[ This can be considered step 2 of my previous question
Is it possible to change GNU screen session
name after created? ]
Actually, I'd like to write a script that can display current screen session
name and change current session
name.
For example:
sren armcross
It will change the session
name to armcross (ARM gcc cross compiler) and output something like:
screen session
name changed from '25278.pts-15.linux-ic37' to 'armcross'
So, the key question now
is how to get current session
name. Not only for display the old session
name, but according to
Is it possible to change GNU screen session
name after created? , I have to know it(pass to -d -r) before I can change it to something else.
Can we use $STY for current session name? No. $STY will not change after you have changed the session
name to a user-defined one. However, for command
screen -d -r <oldsessname> -X sessionname armcross
should be the user-defined name(if ever defined) instead of $STY, otherwise, screen spouts error "No screen session found."
Maybe, there is a verbose way, use screen -list to list all sessions(user-defined name listed), then, match the pid part from $STY against those listed sessions and we will find current session's user-defined name. It should not be so verbose for such a straightforward question. Don't you think so?
The -d -D and -r -R options seems to expose too much implementation detail to screen's user. It seems, to rename a session, you have to detach it, then do the rename, then reattach it. Right?
My env: opensuse 11.3, GNU screen 4.00.03 (FAU) 23-Oct-06
Thank you.
