(转) Golang非阻塞获取命令行按键

一般获取命令行按键是阻塞工的，之前使用github.com/eiannone/keyboard库，远程获取键盘没问题，但本地居然不行。

package main

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

func main() {
    ch := make(chan string)
    go func(ch chan string) {
        // disable input buffering
        exec.Command("stty", "-F", "/dev/tty", "cbreak", "min", "1").Run()
        // do not display entered characters on the screen
        exec.Command("stty", "-F", "/dev/tty", "-echo").Run()
        var b []byte = make([]byte, 1)
        for {
            os.Stdin.Read(b)
            ch <- string(b)
        }
    }(ch)

    for {
        select {
            case stdin, _ := <-ch:
                fmt.Println("Keys pressed:", stdin)
            default:
                fmt.Println("Working..")
        }
        time.Sleep(time.Millisecond * 100)
    }
}
