How to Launch Non-GUI Applications in Separate Command Windows with Golang on Windows?

Launching Separate Command Windows in Golang for Windows

In a Golang application that relies on the command window (CMD) for user interaction, it may become necessary to spawn additional instances of the application with their own dedicated command windows. While the os/exec package is initially a suitable choice, it falls short when attempting to launch non-GUI applications in separate windows.

Overcoming the Challenge

To successfully launch non-GUI applications in distinct command windows, a specific command syntax must be employed. This involves appending the start command after the cmd /c invocation. Here's how it's done:

<code class="go">package main

import (
    "exec"
    "fmt"
)

func main() {
    _path_to_executable_ := "C:\path\to\my_application.exe"

    // Create the command to start the application with a new window
    cmd := exec.Command("cmd", "/C", "start", _path_to_executable_)

    // Execute the command
    err := cmd.Start()
    if err != nil {
        fmt.Println(err)
    }
}</code>

By incorporating this modified command structure, the Golang application can successfully launch additional instances of itself in separate command windows, each with its own stdin and stdout.
