Re: New release
Carsten Mattner carstenmatt...@gmail.com 2012-07-21 14:52: I've been using screen for many years and it has been almost 4 years since the last official release. Are there any plans for a new release? Or should I just use screen from the master branch to get a recent version? I completely agree with the sentiment. I think it's (perhaps artificially) holding up inclusion in the major linux distros of a modern screen, which really has some nice new features to offer. Debian's experimental branch at least has a git based package now, adapted from a recent fedora package, which, from a quick glance, is the only major distro out there to have one.

Ubuntu will likely adopt the package from Debian, but maybe not for their upcoming 12.10 release anymore. Thanks to Julien Cristau there is now a patch for the 4.0.3 interoperability issue: http://anonscm.debian.org/gitweb/?p=collab-maint/screen.git;a=commitdiff;h=8700b331b4071c8158be4d6891cb7909859165a9 It looks fine after some initial testing and I'll soon upload a package to Debian Unstable including this patch. The package will likely make it in the next Debian Stable release. While testing that patch, I though noticed a few unexpected things with regards to locking screen which also happen without the patch. More details later though as I'm currently busy with other things. That's great news! The upgrade interoperability issue was holding me up from pushing that everywhere as well. I will definitely test that out later in August once I have a chance. We have hundreds of machines that we use screen on, so for ease of maintenance purposes we tend to roll with whatever the distro has in their package system, rather than either trying to maintain our own package or keeping a git copy around everywhere. For me, that's the main reason in wanting a stable release. I know at least some, if not many, others are in a similar boat. So yes, in that sense, it is a little like the OS X issue someone described earlier.

Re: Beginner Question: Is GNU Screen still in active development? Will there be future releases?
Andrew Schulman and...@alumni.utexas.net 2011-10-13 09:46: Regarding the subject, just wanted to know this because I am trying to decide whether to go with Screen or Tmux. So far in my experience, Screen seems more mature (but I might not be qualified enough to say this :-) ) . I admit a release has been slow in coming, and because of that I have also been considering a switch to tmux for a handful of features I've been waiting for. However, screen is mature and I know it well and haven't had enough time to switch yet. I also don't know if I could get tmux for some of the Solaris machines I have to deal with. Also, most of the features I wanted have been in the git version of screen for a while so development on screen does continue to progress albeit slowly. In an effort to move things along some of us have started work to try and package a git version for distros like Debian: http://noone.org/blog/English/Computer/Debian/Git%20Snapshot%20of%20GNU%20Screen%20in%20Debian%20Experimental.html http://packages.debian.org/experimental/screen I'm using it (backported for squeeze) on a large lab setup already.

I would also like to get rid of those tabs, so is there a way to somehow group the terminal sessions to specific screen domains and not leave screen but switch to the other group? What about nested screens? Also, there was a feature called window-groups in one of the development releases (I believe it's also been included in the Ubuntu/Debian packages). I can't seem to find any docs on it now though other than the list archives.

You can enter the scrollback mode with Ctrl-a-Esc or Ctrl-a-[. There you can move around with the usual navigation keys. Great. Just tried it out. This is very useful to me. Thanks. Also one more doubt I have is how I can attach to two screens together. For example, if I was working on a screen and my friend comes and start his own screen, next time when I login how can I attach both these screens together. I hope my questions are clear. I don't think you can merge running screen sessions, but you can list active sessions by 'screen -ls', and then start each session with 'screen -r nameofsession'. You could also attach each of your relevant sessions under a parent session (eg: nested screens) which could give a somewhat shoddy illusion of merging them. Is this present in the TODO list for the future versions of screen or is this something very trivial and not necessary? I have also wondered about that in the past. I typically make a screen session for one particular purpose, but later find myself adding windows to others for straying purposes. It would be cool to move those around to reorganize them. At the very least I know I can rename sessions. Having lurked on this list for a while now, I can almost hear the devs now saying, you should use the window group feature to (re)organize your windows within a single session. As soon as a new release happens I'll probably do that. I haven't yet had time to maintain my own package for all of the systems I manage to try that out :( Vignesh, perhaps that, combined with a multiuser screen session with ACLs is an option for you.

Re: How to set screenname automatically to hostname.
I'm sure I've made this comment before, but this thing is worth looking
at if you're using bash, else zsh natively has the ability to do it.
Basically it allows you to run a command just before every command you
run whereas the PROMPT_COMMAND gets run just before it prints a new
prompt (ie: after you've run the command).
http://www.twistedmatrix.com/users/glyph/preexec.bash.txt
http://glyf.livejournal.com/63106.html?thread=210818
I've used some variant of this for a long time and am quite happy with
it. With it and some other environment variables in place on the
machines you're using (easier if you've got shared remote home dirs of
some sort) you can have the screen title set to whatever long running
program you last executed on the host in question and include some other
information like what machine you're on as which user and what directory
you're in.
The exact output can be customized, but here's an example window list:
1 @tux-63:~ $ vim foo.txt
2 ~ $ vim bar.txt
3 r...@tux-64:/tmp #
4 ~ $ ssh somehost
1) Is my user on a different machine running vim of some file.
2) Is my user on the local machine running vim of another file.
3) Is a bash session in /tmp as root on a different machine.
4) Would be an ssh session to some host that doesn't have your
bash.preexec setup on it. Basically the title stays the same until the
command finishes so it would still be possible to identify the host
you're ssh'd to, though in this case it would only go one level deep
whereas having things setup everywhere means it will always reset your
window title no matter how many machines you ssh through.
As another example here's my current caption line:
1$ ~ $ mutt 2-!$ ~ $ irssi ...
Now if only I could search the window list on the title :)
Cheers,
Brian

Is it possible to use the Windows key (Super_L) (between Ctrl and Alt) as the screen escape key? If so, how do you set this in your .screenrc? I'll take a stab at this. Assuming you're running Linux, there are two cases to consider: ... 2. Running a virtual terminal from X (such as xterm or rxvt) I think it is not possible in this case because the terminal never sees the keycode Super_L generates. It is usually intercepted by your window manager before being passed to an application. However, you might be able to hack your X keyboard map to re-map Super_L into something that would be passed onto your application by your window manager. But, that may also cause Super_L to lose its super meaning for any other apps that may wish to use it. Actually, using urxvt (and possibly xterm) you can have it interpret various keys (and buttons) as arbitrary escape sequences or keys. You might be right that the desktop environment may get in the way. I'm personally using fluxbox because I like to have lots of control over my key bindings, but something like gnome might gobble them up depending upon how they are mapped (eg: .Xmodmap or other keyboard shortcuts). Though not entirely related to the original question, here's a set of info that I just recently cooked up that shows how to bind the mouse buttons to escape sequences for the purposes of getting mouse scrolling to work inside various console apps that may or may not support it directly like less, vim, mutt, irssi, screen, any of these inside screen, etc. The principals for binding other keys should be basically the same. http://homepages.cae.wisc.edu/~bpkroth/src/terminal-mouse-scrolling/README http://homepages.cae.wisc.edu/~bpkroth/src/terminal-mouse-scrolling.tar.bz2 Cheers, Brian ... ___ screen-users mailing list screen-users@gnu.org http://lists.gnu.org/mailman/listinfo/screen-users

what the %-48= bit is about.
Here's the .screenrc section:
# This adds a statusbar:

truncated with ...
# - the active window and it's flags are in bold cyan and aligned slightly to
the left
# - the rest of the windows are printed and truncated so that

I'm assuming you want it to change back automatically when you close the ssh connection. There's some documentation in man screen about dynamic window titles that are based off of your shell prompt. Search for TITLES. If you're using bash, I've also had good luck with this script: http://www.twistedmatrix.com/users/glyph/preexec.bash.txt It emulates a feature in zsh called preexec, where you can configure a command to run just before the shell execs your input. This is different from precmd (bash's PROMPT_COMMAND), which only executes just before the shell prints the prompt (ie: after your input returns). Then, include this in your .screenrc # Export a variable denoting the original host screen was started on. # This is used by the bash.preexec stuff: # http://glyf.livejournal.com/63106.html?thread=210818 setenv SCREEN_RUN_HOST $SCREEN_HOST setenv SCREEN_RUN_USER $USER setenv LC_SCREEN_RUN_HOST $SCREEN_HOST setenv LC_SCREEN_RUN_USER $USER The bash.preexec script can make use of these variables to change your prompt based on the machine you're connected to and where the screen session is running. It also depends on SendEnv LC_* in your .ssh/config and AcceptEnv LC_* in the remote sshd_config. I think Debian has that by default. I've done much more fiddling with the original to make it display how I like it, but the hard work has been done for you already.
