Fwd: screen - bash history

To also give a screen-related answer: You can enable logging in screen.
This gives you a complete transcript file for each session in a separate
file.
That should help also to diagnose what happened right before a screen
sesison was killed, and such.
(But when there was no logging, and shell history got lost, you have very
little chance of diagnosing a crash that already happened. - Maybe some
sudo or ssh commands leave traces in the syslog, but most commands don't )
