类型。它在内部使用了一个“变体”。
总的来说，它做得很好……
param($x)
$iTunes = New-Object -ComObject iTunes.Application
if ($iTunes.playerstate -eq 1)
{
$iTunes.PlayerPosition = $iTunes.PlayerPosition + $x
}
或者如果你需要传递多个参数:
param($x1, $x2)
$iTunes = New-Object -ComObject iTunes.Application
if ($iTunes.playerstate -eq 1)
{
$iTunes.PlayerPosition = $iTunes.PlayerPosition + $x1
$iTunes.<AnyProperty> = $x2
}

[String] $site,
[Parameter(Mandatory=$True)]
[String] $application,
[Parameter(Mandatory=$True)]
[String] $dir,
[Parameter(Mandatory=$True)]
[String] $applicationPool
)

CreateDirectory($fullDir)

$fullWebSiteDir = GetWebSiteDir($Site)f($null -ne $fullWebSiteDir)
{

}
