[screen-devel] [bug #44243] Robust Session Restoration

[Curtis Brown]

Follow-up Comment #3, bug #44243 (project screen):

The user manual at [0] is not up to date. Grab one from the newest source
package. It'll be in screen-4.2.1/doc/screen.texinfo .

I wrote those descriptions and I'm fairly certain I did a poor job of it
(suggestions are welcome). They do have to do with splits. A layout tracks how
you organize your splits and restores them when you detach and re-attach
GNUScreen or even start a fresh GNUScreen.

But I kinda agree with mikegerwitz's point of view. What may be confusing is
the overloaded use of 'session'. A screen session will let you detach a shell
from one terminal and reattach it to a different terminal. But if the
underlying shell session dies because because of a reboot, that shell and its
environment can't be recreated. For that kind of functionality, it sounds like
you need something that will capture and act on a SIGTERM that gets sent on a
shutdown. So when onSIGTERM() foreach (process) do { getCWD >
~/archeology_record.txt} or something along those lines.

You can do labeling inside GNUScreen. See the commands for :title ,
:windowlist , and :layout title. You can use :hardstatus for a persistant view
of your windows. For dynamic titling, see [1]. Put all of this customization
into your ~/.screenrc

Your .screenrc can also help in automation. One example is at [2]. Take
advantage of the (confusingly called) :screen command and :at command, and
also look at the -X commandline option
