How to Launch a New Command Window from Golang in Windows

Launching a separate command window for an application can be challenging from within a Golang program. This question explores a common issue faced by developers who require multiple command windows with independent input and output streams.

Problem: Launching Non-GUI Applications with Separate Windows

The user is attempting to create a custom command window interface using a Go application. They have faced difficulty in launching a new instance of the application with its own window. Using the "os/exec" package has proved ineffective for non-GUI applications.

Solution: Using "start" Command in Windows

The solution lies in utilizing the "start" command as a suffix to "cmd /c" when executing the application. By leveraging the "./executor.exe /start C:/path/to/your/app.exe" format, the user can successfully launch a separate command window with its own standard input and output streams.

Here's the updated code that resolves the issue:

import (
    "os/exec"
)

func main() {
    cmd := exec.Command("cmd", "/C", "start", "./executor.exe", "/start", "C:/path/to/your/app.exe")
    err := cmd.Start()
    if err != nil {
        log.Fatal(err)  // Handle error
    }
}

This solution effectively creates a new command window for the specified application, complete with its own input and output facilities, allowing the Go program to interact with multiple command windows simultaneously.
