screen技巧之重命名

创建时取名

首先来说一下创建时取名的两种方法：

screen -S my_screen_name #创建新的会话，并取名
screen -R my_screen_name #如果已经有my_screen_name，则进入这个会话，如果没有则创建一个新的会话

当然创建时取名是最好的，但是有时候我们忘记取名了也可以用下面的方法。

Summary

C-a :sessionname mySessionName

Details

第一种方法是进入会话中操作

This is,

1. Attach to the session in question.

2. Press Ctrl+A.

3. Type :sessionname mySessionName – yes, the first colon is needed there, no extra spaces.

4. Type Enter.

Example

$ screen -S foo
[detached from 8890.foo]
$ screen -ls
There is a screen on:
    8890.foo    (22/12/11 18:39:22) (Detached)
1 Socket in /var/run/screen/S-user.

$ screen -r

Ctrl+A:sessionname bars

[detached from 8890.bars]
$ screen -ls
There is a screen on:
    8890.bars   (22/12/11 18:39:21) (Detached)
1 Socket in /var/run/screen/S-user.

$ 

Renaming without attaching

第二种方法是在会话外进行操作。

Screen's -X switch lets you rename a session without attaching it.

$ screen -X sessionname foobars
$ screen -ls
There is a screen on:
    8890.foobars    (22/12/11 18:39:22) (Detached)
1 Socket in /var/run/screen/S-user.

$ 

Alternatively, you can specifically target a screen session by its existing name or id (useful if there are already multiple sessions):

$ screen -ls
There is a screen on:
    8890.foo        (02/23/2015 18:39:22)   (Detached)
    5136.barfoos    (02/23/2015 18:39:22)   (Detached)
1 Socket in /var/run/screen/S-user.

$ screen -S 8890.foo -X sessionname foobars
$ screen -ls
There is a screen on:
    8890.foobars    (02/23/2015 18:39:22)   (Detached)
    5136.barfoos    (02/23/2015 18:39:22)   (Detached)
1 Socket in /var/run/screen/S-user.
