Screen help

[Tony Baechler]

Hi all,

I know some of you here use the "screen" package.  I'm having a slight 
annoyance and I'm wondering what I'm doing wrong.  First, I don't like tmux 
because it seems to use more memory and shows an annoying clock which seems 
to interfere with console output.  It reads the time when the clock is 
updated and makes it hard to review what's on the screen.  I'm sure there is 
a way around this, but Screen is older and more established, so that's what 
I use here.

What I want to do is always have Screen start when I log into a shell.  It 
doesn't need to start for subshells since I can create new windows as 
needed.  If I already have a detached session, I would like it to reattach 
automatically.  I added a line to /etc/bash_profile so it would start for 
all users which is what I want.  The problem is that it always launches a 
new shell when I log in, so I have to log out twice.  I first press ^D which 
ends the Screen session and ^D again to actually close my ssh connection. 
Is there a way that I don't have to do this?  I could make screen my shell, 
but I don't know if that's a good idea.  What do other people do?  I read 
the man page and I don't see a way to get Screen to become the parent shell 
without launching a new shell when it starts.

Thanks for any ideas and suggestions.
