Re: screen inside of screen

Eureka!  I found my foolishness.  First I tried to set the escape
character on the remote box to ^\ and when I ssh'd to that box from
inside of a screen session, I still couldn't get it to accept the escape
character.

However, if I ssh'd into the remote box from a non-screen shell, I
didn't have any problem.  So, I looked at my .bashrc again to see what
might be happening.  For some reason (hysterical blindness?  madness?),
I didn't include this piece of my .bashrc last time I posted:

if [ "$TERM" = "screen" ]; then
        /usr/bin/fortune 
else 
        if [ "$TERM" != "dumb" ]; then
                exec screen
        fi
fi

I had just included this piece:

if [ "$TERM" = "screen" -a ! "$SHOWED_SCREEN_MESSAGE" = "true" ]; then
  detached_screens=`screen -list | grep Detached`
  if [ ! -z "$detached_screens" ]; then
    echo "+---------------------------------------+"
    echo "| Detached screens are available:       |"
    echo "$detached_screens"
    echo "+---------------------------------------+"
  else
    echo "[ screen is activated ]"
  fi
  export SHOWED_SCREEN_MESSAGE="true"
fi

Well, everytime I logged onto the remote host from inside of a screen'd
shell, I was seeing "[ screen is activated ]" on the remote host and
feeling warm fuzzies.  However, screen wasn't starting because my TERM
definition was following me over to the remote box.  So, while my TERM =
screen, screen wasn't running for that session.

I feel pretty lame.  

So, I modified my .bashrc to this:

if [ "$STARTED_SCREEN" = "true" ]; then
/usr/bin/fortune
else
        export STARTED_SCREEN="true"
        exec screen
fi

Thanks for all the help.  I apologize for my lack of clue on this one.
