In linux you can use command & to run command on the background, the same will continue after the shell is offline. I was wondering is there something like that for windows…
This question is related to
windows
cmd
background-process
The answer is
I'm assuming what you want to do is run a command without an interface (possibly automatically?). On windows there are a number of options for what you are looking for:
Best: write your program as a windows service. These will start when no one logs into the server. They let you select the user account (which can be different than your own) and they will restart if they fail. These run all the time so you can automate tasks at specific times or on a regular schedule from within them. For more information on how to write a windows service you can read a tutorial online such as (http://msdn.microsoft.com/en-us/library/zt39148a(v=vs.110).aspx).
Better: Start the command and hide the window. Assuming the command is a DOS command you can use a VB or C# script for this. See here for more information. An example is:
Set objShell = WScript.CreateObject("WScript.Shell") objShell.Run("C:\yourbatch.bat"), 0, TrueYou are still going to have to start the command manually or write a task to start the command. This is one of the biggest down falls of this strategy.
- Worst: Start the command using the startup folder. This runs when a user logs into the computer
Hope that helps some!
If you take 5 minutes to download visual studio and make a Console Application for this, your problem is solved.
using System;
using System.Linq;
using System.Diagnostics;
using System.IO;
namespace BgRunner
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Starting: " + String.Join(" ", args));
String arguments = String.Join(" ", args.Skip(1).ToArray());
String command = args[0];
Process p = new Process();
p.StartInfo = new ProcessStartInfo(command);
p.StartInfo.Arguments = arguments;
p.StartInfo.WorkingDirectory = Path.GetDirectoryName(command);
p.StartInfo.CreateNoWindow = true;
p.StartInfo.UseShellExecute = false;
p.Start();
}
}
}
Examples of usage:
BgRunner.exe php/php-cgi -b 9999
BgRunner.exe redis/redis-server --port 3000
BgRunner.exe nginx/nginx
You should also take a look at the at command in Windows. It will launch a program at a certain time in the background which works in this case.
Another option is to use the nssm service manager software. This will wrap whatever command you are running as a windows service.
UPDATE:
nssm isn't very good. You should instead look at WinSW project. https://github.com/kohsuke/winsw
Use the start command with the /b flag to run a command/application without opening a new window. For example, this runs dotnet run in the background:
start /b dotnet run
You can pass parameters to the command/application too. For example, I'm starting 3 instances of this C# project, with parameter values of x, y, and z:
To stop the program(s) running in the background: CTRL + BREAK
In my experience, this stops all of the background commands/programs you have started in that cmd instance.
According to the Microsoft docs:
CTRL+C handling is ignored unless the application enables CTRL+C processing. Use CTRL+BREAK to interrupt the application.
I believe the command you are looking for is start /b *command*
For unix, nohup represents 'no hangup', which is slightly different than a background job (which would be *command* &. I believe that the above command should be similar to a background job for windows.
