Log output for screen

The one thing that annoys me when I use screen is that I can’t scroll up after a long output has printed. To log outputs, add the following near the top (required!) of your screenrc file ($HOME/.screenrc):

# auto-log http://www.cmdln.org/2007/07/20/automatic-session-logging-and-monitoring-with-gnu-screen-for-the-paranoid/
## search for "STRING ESCAPES" in the manpage
# logfile /tmp/screen_%Y-%m-%d-%c:%s_%n.log
## not using above because every window gets its own time too.  rather use session name; need 4.01.00devel (GNU450e8f3) 2-May-06 and above
logfile /tmp/screen-%S-%n.log
deflog on

For example, my rc file now looks like:

escape ^Oo
# auto-log http://www.cmdln.org/2007/07/20/automatic-session-logging-and-monitoring-with-gnu-screen-for-the-paranoid/
## search for "STRING ESCAPES" in the manpage
# logfile /tmp/screen_%Y-%m-%d-%c:%s_%n.log
## not using above because every window gets its own time too.  rather use session name; need 4.01.00devel (GNU450e8f3) 2-May-06 and above
logfile /tmp/screen-%S-%n.log
deflog on
##escape \56\56 ##ascii octal http://www.robelle.com/library/smugbook/ascii.html http://www.ncsu.edu/it/mirror/ldp/LDP/LGNET/147/appaiah.html Use C-. for escape
## following for starting screen at 1 instead of 0
## http://www.linuxquestions.org/questions/linux-software-2/gnu-screen-start-window-numbering-at-1-keep-window-number-0-from-ever-being-used-772580/
bind c screen 1
bind 0 select 10
screen 1
select 1

When I originally had the log options at the bottom, logging did not work for me.

Finally, you can use the %S string escape to refer to the session name in screen 4.01.00devel (GNU450e8f3) 2-May-06 and after. It might be wise to install the git version of screen.
