How can I execute a Windows command line in background?

Question

How can I execute a windows command line in the background, without it interacting with the active user?

Answer 1

Your question is pretty vague, but there is a post on ServerFault which may contain the information you need. The answer there describes how to run a batch file window hidden:

You could run it silently using a Windows Script file instead. The Run Method allows you running a script in invisible mode. Create a .vbs file like this one

Dim WinScriptHost
Set WinScriptHost = CreateObject("WScript.Shell")
WinScriptHost.Run Chr(34) & "C:\Scheduled Jobs\mybat.bat" & Chr(34), 0
Set WinScriptHost = Nothing

and schedule it. The second argument in this example sets the window style. 0 means "hide the window."

Answer 2

This is a little late but I just ran across this question while searching for the answer myself and I found this:

START /B program

which, on Windows, is the closest to the Linux command:

program &

From the console HELP system:

C:\>HELP START

Starts a separate window to run a specified program or command.

START ["title"] [/D path] [/I] [/MIN] [/MAX] [/SEPARATE | /SHARED]
      [/LOW | /NORMAL | /HIGH | /REALTIME | /ABOVENORMAL | /BELOWNORMAL]
      [/NODE <NUMA node>] [/AFFINITY <hex affinity mask>] [/WAIT] [/B]
      [command/program] [parameters]

    "title"     Title to display in window title bar.
    path        Starting directory.
    B           Start application without creating a new window. The
                application has ^C handling ignored. Unless the application
                enables ^C processing, ^Break is the only way to interrupt
                the application.

One problem I saw with it is that you have more than one program writing to the console window, it gets a little confusing and jumbled.

To make it not interact with the user, you can redirect the output to a file:

START /B program > somefile.txt

Answer 3

I suspect you mean: Run something in the background and get the command line back immediately with the launched program continuing.

START "" program

Which is the Unix equivalent of

program &

Answer 4

START /MIN program 

the above one is pretty closer with its Unix counterpart program &

Answer 5

You can use this (commented!) PowerShell script:

# Create the .NET objects
$psi = New-Object System.Diagnostics.ProcessStartInfo
$newproc = New-Object System.Diagnostics.Process
# Basic stuff, process name and arguments
$psi.FileName = $args[0]
$psi.Arguments = $args[1]
# Hide any window it might try to create
$psi.CreateNoWindow = $true
$psi.WindowStyle = 'Hidden'
# Set up and start the process
$newproc.StartInfo = $psi
$newproc.Start()
# Return the process object to the caller
$newproc

Save it as a .ps1 file. After enabling script execution (see Enabling Scripts in the PowerShell tag wiki), you can pass it one or two strings: the name of the executable and optionally the arguments line. For example:

.\hideproc.ps1 'sc' 'stop SomeService'

I confirm that this works on Windows 10.

Answer 6

This is how my PHP internal server goes into background. So technically it should work for all.

start /B "" php -S 0.0.0.0:8000 &

Thanks

A related answer, with 2 examples:

1. Below opens calc.exe:

call START /B "my calc" "calc.exe"

2. Sometimes foreground is not desireable, then you run minimized as below:

call start /min "n" "notepad.exe"

call START /MIN "my mongod" "%ProgramFiles%\MongoDB\Server\3.4\bin\mongod.exe"

Hope that helps.

Answer 8

If you want the command-line program to run without the user even knowing about it, define it as a Windows Service and it will run on a schedule.

Answer 9

You can see the correct way to do this in this link:

How to Run a Scheduled Task Without a Command Window Appearing

Summarizing, you have to checkbox for 'Run whether user is logged on or not'. Task user credentials should be enter after pressing 'Ok'.

just came across this thread windows 7 , using power shell, runs executable's in the background , exact same as unix filename &

example: start -NoNewWindow filename

help start
