英文:
how to use Golang to shell command with given sudo password
问题
我可以帮你翻译这段代码。以下是翻译好的内容：
我想使用一段命令行代码在Go中设置日期时间，但是下面的代码失败了：
datetime := "2021-06-17 18:20:41.8"
sudoPassword := "xxxxx"
app := "echo"
arg0 := sudoPassword
arg1 := "|sudo -S"
arg2 := "date"
arg3 := "-s"
arg4 := "\"" + datetime + "\""
cmd := exec.Command(app, arg0, arg1, arg2, arg3, arg4)
有没有一种正确的方法来做到这一点？像在Python中那样自动填充密码：
os.system('echo %s|sudo -S %s' % (sudoPassword, command))
希望这能帮到你！
英文:
I'd like to use a piece of command line to set datetime in Go,
but the following code failed
datetime := "2021-06-17 18:20:41.8"
sudoPassword := "xxxxx"
app := "echo"
arg0 := sudoPassword
arg1 := "|sudo -S"
arg2 := "date"
arg3 := "-s"
arg4 := "\"" + datetime + "\""
cmd := exec.Command(app, arg0, arg1, arg2, arg3, arg4)
Is there a correct way to do this? Fill the password automatically like in Python
os.system('echo %s|sudo -S %s' % (sudoPassword, command))

你的代码存在一个问题，就是exec.Command直接执行命令而没有包装shell，但你构建了一个shell管道。你可以手动指定一个stdin reader来与sudo一起使用。
cmd := exec.Command("sudo", "-S", "--", "cat", "/etc/shadow")
cmd.Stdin = strings.NewReader("mysecretpassword") // 将你的密码直接传递给sudo的stdin
英文:
One issue with your code is that exec.Command execs commands directly without a wrapping shell, but you have constructed a shell pipeline. You can manually specify a stdin reader for use with sudo, though.
cmd := exec.Command("sudo", "-S", "--", "cat", "/etc/shadow")
cmd.Stdin = strings.NewReader("mysecretpassword") // your password fed directly to sudo's stdin
