这是如何通过 go 中的系统调用获取 (POSIX) 终端大小的方法：

func getTermDim() (width, height int, err error) {
    var termDim [4]uint16
    if _, _, err := syscall.Syscall6(syscall.SYS_IOCTL, uintptr(0), uintptr(syscall.TIOCGWINSZ), uintptr(unsafe.Pointer(&termDim)), 0, 0, 0); err != 0 {
        return -1, -1, err
    }
    return int(termDim[1]), int(termDim[0]), nil
}

现在，同样的事情，用 os/exec 调用 stty：

func getTermDim() (width, height int, err error) {
        cmd := exec.Command("stty", "size")
        cmd.Stdin = os.Stdin
        var termDim []byte
        if termDim, err = cmd.Output(); err != nil {
                return
        }
        fmt.Sscan(string(termDim), &height, &width)
        return
} …
