Terminal

  • 电传打字机 (Teletypewriter, TTY) 是物理设备, 最初是为电报设计, 后来被连接到计算机上, 发送输入和获取输出.
  • 电传打字机 (TTY) 现在被运行在内核中的模块所模拟, 被称为终端模拟器 (Terminal Emulator).
  • 伪终端 (Pseudo Terminal, PTY) 是运行在用户区的终端模拟程序.
  • Shell 由 Terminal fork 出来, 是 Terminal 的子进程. Terminal 处理键盘事件, 负责字符的显示. Shell 负责解释执行用户输入的字符, 返回操作系统底层响应.
  • 可以使用 stty 命令对 TTY 设备进行配置.
  • 远程终端 ssh 也是一种伪终端 PTY:
    • Local: PTY Master is Terminal, PTY Slave is bash and ssh client.
    • Remote: PTY Master is ssh server, PTY Slave is bash.
