如何让 cygwin .xinitrc 等待 X 服务器退出？
我正在使用 Cygwin 的 startx，并且想要自定义我的 xinitrc，这样我就不会在屏幕上看到任何“神奇”的 X 程序，即，如果我退出它们，这些程序将导致 X 服务器终止。实际上，我根本不希望任何 X 程序在屏幕上启动；我只想使用从我的 .XWinrc 自定义的 XWin 菜单。
通常，在 .xinitrc 中，我会让最后一行运行窗口管理器。然后我可以通过从窗口管理器自己提供的界面退出来退出 X。
在这种情况下，虽然我的窗口管理器和我的服务器实际上是相同的进程，因为我使用的是 XWin 服务器。我没有要执行的窗口管理器。我从 .xserverrc 文件启动服务器：
exec XWin -multiwindow -clipboard -silent-dup-error
我可以在 .xinitrc 末尾循环睡眠：
while [ 1 -eq 1 ]
do
sleep 10
done
但这似乎不太优雅。
我可以等待子进程，可以通过将其作为 .xinitrc 中的最后一行启动，或者通过在后台较早启动它并使用“wait {PID}”显式等待它。但我等不及XWin.exe进程了，因为它是我的.xinitrc脚本的父进程，而不是子进程。
我无法在 .xinitrc 末尾启动 XWin.exe；如果我尝试，我会得到一个不同的窗口管理器，显然会启动，而 XWin 不处于无根模式，然后我会立即关闭。
有没有比循环睡眠更优雅的方法呢？有没有办法从我的 .xinitrc 启动 XWin 并等待它？有没有办法告诉 .xinitrc shell 脚本只是等待而不退出，而不休眠，这样它将继续执行并且什么也不做，直到 XWin.exe 退出？我是否应该在后台启动一些东西作为 .xinitrc 的最后一行，以便给我一个等待进程而不启动 X 程序？
I'm using Cygwin's startx and want to customize my xinitrc so that I don't get any "magic" X programs on screen, i.e., programs that will cause the X server to terminate if I exit them. I don't want any X programs to start up on screen at all, actually; I just want to use the XWin menu, customized from my .XWinrc .
Ordinarily from a .xinitrc, I would make the last line run the window manager. Then I can exit X by exiting the window manager from its own provided interface.
In this case, though my window manager and my server are effectively the same process, because I am using the XWin server. I don't have a windows manager to execute. I am starting the server from my .xserverrc file:
exec XWin -multiwindow -clipboard -silent-dup-error
I can sleep at the end of my .xinitrc, in a loop:
while [ 1 -eq 1 ]
do
sleep 10
done
But that seems inelegant.
I can wait for a child process, either by starting it up as the last line in my .xinitrc, or by starting it up earlier in the background and waiting for it explicitly with "wait {PID}". But I can't wait for the XWin.exe process, because it is a parent process of my .xinitrc script, not a child process.
I can't start up XWin.exe at the end of .xinitrc; if I try, I get a different window manager apparently starting up, with XWin not in rootless mode, and then I get an immediate shutdown.
Is there a more elegant way to do this than sleeping in a loop? Is there a way to start XWin from my .xinitrc and wait on it? Is there a way to tell the .xinitrc shell script to simply wait and not exit, without sleeping, such that it will continue executing and do nothing until XWin.exe exits? Is there something I should be starting in the background as the last line of my .xinitrc, so as to give me a process to wait on without starting up an X program?

因此，总结一下 Ben Bullock 的回答，即“如何让 .xinitrc 执行此操作？”的答案。是“不要！”永远不要问“我如何使用 X 来做 Y？”问题。 :) 完全跳过 startx/.xinitrc 。
So, summarizing from Ben Bullock's answer, the answer to "How do I make .xinitrc do this?" is "Don't!" Never ask "How do I use X to do Y?" questions. :) Skip startx/.xinitrc entirely.
