screen常用命令总结(支持关闭xshell窗口操作)

71824.pts-0.localhost    --> id.sessionName
screen -S dcx            --> 新建一个叫dcx的session，并登录dcx session
screen -ls               --> 列出当前所有的session以及当前状态
---------------------------------------------------
screen -d dcx            --> dcx session离线(离开dcx session)
screen -r dcx            --> dcx session恢复(退出dcx session)
Exp:
[root@localhost ~]# screen -ls
  There is a screen on:
          71331.dcx       (Detached)  --> Detached，处于离线状态
  1 Socket in /run/screen/S-root.
  [root@localhost ~]# screen -r dcx   --> 恢复dcx session
  [root@localhost ~]# screen -ls
  There is a screen on:
          71331.dcx       (Attached)  --> Attached，处于登录状态
  1 Socket in /run/screen/S-root.
  [root@localhost ~]# screen -d dcx   --> 退出dcx session
  [root@localhost ~]# screen -ls
  There is a screen on:
          71331.dcx       (Detached)  --> Detached，再次退出到离线状态
  1 Socket in /run/screen/S-root.
  
  【Note】：可以通过screen -ls通过查看Attached/Detached来判断当前用户所处状态
    [root@localhost ~]# screen -ls
    There are screens on:
            73867.xy        (Detached)
            71331.dcx       (Attached) --> 当前在dcx session中
    2 Sockets in /run/screen/S-root.
    [root@localhost ~]# screen -d dcx  --> 退出dcx session
    [root@localhost ~]# screen -ls
    There are screens on:
        	73867.xy        (Detached)
        	71331.dcx       (Detached) --> 当前没有登录任何session
	2 Sockets in /run/screen/S-root.
---------------------------------------------------
screen -d -r dcx         --> 结束当前session并回到dcx这个session
ctrl+a+d                 --> 退出当前session
screen -X -S 4588 quit   --> 关闭id是4588的session
