PowerShell command prints the value rather than executing

Question

I have written a power shell command to achieve a specific function and I'm new to power shell. That should perform the action and I'm pretty sure I have entered exact working command. But when I try to execute the command inside for each loop, it prints the command rather than executing. NWAdminCommand is my command and it gets values from user input.

$NWAdminCommand = Read-Host "Enter NWAdmin Command to perform request action"

foreach ($SPSite in $spWebApp.Sites)
    {

      foreach($SPWeb in $SPSite.AllWebs)
         {
    $NWAdminCommand;
         }
     } 
    }

You have an extra } (last one) you should remove it... – Oscar Foley Aug 13 '14 at 07:54 — Oscar Foley, Aug 13 '14 at 07:54

This line $NWAdminCommand is equivalent to Write-Host $NWAdminCommand. In order to execute a command you can prefix it with & or use iex.

 & $NWAdminCommand
 iex $NWAdminCommand

You can check this SO question or this Microsoft Technet web page that explains all the different ways of executing commands.

This is the correct code (assumming that $spWebApp.Sites and $SPSite.AllWebs are not empty collections)

$NWAdminCommand = Read-Host "Enter NWAdmin Command to perform request action"
foreach ($SPSite in $spWebApp.Sites)
{
      foreach($SPWeb in $SPSite.AllWebs)
      {
            & $NWAdminCommand
            #iex $NWAdminCommand
      }
}
