Ga> It's a terminal multiplexer. It allows you to connect into a remote
Ga> system, open a screen session (terminal), and run something in that
Ga> terminal. You can then "detach" from that screen session, close your
Ga> SSH connection, and go on with whatever else you might be doing. Later,
Ga> you can SSH back to that machine, and "reconnect" to that open terminal
Ga> which is still running whatever you started in it.
Awesome; what I've learned so far is that I'm missing out by not using one or
the other. I know screen a little, so I guess I'll start there.. stupid, too -
its exactly what I've needed on many occasions. Derp.
Ga> Here's an example of one way that I use it. I have an Raspberry Pi
Ga> running 24x7, which does various things for me (it does not run my BBS
Ga> though). I SSH to it from my laptop (either from within the LAN, or
Ga> remotely from another state if I'm traveling). I have opened a screen
Ga> session on it, and started the 'irssi' IRC client in that terminal.
Ga> This connects and idles in the Synchronet IRC channel. I then can
Ga> detach from that session (with Ctrl-A, D), and close my SSH connection. A
Ga> few hours, or a few days later, I can SSH back to the RPi, restore my
Ga> screen session (with "screen -r"), and BAM! my irssi client is there where
Ga> I can scroll back and see what's been talked about while I was gone.
Ga> Maybe I add some comments, whatever. Then I detach and close again, and
Ga> the irssi client continues running while I'm gone. This allows me to
Ga> maintain a "presence" in that channel even if I'm not actively watching it
Ga> for a while, and I can catch up when it's
Ga> convenient for me. You can open as many screen sessions on a remote
Ga> host as you'd like, all doing something different, and all will keep on
Ga> working after you detach. Pretty cool stuff.
Yep... awesome. :P I'll be doing the same exact thing shortly. Like I can have
one Raspberry Pi that allows me access to my local network and screen around
from there. Again, I'll brush up myself but... seems like I can have a few
things 'screened' and ... I'm sure theres a way to get a list of whats open on
what screens... :P
I should have investigated this long ago - as I've used it with irssi, too, to
put the handle lists on the right hand side of the screen - but I didn't realize
that it does much more for the type of computery stuff I do all the time. :P
(I'll admit that I've used VNC to do much the same... with a lot more resources
that screen would take. Ugh.)
