Question

I’d like to know if someone has tried logging their gnu-screen session to a logfile (other than the default screenlog.N where N is the session number).

I tried doing the following

~$ screen -L custom_screenlog -S test_session

but screen would terminate. It’s not also in the screen manual. Tried searching Google and I can’t seem to see an answer.

Thanks.

Answer 1

My 4.0.2 version of GNU screen has no argument to -L switch. The log file is systematically named screenlog.0 and created in the current directory.
Then you may simply try:

screen -L -S test_session

Edit:
you can customize your .screenrc file, adding for instance

logfile /tmp/screenlog-%Y%m%d-%c:%s

This way log files may be stored in a predefined directory (/tmp in this example)
and may be named after logfile opening date
