检查命令是否成功运行 [英] Check if a command has run successfully

问题描述

我已尝试将以下内容包含在 if 语句中，以便在成功时执行另一个命令:

I've tried enclosing the following in an if statement so I can execute another command if this succeeds:

Get-WmiObject -Class Win32_Share -ComputerName $Server.name -Credential $credentials -Filter "Description='Default share'" | Foreach-Object {
        $Localdrives += $_.Path

但是我不知道该怎么做.我什至尝试创建一个函数，但我也不知道如何检查该函数是否已成功完成.

but I can't figure out how to do it. I even tried creating a function but I couldn't figure out how to check if the function had successfully completed either.

推荐答案

你可以试试:

$res = get-WmiObject -Class Win32_Share -Filter "Description='Default share'"
if ($res -ne $null)
{
  foreach ($drv in $res)
  {
    $Localdrives += $drv.Path
  }
}
else
{
  # your error
}
