Powershell 调用命令

问题描述

我写这个脚本是为了在远程机器上执行命令。如果我不带参数输入它，它运行良好

PS D:\batch>  .\remoteExecute.ps1 -computer myServer -command 'dir'

Directory: C:\Users\AC0476BF\Documents

Mode                LastWriteTime         Length Name                                  PSComputerName                       
----                -------------         ------ ----                                  --------------
-----        5/31/2021   4:27 PM                WindowsPowerShell                     myServer                  

Executing: 'dir' on remote computer myServer

然而，如果我指定一个参数，它会返回一个错误。

PS D:\batch>  .\remoteExecute.ps1 -computer myserver -command 'dir c:\windows'
The term 'dir c:\windows' is not recognized as the name of a cmdlet,function,script file,or operable program. Check the spelling of the name,or if a path was included,verify that the path is correct and try again.
    + CategoryInfo          : ObjectNotFound: (dir c:\windows:String) [],CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException
    + PSComputerName        : myServer
 
Executing: 'dir c:\windows' on remote computer myServer

我错过了什么？

param (
    [Parameter(Mandatory = $true,HelpMessage = "Remote computer")]
    [String]$computer,[Parameter(Mandatory = $true,HelpMessage = "Command to be executed on the remote computer")]
    [String]$command,[Parameter(Mandatory = $false,HelpMessage = "Logging of command enabled to filename specified")]
    [String]$logFile,HelpMessage = "Execute in Command Shell. Default is PowerShell")]
    [Switch]$cmdshell
)
 
try {
    if ($cmdshell) {
        $command = "cmd --% /c '" + $command + "'"
    }

    if ($logFile) {
        $executeCommand = $command + " *>> " + $logfile
    }
    else {
        $executeCommand = $command
    }

    Invoke-Command -computerName $computer -ScriptBlock { & $using:executeCommand } 
                
    $message = "Executing: '" + $executeCommand + "' on remote computer " + $computer
    Write-Host $message

   
    exit 0
}
catch {
    $message = $PSItem.ToString()
    Write-Host $message
    # logging goes here...
    throw     
}
