Linux 如何强制从另一个 SSH 会话中分离 Screen？

How do I force detach Screen from another SSH session?

提问by T. Brian Jones

I had Screen running inside an SSH session. Terminal froze. After restarting Terminal, that Screen session still thinks it's attached. Maybe it is. Perhaps I don't really know what that means.

我在 SSH 会话中运行 Screen。终端冻结。重新启动终端后，该 Screen 会话仍然认为它已附加。也许是。也许我真的不知道这意味着什么。

I'd like to attach to that Screen session from a fresh SSH login. I do not want to kill that Screen session as important things are happening over there. : )

我想从新的 SSH 登录附加到该 Screen 会话。我不想终止那个 Screen 会话，因为那里正在发生重要的事情。:)

The options I think I have ( none of which I know how to solve ):

我认为我拥有的选项（我都不知道如何解决）：

• How do I detach that Screen session?
• How do I kill the SSH session that that Screen session is attached to?

• 如何分离该 Screen 会话？
• 如何终止该 Screen 会话附加到的 SSH 会话？

As Jose answered, screen -d -rshould do the trick. This is a combination of two commands, as taken from the man page.

正如何塞回答的那样，screen -d -r应该可以解决问题。这是两个命令的组合，取自手册页。

screen -ddetaches the already-running screen session, and screen -rreattaches the existing session. By running screen -d -r, you force screen to detach it and then resume the session.

screen -d分离已经运行的屏幕会话，并screen -r重新附加现有的会话。通过运行screen -d -r，您可以强制 screen 分离它，然后恢复会话。

If you use the capital -D -RR, I quote the man page because it's too good to pass up.

如果您使用大写字母-D -RR，我会引用手册页，因为它太好了，不容错过。

Attach here and now. Whatever that means, just do it.

Note: It is always a good idea to check the status of your sessions by means of "screen -list".

在这里和现在附上。不管这意味着什么，就去做吧。

注意：通过“screen -list”检查会话状态总是一个好主意。

Explained answer

解释的答案

Background:When I was looking for the solution with same problem description, I have always landed on this answer. I would like to provide more sensible solution. (For example: the other attached screen has a different size and a I cannot force resize it in my terminal.)

背景：当我寻找具有相同问题描述的解决方案时，我总是落在这个答案上。我想提供更明智的解决方案。（例如：另一个附加屏幕的大小不同，我无法在我的终端中强制调整它的大小。）

Note:PREFIXis usually ^A= ctrl+a

注意：PREFIX通常是^A=ctrl+a

Note:the displaymay also be called:

• "user front-end"(in atcommand manual in screen)
• "client"(tmux vocabulary where this functionality is detach-client)
• "terminal"(as we call the window in our user interface) /depending on

注：该显示器也可以称为：

• “用户前端”（at在屏幕中的命令手册中）
• “客户端”（此功能所在的 tmux 词汇表detach-client）
• “终端”（正如我们在用户界面中所说的窗口）/取决于

1. Reattach a session: screen -x

1. 重新连接会话：screen -x

-xattach to a not detached screen session without detaching it

-x附加到未分离的屏幕会话而不分离它

2. List displaysof this session: PREFIX*

2.列出显示本次会议：PREFIX*

It is the default key binding for: PREFIX:displays. Performing it within the screen, identify the other displaywe want to disconnect (e.g. smaller size). (Your current displayis displayed in brighter color/bold when not selected).

它是以下的默认键绑定：PREFIX:displays。在屏幕内执行它，确定我们要断开连接的其他显示器（例如较小的尺寸）。（您当前的显示器在未选择时以更亮的颜色/粗体显示）。

term-type   size         user interface           window       Perms
---------- ------- ---------- ----------------- ----------     -----
 screen     240x60         you@/dev/pts/2      nb  0(zsh)        rwx
 screen      78x40         you@/dev/pts/0      nb  0(zsh)        rwx

Using arrows ↑↓, select the targeted display, press dIf nothing happens, you tried to detach your own display and screen will not detach it. If it was another one, within a second or two, the entry will disappear.

使用箭头↑↓，选择目标显示器，按d如果没有任何反应，您尝试分离自己的显示器，屏幕将不会分离它。如果是另一个，在一两秒钟内，该条目将消失。

Press ENTERto quit the listing.

按ENTER退出列表。

Optionally:in order to make the content fit your screen, reflow: PREFIXF(uppercase F)

可选：为了使内容适合您的屏幕，回流：（PREFIXF大写 F）

Excerpt from man page of screen:

摘自屏幕手册页：

displays

Shows a tabular listing of all currently connected user front-ends (displays). This is most useful for multiuser sessions. The following keys can be used in displays list:

• mouseclickMove to the selected line. Available when "mousetrack" is set to on.
• spaceRefresh the list
• dDetach that display
• DPower detach that display
• C-g, enter, or escapeExit the list

显示

显示所有当前连接的用户前端（显示）的表格列表。这对于多用户会话最有用。以下键可用于显示列表：

• mouseclick移动到选定的行。当“鼠标跟踪”设置为打开时可用。
• space刷新列表
• d拆开那个显示器
• D电源分离那个显示器
• C-g, enter, 或escape退出列表
