Re: [PATCH] Document how to tell git to not launch a pager
Hello Linus,
I personally use screen a lot. I have a few screen sessions running:
- a main screen carring 70 windows. Where I do my daily work and
read my mail on. I recompiled screen to support more than 40
winodws. This screen session runs on a well connected machine.
And consumes 175M resistent memory and 450M virtual memory.
That's mainly because I have 5000 lines of scrollback buffer
in each window and I had to recompile screen with all it's
buffers 2x to fight a symtom that it always crashed for me
when I resized it to fullscreen on a monitor with resolution
of 1600x1200. Yes I did fight symptoms some times even if I
don't like it. But had you ever a look at the screen source
code. It does make you puke.
- a local screen. If I do something on a local machine I don't
open a single terminal I open a screen session with 5 windows.
Even if I only need a single shell. The local screen only
stays open as long as I am logged in. I switch machines often.
I have a workstation at home, one at university, a laptop and
one at work.
- a console screen (I do a lot of system administration) so the
serial consoles of the main servers at university are
connected to a screen session. Often are up to 5 people are
connected to that session. When you have to do some sort of
maintance work we often do a telephone conference while
everyone sees what is going on.
- a so called development screen. As you can imagine having 70
windows open you do a lot of context switches and as you
stated before "do one thing and do it well" does not work that
way when there is you mailreader in the way on window 6, so
when I do something I have to focus on I use the development
screen. For short projects I use the development screen.
- one screen for work related stuff.

so true, as I stated above. When I notice that I go sideways I use one screen per topic.

Why I started to use screen is because I often switch workstations. And I want to be able to go on where I left of. So I have the same environment on every machine I have access to and synchronize this environment. I use fvwm as window manager and have something configured I call SmartStart. This is a fvwm function which focus an application if it is already running and start it if it is not running.
Ctrl Shift s => Main Screen
Ctrl Shift l => Local Screen
Ctrl Shift o => Opera
...
(thinkpad) [~] grep SmartStart .fvwm2rc | wc -l
32

I actually have a macro for university that allows me to start X application out of my screen session but most of the time I use local X applications or use ssh forwarding if I have to get it from a remote machine.

yes you can, but you get used to it.

My main screen is running in its own ssh-agent session. So does my work screen. My local has automatically the ssh-agent session from my desktop session.

Well, I have to aggreee with you. Sometimes I come back to a windows where I stopped in the middle of doing something. And that is bad. However screen makes me work faster and makes it possible to switch locations often and pick up where you left of. It's biggest strength it's it biggest weakness, too.
My screen configuration have dozens of people copied. I have this fancy sticky status bar on the bottom.
