列出可用的会话

[supersun@supersun.biz ~]$ screen -ls

There is a screen on:

        763.pts-31.supersun.biz        (Attached)

1 Socket in /tmp/uscreens/S-supersun.

可以使用-r恢复指定会话,在此发现有两个会话死掉了：

[supersun@supersun.biz status]$ screen -r

There are screens on:

        19875.pts-7.supersun.biz       (Dead ???)

        3964.pts-15.supersun.biz       (Dead ???)

Remove dead screens with 'screen -wipe'.

There is no screen to be resumed.

删除死掉的会话：

[supersun@supersun.biz status]$ screen -wipe 3964.pts-15.supersun.biz

There is a screen on:

        3964.pts-15.supersun.biz       (Removed)

1 socket wiped out.

No Sockets found in /tmp/uscreens/S-supersun.

 

断开ssh客户端时，一个screen会话还没有被screen释放：

[supersun@supersun.biz ~]$ screen -r

There is a screen on:

        12381.pts-6.supersun.biz       (Attached)

There is no screen to be resumed.

找到那个进程，kill掉：

[supersun@supersun.biz ~]$ ps aux |grep screen

supersun   6416  0.0  0.0  2708  848 pts/2    S+   21:11   0:00 screen -r

supersun  10426  0.0  0.0  2060  516 pts/5    S+   21:15   0:00 grep screen

[supersun@supersun.biz ~]$ kill -9 6416

 

[supersun@supersun.biz ~]$ screen -r 12381.pts-6.supersun.biz

 

当你现在现要离开，而不想结束当前的会话的时候，只要关闭ssh客户端就行，不要使用exit。
