screen logging
((ctrl-a) H)
sometimes it’s important to keep track of what I do to some servers. this is very easy with screen.
((ctrl-a) H) creates an ongoing logging of the session.
screen will start capature through multiple sessions.
very useful for capturing what you have done…
manpage says: Begins/ends logging of the current window to the file “screenlog.n”
You can also use ‘screen -L …‘ when starting screen to activate session logging.
~/.screenrc
# Enable mouse scrolling and scroll bar history scrolling
# This will enable scrolling in terminal, but you will
# only be able to see output of running commands since you
# connected to screen and scroll using your mouse wheel.
# To see earlier output of running commands, you can still
# use the ((ctrl-a)esc) shortcut in screen sessions.
