Attach to 'screen' session with creating a new screen window
提问by Alfe
I have a screen session running with several windows. I want to attach to it, create a new screen window within it and start a shell in that new window.
我有一个运行多个窗口的屏幕会话。我想附加到它，在其中创建一个新的屏幕窗口并在该新窗口中启动一个 shell。
Question: How can I do this from the command line outside the screen session?
问题：如何从 screen 会话外的命令行执行此操作？
I already tried a lot, e. g. screen -x(but it attaches to one of the existing screen windows; it does not create a new one nor does it start a new shell). Any hints are welcome.
我已经尝试了很多，例如screen -x（但它附加到现有的屏幕窗口之一；它不会创建一个新的窗口，也不会启动一个新的外壳）。欢迎任何提示。

To choose a window to join, use the -poption. Giving +will create a new one, so your command is simply:
要选择要加入的窗口，请使用该-p选项。给予+将创建一个新的，所以你的命令很简单：
screen -x session_name -p +
This is documented on the man page:
这记录在手册页上：
-p n̲u̲m̲b̲e̲r̲_o̲r̲_n̲a̲m̲e̲|̲-̲|̲=̲|̲+̲
Preselect a window. This is useful when you want to reattach to a specific windor or you want to send a command via the "-X" option to a specific window. As with screen's select commant, "-" selects the blank window. As a special case for reattach, "=" brings up the windowlist on the blank window.

I found something on the mailing list, thank you tuxuday :)
我在邮件列表上找到了一些东西，谢谢 tuxuday :)
I'm doing it now this way:
我现在这样做：
#!/bin/bash
screen -X screen -t NEWWINDOW # create new window (switches existing attached terminal)
sleep 0.1
screen -X other # switch existing attached terminal back to its old window
sleep 0.1
gnome-terminal -e 'screen -x -p NEWWINDOW' # connect to new window
I'm not sure about those sleeps, maybe they aren't necessary in all environments, but I can wait those 0.2s easily.
我不确定这些睡眠，也许它们在所有环境中都不是必需的，但我可以轻松地等待 0.2 秒。
My .bash_aliasesis changing the screen window title with a delay, so the awkward NEWWINDOWwon't stick for long (and thus not hinder further calls to this script).
我.bash_aliases正在延迟更改屏幕窗口标题，因此尴尬NEWWINDOW不会持续很长时间（因此不会妨碍对该脚本的进一步调用）。
