在Powershell脚本中运行.bat而不打开任何窗口

Question

I have written a PowerShell script that is going to interpret a mail's body for command's and create a .bat file to execute the commando's it found. This script works, but the one big issues is that whenever is executes the .bat file, a command-prompt window flashes over the screen real quick. I was wondering if it's possible to prevent this from happening?

My code:

$m.Body | Out-File cmd.bat -Encoding ascii -Append
.\cmd.bat | Out-File results.txt

Is there any command of property i have to set? Thanks.

Answer 1

Answers and information can be found here .

From there, the selected answer, in case the link goes stale:

Save the following as wscript, for instance, hidecmd.vbs after replacing "testing.bat" with your batch file's name.

Set oShell = CreateObject ("Wscript.Shell") 
Dim strArgs
strArgs = "cmd /c testing.bat"
oShell.Run strArgs, 0, false

The second parameter of oShell.Run is intWindowStyle value indicating the appearance of the program's window and zero value is for hidden window.

Answer 2

I realize this question is more than 2 years old at the time I write this however there is still no official answer. Although I am very new to PowerShell, I think I have a more pure Powershell answer than using vbscript or COM.

Use Invoke Command:

Invoke-Command {cmd.exe /c cmd.bat} | Out-File results.txt

That Should do the trick. This will shell to cmd.exe and the /c will self terminate the shell on completion. It will run within the current shell so no new window will open.
