screen: detach to avoid repeat logins

Entering:

screen -d

(detach screen), or hitting Ctrl-A then D whilst in a screen session, will detach your running screen, leaving it going in the background. This can be useful for running background jobs; it can also be useful for saving you frp, repeatedly logging into and out of machines. Start a screen session, log in to another machine, and detach the screen. Reattach the screen:

screen -r

and you'll be back connected to the ssh session, without having to type your password again.

screen: connect multiple users

When you're bugfixing, sometimes you really need to be able to see what the user who brought the problem to you is doing, and what output they're getting. You can use screen to avoid having to actually walk all the way over to their desk. Log on to the user's machine as them, then type:

screen -S debug

Then get them to type:

screen -x debug

and they'll join your screen session. Then whatever they do will be replicated on your screen (and vice versa). ('debug' is just the identifier; you can use any name you want.)

[Mar 12, 2008] Terminator - Multiple GNOME terminals in one window

Rewrite of screen in Python?

This is a project to produce an efficient way of filling a large area of screen space with terminals. This is done by splitting the window into a resizeable grid of terminals. As such, you can produce a very flexible arrangements of terminals for different tasks.

Read me

Terminator 0.8.1
by Chris Jones <[email protected]>

This is a little python script to give me lots of terminals in a single window, saving me valuable laptop screen space otherwise wasted on window decorations and not quite being able to fill the screen with terminals.

Right now it will open a single window with one terminal and it will (to some degree) mirror the settings of your default gnome-terminal profile in gconf. Eventually this will be extended and improved to offer profile selection per-terminal, configuration thereof and the ability to alter the number of terminals and save meta-profiles.

You can create more terminals by right clicking on one and choosing to split it vertically or horizontally. You can get rid of a terminal by right clicking on it and choosing Close. ctrl-shift-o and ctrl-shift-e will also effect the splitting.

ctrl-shift-n and ctrl-shift-p will shift focus to the next/previous terminal respectively, and ctrl-shift-w will close the current terminal and ctrl-shift-q the current window

It's quite shamelessly based on code in the vte-demo.py from the vte widget package, and on the gedit terminal plugin (which was fantastically useful).

vte-demo.py is not my code and is copyright its original author. While it does not contain any specific licensing information in it, the VTE package appears to be licenced under LGPL v2.

the gedit terminal plugin is part of the gedit-plugins package, which is licenced under GPL v2 or later.

I am thus licensing Terminator as GPL v2 only.

Using GNU screen's multiuser feature for remote support

The ^Amultiuser on is unnecessary, AFAIK. All that is necessary when two people are logged in as the same user is for one to start the screen session, then the other to connect to it with screen -x. #5

That is true. I've used screen -x to attach to screen sessions in multiple locations simultaneously for a number of years, and you don't need to do anything else for it to work. #6

On the other hand, multiuser mode CAN be used to let two DIFFERENT users to access the same screen (so you don't have to share a login password or allow an SSH key with essentially full access to the account).

By default, this is not allowed on Debian, even if you turn multiuser mode on, but if you absolutely need this functionality, you can do it this way (I just tested it---I, of course, don't use it this way):

Re binding ctrl-arrow

# a similar message was posted some time ago but I did not see any
# answer. How can I bind the sequence ctrl+arrows (up, down, left
# right)? In particular, I would like to enter copy mode with
# ctrl-UpArrow. I tried something like
# 
# bindkey -k ^ku copy

I saw this trick somewhere: I do this by firing up cat to figure out
what my terminal sees when I press Ctrl+Up and Ctrl+Down:

address@hidden:~$ cat >/dev/null
^[[1;5A
^[[1;5B

(Above produced by pressing Ctrl+Up, RET, Ctrl+Down.)

Then, I add those strings to my .screenrc:

bindkey ^[[1;5A prev
bindkey ^[[1;5B next

In my case, I use Ctrl+Up and Ctrl+Down to move around through my
screens.

This will only work as long as you're using a terminal that considers
those equivalent to Ctrl+Up and Ctrl+Down respectively.  I don't know
of a way to get them to work universally, so I just stick to xterm
(which is fine by me).

HTH,
