[gentoo-user] Screen and Window Titles in screen

I am trying to get screen set up and am running into some issues getting
it to display titles like I want.  When I'm not running screen, commands
like emerge change the title of the console I'm currently in (like
Konsole or PuTTY (win)).  When I start up screen, all I get is the name
of the host that I am ssh'd into.  I am testing only with PuTTY right
now since I don't have access to a Linux box with X on it right now.

I figured that it might be easier to get screen to set the title of one
of the screens automatically from the title that the bash session that
it is hosting has.  After digging a bit, I found shelltitle, but that
only seems to read the name of the currently executing command, and also
overwrites the name that I might have assigned to that screen.

My goal is to have titles that are something like:
	[screen title]: [xterm title]
where I can set [screen title] using C-a A and [xterm title] is what I
would normally see as the title of an XTerm/Konsole/PuTTY.

Is it possible to achieve something even close to this?

Thanks,
Chris Lieb

PS. Where can I find a reference for the syntax for the format strings
for things like hardstatus?  I can't seem to find anything using Google.

I use PuTTY and screen and window titles are shown in the screens
during emerging, etc... I don't think I've had to do anything to
accomplish this, I'm just using the default /etc/screenrc

I did find a great status-bar that shows open screens (gentoo weekly
newsletter? or maybe on this list... don't remember):

caption always "%{= kw}%-w%{= BW}%n %t%{-}%+w %-= @%H - %LD %d %LM - %c"

As far as the syntax of the hardstatus I think it may be usual termcap syntax.

My problem was that I used hardstatus instead of caption.  This allows
the window title to be set by the terminal.

Is there a way to have a child screen session set the title of the
terminal, eg. I run emerge inside a screen inside a screen (like sshing
from one computer to another)?

Also, is there a way to get the screen title to match the terminal title?

Can you give me a pointer to where a definition of that syntax is?  All
I find is for defining capabilities of terminals.

I've never personally used it (I don't speak termcap :) ) but the
screen manual has a whole section about termcap stuff:

I'm guessing that the format for caption and hardstatus isn't termcap.

You're right; I got confused by all of the hardstatus-related termcap
commands in screenrc.
