How to stop a screen process in linux?

CTRL+a and then 'k' will kill a screen session.
CTRL+a 然后 'k' 将终止屏幕会话。

There are a couple of 'screen' ways to kill a specific screen session from the command line (non-interactively).
有几种“屏幕”方法可以从命令行（非交互式）终止特定的屏幕会话。
1) send a 'quit' command:
1）发送“退出”命令：
screen -X -S "sessionname" quit
2) send a Ctrl-C to a screen session running a script:
2) 将 Ctrl-C 发送到运行脚本的屏幕会话：
screen -X -S "sessionname" stuff "^C"
In both cases, you would need to use 'screen -ls' to find the session name of the screen session you want to kill ... if there is only one screen session running, you won't need to specify the -S "sessionname" parameter.
在这两种情况下，您都需要使用 'screen -ls' 来查找要终止的 screen 会话的会话名称...如果只有一个 screen 会话正在运行，则不需要指定 -S “会话名称”参数。

I used this to quit hundreds of erroneous screen sessions created by a buggy command:
我用它来退出由错误命令创建的数百个错误的屏幕会话：
for s in $(screen -ls|grep -o -P "1\d+.tty"); do screen -X -S $s quit; done;
for s in $(screen -ls|grep -o -P "1\d+.tty"); do screen -X -S $s quit; done;
where: the grep -o -P "1\d+.tty"is the command to get session names with Perl-like name regex "1\d+.tty"which captures all sessions start with number 1, has some other numbers (\d) and end with .tty
其中：grep -o -P "1\d+.tty"是使用类似 Perl 的名称正则表达式获取会话名称的命令，"1\d+.tty"它捕获所有以 number 开头的会话1，还有一些其他数字 ( \d) 并以.tty
Warning: You should test with this command first to see you get the exact list of sessions you want before apply the above command. This is to avoid quitting unwanted sessions:
警告：在应用上述命令之前，您应该首先使用此命令进行测试，以查看您获得所需会话的确切列表。这是为了避免退出不需要的会话：
for s in $(screen -ls|grep -o -P "1\d+.tty"); do echo $s; done;
for s in $(screen -ls|grep -o -P "1\d+.tty"); do echo $s; done;
I always to this echotest whenever the list in forloop is not clear, for example, the one generated by sub-command in $()expansion.
echo每当for循环中的列表不清楚时，我总是进行此测试，例如，$()扩展中的子命令生成的列表。

previous answers didn't work for me on a winputty terminal and amazon ssh server connection.. but this one does work:
以前的答案在 winputty 终端和亚马逊 ssh 服务器连接上对我不起作用..但这个确实有效：
screen -S yourscreentitlehere -X stuff $'##代码##3'
