OpenSSH on Windows 11: Alternatives to nohup, screen, and tmux for Running Programs in the Background
If you are using an OpenSSH server on a Windows 11 machine, you may need to run programs in the background, even after closing the PowerShell connection. This is a common task for system administrators and developers who want to run long-term tasks or schedule scripts to run at specific times.
Traditionally, Unix-based systems have used tools such as nohup, screen, and tmux to manage background programs. However, since Windows 10, OpenSSH has been included as a built-in feature, and these tools are not natively available on the Windows platform. This article will explore some alternatives for running programs in the background on a Windows 11 machine using OpenSSH.
Windows Task Scheduler
One of the most powerful and flexible alternatives for running programs in the background on a Windows 11 machine is the built-in Task Scheduler. The Task Scheduler can be configured to run a program or script at a specific time, on a recurring schedule, or in response to a specific event. This makes it a great option for running scheduled tasks or automating repetitive tasks.
To create a new task in the Task Scheduler, follow these steps:
- Open the Start menu and search for "Task Scheduler".
- Click on "Create Task" in the right sidebar.
- Enter a name and description for the task.
- Select the "Triggers" tab and click "New" to configure when the task should run.
- Select the "Actions" tab and click "New" to configure what program or script should be run.
- Click "OK" to save the task.
Once the task is created, it can be run manually or automated using a schedule or event trigger.
PowerShell Jobs
PowerShell provides a built-in mechanism for running programs in the background, called "jobs". A job is a background task that can be created and managed using PowerShell commands. Jobs can be created using the Start-Job cmdlet, which takes a script block as input. For example:
Start-Job -ScriptBlock { & "path\to\program.exe" }Once the job is created, it can be monitored using the Get-Job cmdlet. Jobs can be stopped or restarted using the Stop-Job and Restart-Job cmdlets, respectively. When the job is completed, its output can be retrieved using the Receive-Job cmdlet.
Jobs provide a simple and easy-to-use mechanism for running programs in the background on a Windows 11 machine using PowerShell.
Windows Services
Another option for running programs in the background on a Windows 11 machine is to create a Windows Service. A service is a long-running program that runs in the background and is started automatically when the system boots up. Services can be configured to run under a specific account, and can be managed using the built-in Services console.
To create a new service, follow these steps:
- Open the Start menu and search for "Windows Services".
- Click on "Turn Windows features on or off" and scroll down to "Remote Server Administration Tools".
- Expand "Remote Server Administration Tools" and check the box for "Role Administration Tools".
- Expand "Role Administration Tools" and check the box for "Windows Administration Tools".
- Click "OK" to install the tools.
- Open the Services console and click "Action" > "New" > "Service".
- Enter a name and description for the service.
- Select the account that the service should run under.
- Enter the path to the program or script that should be run.
- Configure any other settings as needed.
- Click "OK" to create the service.
Once the service is created, it can be started and stopped using the Services console.
In this article, we covered some alternatives for running programs in the background on a Windows 11 machine using OpenSSH. The Windows Task Scheduler, PowerShell jobs, and Windows Services are all powerful options for managing background tasks on a Windows 11 machine.
