typical user case,

I use command `only` (C-a Q) to maximize the window to observer some
log,  then I want to restore the previous layout to do other things.

Great ideal, I think I'd use that too. The following will make C-a Q toggle between the maximized window and the previous layout.

First, add these lines to your .screenrc:

layout autosave on
layout save 0
layout new ONLY
layout select 0
bind Q exec screen-ONLY

Then put this script somewhere in your PATH and call it screen-ONLY:


screen -X msgwait 0

# get the current layout name
screen -X layout show
layout=$(screen -Q lastmsg | sed 's/.*\([0-9]\+\)\*\s\+\(\S\+\).*/\2/')
if [ "$layout" == "ONLY" ]; then
    screen -X layout prev

# if layout != ONLY
# put the current window into the "ONLY" layout
window=$(screen -Q windows | sed 's/.*\([0-9]\+\)\*\s\+\(\S\+\).*/\1/')
screen -X layout select ONLY
screen -X select $window

# Return msgwait to something useful
screen -X msgwait 3
