Start (and kill) a command with arguments from go

command.go

package main

import (
	"log"
	"os/exec"
	"time"
)

func main() {
	// Start a process:
	cmd := exec.Command("omxplayer.bin", "--layout", "5.1", "crossbones2.ogg")
	if err := cmd.Start(); err != nil {
		log.Fatal(err)
	}

	// Wait for the process to finish or kill it after a timeout (whichever happens first):
	done := make(chan error, 1)
	go func() {
		done <- cmd.Wait()
	}()
	select {
	case <-time.After(60 * time.Second):
		if err := cmd.Process.Kill(); err != nil {
			log.Fatal("failed to kill process: ", err)
		}
		log.Println("process killed as timeout reached")
	case err := <-done:
		if err != nil {
			log.Fatalf("process finished with error = %v", err)
		}
		log.Print("process finished successfully")
	}
