Question

我修改了我从Microsoft论坛获得的一个函数，其目的是将bat文件复制到远程计算机并在那里运行。我可以看到正在复制的文件，但是当我尝试调用Invoke-Command来执行文件时，它似乎无法正常工作。任何建议将不胜感激，谢谢:)

function Run-BatchFile ($computer, [string]$batLocation)
{

    $sessions = New-PSSession -ComputerName $computer -Credential qa\qalab3
    Copy-Item -Path $batLocation -Destination "\\$computer\C$\MD5temp" #copy the file locally on the machine where it will be executed
    $batfilename = Split-Path -Path $batLocation -Leaf
    Invoke-Command -Session $sessions -ScriptBlock {param($batfilename) "cmd.exe /c C:\MD5temp\$batfilename" } -ArgumentList $batfilename -AsJob
     $remotejob | Wait-Job #wait for the remote job to complete     
    Remove-Item -Path "\\$computer\C$\MD5temp\$batfilename" -Force #remove the batch file from the remote machine once job done
    Remove-PSSession -Session $sessions #remove the PSSession once it is done
}

Run-BatchFile 192.168.2.207 "D:\MD5Check\test.bat"

您将命令行设置为在引号中运行。

Invoke-Command -Session $sessions -ScriptBlock {
  param($batfilename)
  "cmd.exe /c C:\MD5temp\$batfilename"
} -ArgumentList $batfilename -AsJob

PowerShell只会回显裸字符串，而不是将它们解释为命令并执行它们。您需要使用Invoke-Expression作为后者：

Invoke-Command -Session $sessions -ScriptBlock {
  param($batfilename)
  Invoke-Expression "cmd.exe /c C:\MD5temp\$batfilename"
} -ArgumentList $batfilename -AsJob

或（更好）删除引号并（可选）使用调用运算符：

Invoke-Command -Session $sessions -ScriptBlock {
  param($batfilename)
  & cmd.exe /c "C:\MD5temp\$batfilename"
} -ArgumentList $batfilename -AsJob
