有时我的脚本会出错,并且会创建多个同名的屏幕会话。有没有一种方法可以在一个命令中杀死所有具有该名称的文件?
Rx:/scripts# screen -S haydoz-script -X quit
There are several suitable screens on:
13372.haydoz-script (09/10/11 07:44:05) (Detached)
12287.haydoz-script (09/10/11 07:30:45) (Detached)
12230.haydoz-script (09/10/11 07:17:42) (Detached)
7824.haydoz-script (09/09/11 11:42:26) (Detached)
7764.haydoz-script (09/09/11 11:35:40) (Detached)
15753.haydoz-script (09/04/11 15:00:27) (Detached)
15744.haydoz-script (09/04/11 15:00:26) (Detached)
除了这些屏幕之外,还有其他屏幕正在运行,但我不想杀死它们。
答案1
如果没有其他screen
会话正在运行,您可以使用“硬”方式,只kill
使用killall screen
.
如果你想变得友善,你可以迭代你的屏幕会话列表并一个接一个地杀死它们:
# screen -S foo && screen -S foo
[detached]
[detached]
# screen -ls
There are screens on:
8350.foo (Detached)
8292.foo (Detached)
2 Sockets in /tmp/screens/S-joschi.
# This is the interesting line. Just replace "foo" with the name of your session(s)
# for session in $(screen -ls | grep -o '[0-9]*\.foo'); do screen -S "${session}" -X quit; done
# screen -ls
No Sockets found in /tmp/screens/S-joschi.
答案2
screen -ls "$SESSION_NAME"
在制表符缩进行上列出匹配会话的全名。因此,您可以迭代这些行,提取全名,并对quit
每个匹配的名称调用命令。
SESSION_NAME='haydoz-script'
screen -ls "$SESSION_NAME" | (
IFS=$(printf '\t');
sed "s/^$IFS//" |
while read -r name stuff; do
screen -S "$name" -X quit
done
)
答案3
这是一行。您需要更换your_session
为所需的。
screen -ls your_session | grep -E '\s+[0-9]+\.' | awk -F ' ' '{print $1}' | while read s; do screen -XS $s quit; done
答案4
附加到屏幕,然后运行另一个屏幕命令:
screen -x "Name" -x -X kill
