I think you want to add the /c
switch to cmd.exe:
output, err := exec.Command("cmd", "/c", "node -v").CombinedOutput()

cmd := "node -v"
output, _ := exec.Command("bash", "-c", cmd).Output()
And you can put long, even multi-command commands in cmd, e.g
cmd := fmt.Sprintf("cd %s; tar czf %s.tgz *.log; tar tvf %s.tgz", path, taskId, taskId)
