如何从批处理文件运行 PowerShell 脚本

Question

I am trying to run this script in PowerShell. I have saved the below script as ps.ps1 on my desktop.

$query = "SELECT * FROM Win32_DeviceChangeEvent WHERE EventType = 2"
Register-WMIEvent -Query $query -Action { invoke-item "C:\Program Files\abc.exe"}

I have made a batch script to run this PowerShell script

@echo off
Powershell.exe set-executionpolicy remotesigned -File  C:\Users\SE\Desktop\ps.ps1
pause

But I am getting this error:

Answer 1

You need the -ExecutionPolicy parameter:

Powershell.exe -executionpolicy remotesigned -File  C:\Users\SE\Desktop\ps.ps1

Otherwise PowerShell considers the arguments a line to execute and while Set-ExecutionPolicy is a cmdlet, it has no -File parameter.

Answer 2

I explain both why you would want to call a PowerShell script from a batch file and how to do it in my blog post here .

This is basically what you are looking for:

PowerShell -NoProfile -ExecutionPolicy Bypass -Command "& 'C:\Users\SE\Desktop\ps.ps1'"

And if you need to run your PowerShell script as an admin, use this:

PowerShell -NoProfile -ExecutionPolicy Bypass -Command "& {Start-Process PowerShell -ArgumentList '-NoProfile -ExecutionPolicy Bypass -File ""C:\Users\SE\Desktop\ps.ps1""' -Verb RunAs}"

Rather than hard-coding the entire path to the PowerShell script though, I recommend placing the batch file and PowerShell script file in the same directory, as my blog post describes.

Answer 3

如果要在没有完全限定路径的情况下从当前目录运行，可以使用：

PowerShell -NoProfile -ExecutionPolicy Bypass -Command "& './ps.ps1'"

Answer 4

If you run a batch file calling PowerShell as a administrator, you better run it like this, saving you all the trouble:

powershell.exe -ExecutionPolicy Bypass -Command "Path\xxx.ps1"

It is better to use Bypass ...

Small sample test.cmd

<# :
  @echo off
    powershell /nologo /noprofile /command ^
         "&{[ScriptBlock]::Create((cat """%~f0""") -join [Char[]]10).Invoke(@(&{$args}%*))}"
  exit /b
#>
Write-Host Hello, $args[0] -fo Green
#You programm...

If you want to run a few scripts, you can use Set-executionpolicy -ExecutionPolicy Unrestricted and then reset with Set-executionpolicy -ExecutionPolicy Default .

Note that execution policy is only checked when you start its execution (or so it seems) and so you can run jobs in the background and reset the execution policy immediately.

# Check current setting
Get-ExecutionPolicy

# Disable policy
Set-ExecutionPolicy -ExecutionPolicy Unrestricted
# Choose [Y]es

Start-Job { cd c:\working\directory\with\script\ ; ./ping_batch.ps1 example.com | tee ping__example.com.txt }
Start-Job { cd c:\working\directory\with\script\ ; ./ping_batch.ps1 google.com  | tee ping__google.com.txt  }

# Can be run immediately
Set-ExecutionPolicy -ExecutionPolicy Default
# [Y]es

Answer 7

Another easy way to execute a ps script from batch is to simply incorporate it between the ECHO and the Redirection characters,(> and >>), example:

@echo off
set WD=%~dp0
ECHO New-Item -Path . -Name "Test.txt" -ItemType "file" -Value "This is a text string." -Force > "%WD%PSHELLFILE.ps1"
ECHO add-content -path "./Test.txt" -value "`r`nThe End" >> "%WD%PSHELLFILE.ps1"
powershell.exe -ExecutionPolicy Bypass -File "%WD%PSHELLFILE.ps1"
del "%WD%PSHELLFILE.ps1"

Last line deletes the created temp file.

如果您的 PowerShell 登录脚本在 2012 年服务器上运行 5 分钟（就像我的一样），则服务器上有一个 GPO 设置-“配置登录脚本延迟”默认设置“未配置”这将留下 5 分钟的延迟在运行登录脚本之前。

Following this thread:
https://community.idera.com/database-tools/powershell/powertips/b/tips/posts/converting-powershell-to-batch


you can convert any PowerShell script into a batch file easily using this PowerShell function:

function Convert-PowerShellToBatch
{
    param
    (
        [Parameter(Mandatory,ValueFromPipeline,ValueFromPipelineByPropertyName)]
        [string]
        [Alias("FullName")]
        $Path
    )
 
    process
    {
        $encoded = [Convert]::ToBase64String([System.Text.Encoding]::Unicode.GetBytes((Get-Content -Path $Path -Raw -Encoding UTF8)))
        $newPath = [Io.Path]::ChangeExtension($Path, ".bat")
        "@echo off`npowershell.exe -NoExit -encodedCommand $encoded" | Set-Content -Path $newPath -Encoding Ascii
    }
}

To convert all PowerShell scripts inside a directory, simply run the following command:

Get-ChildItem -Path <DIR-PATH> -Filter *.ps1 |
  Convert-PowerShellToBatch

Where is the path to the desired folder. For instance:

Get-ChildItem -Path "C:\path\to\powershell\scripts" -Filter *.ps1 |
  Convert-PowerShellToBatch

To convert a single PowerShell script, simply run this:

Get-ChildItem -Path <FILE-PATH> |
  Convert-PowerShellToBatch

Where is the path to the desired file.

The converted files are located in the source directory. ie, <FILE-PATH> or <DIR-PATH> .

Putting it all together:
create a .ps1 file (PowerShell script) with the following code in it:

function Convert-PowerShellToBatch
{
    param
    (
        [Parameter(Mandatory,ValueFromPipeline,ValueFromPipelineByPropertyName)]
        [string]
        [Alias("FullName")]
        $Path
    )
 
    process
    {
        $encoded = [Convert]::ToBase64String([System.Text.Encoding]::Unicode.GetBytes((Get-Content -Path $Path -Raw -Encoding UTF8)))
        $newPath = [Io.Path]::ChangeExtension($Path, ".bat")
        "@echo off`npowershell.exe -NoExit -encodedCommand $encoded" | Set-Content -Path $newPath -Encoding Ascii
    }
}

# change <DIR> to the path of the folder in which the desired powershell scripts are.
# the converted files will be created in the destination path location (in <DIR>).
Get-ChildItem -Path <DIR> -Filter *.ps1 |
  Convert-PowerShellToBatch

And don't forget, if you wanna convert only one file instead of many, you can replace the following

Get-ChildItem -Path <DIR> -Filter *.ps1 |
  Convert-PowerShellToBatch

with this:

Get-ChildItem -Path <FILE-PATH> |
  Convert-PowerShellToBatch

as I explained before.
