powershell - Invoke-Command 是否需要返回码

Question

Powershell 脚本

1. 在远程计算机上启用 PSRemoting
2. 在远程计算机上执行 setup.exe
3. 在远程计算机上禁用 PSRemoting

在远程计算机能够执行 setup.exe 后，如何确定我正在禁用 PSRemoting？

我是否在远程计算机能够执行 setup.exe 之前禁用 PSRemoting？

$password = get-content D:\Script\cred.txt | convertto-securestring
$credentials = new-object -typename System.Management.Automation.PSCredential -argumentlist "Administrator",$password
$j = "remote_computer"

$comp = "\\"+$j

$exe = "setup.exe"
[String]$cmd = "cmd /c 'C:\share\$exe'"
[ScriptBlock]$sb = [ScriptBlock]::Create($cmd) 


$bstr = [System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($password)
$str =  [System.Runtime.InteropServices.Marshal]::PtrToStringBSTR($bstr)
[System.Runtime.InteropServices.Marshal]::ZeroFreeBSTR($bstr)



$enable_command = "D:\PSTools\PsExec.exe $comp -u Administrator -p $str -accepteula powershell.exe c:\share\ps_enable.ps1"

Invoke-Expression $enable_command


try{
    invoke-command -ComputerName $j -Credential $credentials -ScriptBlock $sb

}
catch [System.Exception]{
    continue
}


$disable_command = "D:\PSTools\PsExec.exe $comp -u Administrator -p $str -accepteula powershell.exe c:\share\ps_disable.ps1"

Invoke-Expression $disable_command

Answer 1

很简单，使用 Invoke-Command 的 AsJob 开关并将其分配给一个变量。然后使用 Wait-Job 以便在继续禁用 PSRemoting 之前知道作业已完成。

try{
    $SetupJob = invoke-command -ComputerName $j -Credential $credentials -ScriptBlock $sb -AsJob

}
catch [System.Exception]{
    continue
}

$SetupJob|Wait-Job

$disable_command = "D:\PSTools\PsExec.exe $comp -u Administrator -p $str -accepteula powershell.exe c:\share\ps_disable.ps1"

Invoke-Expression $disable_command
