如何在屏幕窗口中杀死bash文件运行的所有任务？

Question

Perhaps the answer is already out there, but after reading several Questions i didn't manage to do what I need.

My situation: I am using a machine through ssh . I created a screen window, I called a bash file like the following:

for var in 1..N
do
java -option $var
done

with N very high.

Question: Is there a way to kill the all the java tasks launched by the bash file at once? Or to kill the screen window and everything is running in the screen?

Note : The java tasks are running -inside the screen - in the foreground. If I try to do CTRL-C I can kill only one java task at the time.

Answer 1

1. Find out the process ID of the screen session.
2. Use this pid number to kill screen and all its child processes

For example:

Put screen in the background ( Ctrl-Alt + D )

List your open screen sessions:

screen -ls

You'll get something like:

There is a screen on:
    2222.pts-3.yourmachine    (Detached)

The first number is the process ID of the screen session.

Use this number to kill the screen and all its childs:

PID=2222
kill $PID

If your java application catches some signals, use a less graceful way to kill them, eg kill -9 $PID

Answer 2

如果你不害怕杀死任何正在运行的java进程你可以做总是有用的“killall -9 java”:)
