anyone familiar with "screen" here?

newbie

Hi All -

Anyone uses "screen" on Linux a lot? I have a simple question.

Is there any way to display the programs that are running on the
current screen only?
For example,
on screen 1, I use "gvim" to open files a.c and b.c;
then I start a new screen 2;
on new scrren 2, I use "gvim" to open some other files c.c and d.c.

Is there a way that when I switch to screen 1, I only see a.c and b.c
(they are both in seperate gvim windows) - I don't see c.c or d.c here;
and when I switch to screen 2, I only see c.c and b.c, not a.c or b.c.

Currently, if I start screen without any parameters, all the file a.c
b.c c.c and d.c are displayed no matter which scrren session I swtich
to. If I need to use "gvim" to open a lot of files on each screen, I
just have too many gvim windows when I have more screens. In this case,
I have to open another new SSH session when I remotely work on a
server.

Thanks for any help.

Best.

What you want is what I would expect screen to do normally. If this
isn't happening, gvim must be detecting that it's running twice within
the same screen session, and doing something special to work together.
So the issue isn't with screen, it's with gvim.

Why not use plain vim, and open each file in a new screen? Or you could
use a window manager with multiple workspaces, and make your xterm
"sticky", but I don't know if it would be possible to automatically
change to a different workspace and a different screen at the same time.

You are confused. Screen multiplexes multiple tty sessions to one tty.
This is useful for character-based applications (like plain vim), not
GUI applications (like gvim) which bypass screen to connect to your X
server.

Doh?

So basically if I use GUI applications, like gvim, screen won't do much
on them, and there is no way to tell the GUI applications to follow
screen's rules?

I use gvim whenever possible, because I have some colors configured for
gui vim, while plain vim running on a color term doesn't have them.

Thanks for everyone's input.

I'm not sure you are using screen for its intended use. Instead of
launching a graphical editor within screen maybe you just want a
terminal editor. Try launching 'vim -X' instead of 'gvim'. If you
aren't doing anything with X windows, maybe do '# unset DISPLAY' before
launching screen for the first time so that any new screen windows don't
inherit the $DISPLAY variable.

Sorry, but I can't help much further without more clarification of the
problem you are having.
