[Golang] execute long running job and streaming the realtime output

main.go

func main() {
	cmd := exec.Command("sh", "-c", "cd ../../bin/worker; ./run.sh")
    // some command output will be input into stderr
    // e.g.
    // cmd := exec.Command("../../bin/master_build")
    // stderr, err := cmd.StderrPipe()
	stdout, err := cmd.StdoutPipe()
	if err != nil {
		fmt.Println(err)
	}

	err = cmd.Start()
	fmt.Println("The command is running")
	if err != nil {
		fmt.Println(err)
	}
	
	// print the output of the subprocess
	scanner := bufio.NewScanner(stdout)
	for scanner.Scan() {
		m := scanner.Text()
		fmt.Println(m)
	}
	cmd.Wait()
}

Any idea on how to do this in Windows? Windows flushes all the logs at once in the end

thx for this

Did you ever figure this out?

Not sure if anyone is still looking for a solution, but I found that this project seems to work well as a wrapper for os/exec that supports streaming output from a go routine.

nobody search a thing like that :) not tested but thx.
