具有“恢复会话”function的终端仿真器，如Mac终端
Mac终端能够恢复以前的会话。 我刚刚重启MacBook，当终端打开时，我以前的所有命令都显示在显示屏和所有选项卡中，好像它从未关闭过。 恢复日期只有很少的通知。
是否有一个具有类似function的Ubuntu终端模拟器？
使终端会话持续存在的一个好方法是在服务器上运行“屏幕”会话。 “屏幕”会话为您提供了多个窗口，您可以在该服务器上登录其他计算机或其他任何机器。 您可以在服务器上运行多个“屏幕”会话。 您可以断开连接并重新连接到所需的会话。 ‘screen’是老式的命令行键盘，但非常值得学习和玩，以了解它是如何工作的。 维基百科很好地描述了screen “GNU Screen是一个终端多路复用器，…允许用户在单个终端窗口内访问多个单独的登录会话，…即使用户断开连接，远程进程也会继续运行。” 它有一些很大的优点：
- 易于安装，可在任何unix（或cygwin）上运行，无需图形（除了终端文本图形）
- 给出持久的窗口终端会话（只要服务器没有重启）

-
screen– 运行屏幕以简单地创建新会话 -
screen -ls– 列出正在运行的屏幕会话 -
screen -r 20229.pts-2.bangor– 重新连接到会话
*屏幕ESCAPE char默认为Ctrl-a *，除非某些疯狂的looper在.screenrc中更改了它，例如对于不重视进程后台控制的人来说，“escape ^ Zz”。 如果在屏幕上运行，要获得真正的Ctrl-a到终端（转到行首），只需Ctrl-a Ctrl-a 。
-
ESCAPE c – 创建新的屏幕窗口
-
ESCAPE 0（或1 2 3 4 5 6 7 8 9） – 切换到窗口0（或1 2 ..）
-
ESCAPE p或ESCAPE n – 切换到上一个或下一个窗口
-
ESCAPE“ – 窗口列表
-
ESCAPE h – 显示屏幕帮助：

例如，重新连接到会话：
$ screen -ls有以下屏幕：24560.pts-6.mabrowka（Detached）20229.pts-2.mabrowka（附加）2个/ var / run / screen / S-garmon中的套接字。
$ screen -r 20229.pts-2.mabrowska

对于提出的问题，这不是一个很好的答案。
但它实际上是你正在寻找的答案！ > 😉
screen非常有用。
玩得开心！
