[Linux 常見問題] How to assign name for a screen?

Source From Here
Question
I'm using the screen multiplexer tool on the command shell and open a lot of screens. I then forget which process ID associates with which task. I would like to set a name for a screen but can't find an option in the manpage.

Currently, listing the screens looks like this:

view plaincopy to clipboardprint?

1. There are screens on:  
2.     5422.pts-1.aws1 (Detached)  
3.     5448.pts-1.aws1 (Detached)  
4.     5027.pts-1.aws1 (Detached)  
5. 3 Sockets in /var/run/screen/S-sb.  

And I would like to see something like this:

view plaincopy to clipboardprint?

1. There are screens on:  
2.     5422.logCleanWorker (Detached)  
3.     5448.overNightLongTask(Detached)  
4.     5027.databaseOverNightLongTask (Detached)  
5. 3 Sockets in /var/run/screen/S-sb.  

How can I do this?

How-To
To create a new screen with the name foo, use

// -S sessionname: When creating a new session, this option can be used to specify a meaningful name for the session.
# screen -S foo

Then to reattach it, run

// -r sessionowner/[pid.tty.host]: resumes a detached screen session.
# screen -r foo # or use -x, as in
# screen -x foo # for "Multi display mode" (see the man page)
