将整个脚本作为参数传递给powershell.exe

Question

I once found a script to easily change my Wallpaper if I use multiple ones.

set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.SendKeys("^ ")
WshShell.SendKeys("+{F10}")
WshShell.SendKeys("n")
WshShell.SendKeys("{ENTER}")

However I need a separate link that calls the script. Now I wonder if I can pass these multiple lines of code as parameter to powershell.exe directly.

I did read that I can allign multiple lines using ; and tried building the one-liner, however it doesn't run...or rather it does run, there is no feedback, nothing changes. If I paste the command line into a running powershell instance it just exits.

%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe -windowstyle hidden -Command "set WshShell = WScript.CreateObject('WScript.Shell'); WshShell.SendKeys('^ '); WshShell.SendKeys('+{F10}'); WshShell.SendKeys('n'); WshShell.SendKeys('{ENTER}')"

I basically just concatenated them and replaced the double quotes with single quotes to escape the special characters, so why does it not work as the separate script?

In PowerShell:

$WSH = New-Object -ComObject 'WScript.Shell'
$WSH.SendKeys('^ ')
$WSH.SendKeys('+{F10}')
$WSH.SendKeys('n')
$WSH.SendKeys('{ENTER}')

Save this as a script ( Filename.ps1 ), and call it from a .bat or .cmd file:

%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\powershell.exe -File "path\filename.ps1"

Alternatively, as a one-liner in a command file:

%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\powershell.exe -Command "$WSH = New-Object -ComObject 'WScript.Shell';$WSH.SendKeys('\^ ');$WSH.SendKeys('+{F10}');$WSH.SendKeys('n');$WSH.SendKeys('{ENTER}')"
