Powershell上运行psexec

Question

我想在Powershell上运行psexec命令。我在Windows命令处理器上运行了这一行，它工作。

$computers = gc "C:\temp\scripts\computers.txt" 
foreach ($computer in $computers) 
{ 
    if (test-Connection -Cn $computer -quiet) { 
     & C:\temp\sysinternals\psexec.exe \\$computer "C:\Temp\CMA4.5\frminst.exe/forceuninstall/silent" 
    }else { 
    "$computer is not online" 
    } 
} 

这是我收到的错误：

psexec.exe : At C:\temp\Scripts\CopyFiles.ps1:19 char:9 
+   & C:\temp\sysinternals\psexec.exe \\$computer "C:\Temp\CMA4.5\frminst.ex ...

Answer 1

尝试传递参数给PsExec这样：

$computers = gc "C:\temp\scripts\computers.txt" 
foreach ($computer in $computers) 
{ 
    if (test-Connection -Cn $computer -quiet) { 
     & 'C:\temp\sysinternals\psexec.exe' @("\\$computer", 'C:\Temp\CMA4.5\frminst.exe', '/forceuninstall', '/silent') 
    }else { 
    "$computer is not online" 
    } 
} 

这是一个PowerShell的秘密。如果您指定了一个值数组，它会自动将它们扩展为单独的参数。在99.99％的情况下，这将起作用，并将您从丑陋的字符串连接中解脱出来，并将引号混淆。
