杀死多个同名的 GNU 屏幕会话

Question

有时我的脚本会出错，并且会创建多个同名的屏幕会话。有没有办法在一个命令中用这个名字杀死所有这些？

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)

除了这些我不想杀死的屏幕之外，还有其他屏幕正在运行。

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.

如果你想保持友好，你可以遍历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)
