Creating .bat file with e-mail body in Powershell

I'm currently working on a script which will read a mail from a certain sender, who will be sending some commands for the scripts to run.

The Main Idea:

Sender sends a mail with a command for example: ipconfig /all > result.txt and the script running at the recipients side copies this command to a .bat file and running the .bat file to process the command.

The Code:

$junk = $routlook.GetDefaultFolder(23)
$MI = $junk.items

foreach($m in $MI)
{
    if($m.SenderEmailAddress -eq '<sender-address>')
    {
        Echo "@ECHO OFF" > com.bat
        Echo $MI.item(1).Body > com.bat
        .\com.bat
    }
    break
}

The Error:

Solution

  • Your problem is that you are not specifying the encoding of your output file.

    The easiest way to fix this is to use the Out-File cmdlet and specify the encoding yourself. Note that the 2nd and subsequent calls to Out-File must specify the -Append parameter or you will overwrite your file.

    $> "@ECHO OFF" | Out-File -FilePath cmd.bat -Encoding ascii
$> "Echo hi"   | Out-File -FilePath cmd.bat -Encoding ascii -Append
$> .\cmd.bat
