使用Golang在Windows上启动分离过程

I have a Golang code which must run a detached child process.

The Linux version of my implementation using syscall.ForkExec like this.

syscall.ForkExec(my_program, []string{}, nil)

But I can't found Windows implementation. I have found a proposition using START /B.

cmd := exec.Command("START", "/B", my_program)
cmd.Start()

Unfortunately, START can't be found and I have no other solution using Golang.

    start is not a standalone application, it's an (internal) command of the Windows command line interpreter (cmd.exe) (details: Command line reference / Start), so you need a "shell" to run the start command.

    Use cmd.exe with the /C parameter, and pass start and your application to run.

    Like in this example:

    s := []string{"cmd.exe", "/C", "start", `c:\path\to\your\app\myapp.exe`}
    
    cmd := exec.Command(s[0], s[1:]...)
    if err := cmd.Run(); err != nil {
        log.Println("Error:", err)
    }
    

    Or without the command slice:

    cmd := exec.Command("cmd.exe", "/C", "start", `c:\path\to\your\app\myapp.exe`)
    if err := cmd.Run(); err != nil {
        log.Println("Error:", err)
    }
    

    You may also pass the /b param to start like this if you don't want a terminal window for the launched application:

    cmd := exec.Command("cmd.exe", "/C", "start", "/b", `c:\path\to\your\app\myapp.exe`)
    if err := cmd.Run(); err != nil {
        log.Println("Error:", err)
    }
