Question

我正在尝试在Powershell上运行psexec命令。我在Windows命令处理器上运行了这一行并且它运行良好。

$computers = gc "C:\temp\scripts\computers.txt" 
foreach ($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"
    } 
}

这是我得到的错误：

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

尝试以这种方式将参数传递给PsExec：

$computers = gc "C:\temp\scripts\computers.txt" 
foreach ($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PowerShell的秘密。如果指定值数组，它将自动将它们扩展为单独的参数。在99.99％的情况下，这将起作用并使您免于丑陋的字符串连接和弄乱引号。
