For you Linux users... what's your pick - screen or tmux, and why?

Thanks.

I got started with screen, but nowadays I use tmux more often. The main reason is that it is in OpenBSD's base install, so I just got used to it. It is also licensed under a BSD-like license, if you care about such things. In addition, its keyboard commands are a bit easier for my fingers.

In the end of the day it is just another Vim vs Emacs war.

Hi Gamgee,

For you Linux users... what's your pick - screen or tmux, and why?

I'm using screen, just because that's the command I learned first and it works just fine for the purposes I need it, which are mostly "keep a session open even if I get disconnected from my SSH session" and "use a single SSH session but run multiple shell commands in parallel".
And I got used to the basic Ctrl-A key commands :)

Regards,
Anna

and it's easier.

Okay. The commands are all customizable if desired... I've always used
screen too, but have been playing with tmux some lately. It does have
some VERY nice features, and is very configurable. I especially like
being able to have more than one "window" available (proper term might
be "session", I'm not sure). Also splitting it into multi panes is very
cool. I will probably eventually switch over to using it exclusively.

In the end of the day it is just another Vim vs Emacs war.

Hehe, I suppose that is probably true. Nano for the win. ;-)

Yeah, same here. Take a look at tmux if you get bored, it has some
pretty cool features that go a little beyond screen. I still mostly use screen too, but will likely move to tmux eventually.

And I got used to the basic Ctrl-A key commands :)

Yep. Tmux uses Ctrl-B as it's prefix by default, which is extremely
awkward, but thankfully it's easily configured to Ctrl-A. ;-)

You probably already know this, but you can "permanently" define your
desired prefix key in a config file (Linux "dotfile") called .tmux.conf

My very simple config looks like this:

# remap prefix from 'C-b' to 'C-a'
unbind C-b
set-option -g prefix C-a
bind-key C-a send-prefix

# split panes using | and -
bind | split-window -h
bind - split-window -v
unbind '"'
unbind %

# switch panes using Alt-arrow without prefix
bind -n M-Left select-pane -L
bind -n M-Right select-pane -R
bind -n M-Up select-pane -U
bind -n M-Down select-pane -D

traditionally when a process's controlling terminal closes, the programs running in it close. so yeah, like if your ssh session were to disconnect because the power went out, what you were currently doing would abruptly end. this could be particularly annoying if you were doing something like compiling firefox ;) (from remote i guess so the server still had power lol)

so now screen/tmux take the role of controlling terminal and have special handling for that event.

this probably mattered more when these machines were actually multiuser (as in actual people) and resources were scarce. there are a few public *nix machines out there that do still limit users to one process running while they're not logged in (or one + tmux).

Hey Paulie,

I do not use screen/tmux... I've used it a time or two that I needed to do something special with irssi (put handles on the left side
of screen..) but I don't understand/know what its uses ARE.

The main reason I started using it is for disconnected sessions.

I can jump into a box, do some work, disconnect, comeback later, re-connect and see what happened.

In the old modem dialup internet days (or iffy internet connections), this was a saviour.

These days, I work at my desk on an iMac, or sit in front of the TV with a MacBook - and I can "switch" to either and continue where I left off.

The other benefit, especially when developing, one window "pane" is the tail of a debug log file, while another is an interface into the DB and the 3rd where I'm watching incoming HTTP requests. I can zoom into any pane to see more content, or have all 3 on the screen at once while I'm trying to figure out why an API call is failing.

Yes.

Would you mind explaining a quick overview of what screen is? And
used for? Possibly how it help sysOps running a BBS on another
system on their network.

It's a terminal multiplexer. It allows you to connect into a remote
system, open a screen session (terminal), and run something in that
terminal. You can then "detach" from that screen session, close your
SSH connection, and go on with whatever else you might be doing. Later,
you can SSH back to that machine, and "reconnect" to that open terminal
which is still running whatever you started in it.

Here's an example of one way that I use it. I have an Raspberry Pi
running 24x7, which does various things for me (it does not run my BBS though). I SSH to it from my laptop (either from within the LAN, or
remotely from another state if I'm traveling). I have opened a screen
session on it, and started the 'irssi' IRC client in that terminal.
This connects and idles in the Synchronet IRC channel. I then can
detach from that session (with Ctrl-A, D), and close my SSH connection.
A few hours, or a few days later, I can SSH back to the RPi, restore my
screen session (with "screen -r"), and BAM! my irssi client is there
where I can scroll back and see what's been talked about while I was
gone. Maybe I add some comments, whatever. Then I detach and close
again, and the irssi client continues running while I'm gone. This
allows me to maintain a "presence" in that channel even if I'm not
actively watching it for a while, and I can catch up when it's
convenient for me. You can open as many screen sessions on a remote
host as you'd like, all doing something different, and all will keep on working after you detach. Pretty cool stuff.

Also, pls know that I'm 'man screen'ing right now... :P

Good call!

You still have to "ESC" before you can :x if you're in edit/insert mode. That's what the ctrl-[ is helpful for.. Interesingly enough, my ESC key is broken, so other than using an on-screen keyboard, I've had to figure this out lately... ;-)

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.

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.)

I have a love / hate relationship with screen. Even on the best of
days, screen breaks emulation when I go between traditional Linux-based
systems and AIX. AIX uses vt220/vt320 throughout SMIT (smitty). I've
got to the point where I don't use SMIT because the emulation keeps
getting trashed and have to remember command-line syntaxes that go
upwards of 100 characters. :|

I use picocom. It's got enough command line switches to
warrant a shell script to launch it.

Will convert line endings on the fly; supports ascii-xfr.

I use it to talk to microcontrollers via USART or USB
(CDC/ACM stuff).

I have no idea if it'll telnet or ssh.

Sometimes I'll try tinyfugue by .. I don't remember .. at
some point I'm pretty sure I need to be listening for telnet
inbound connections to use tinyfugue effectively (because it
was designed to talk to telnet destinations such as LambdaMOO).

So I probably /world localhost or similar to telnet to the
(Linux) locahost. When I get a shell prompt (split screen,
like IRSSI for example) I can then ssh out to a BBS on the
Internet.

SCREEN is great if you have a shell account on someone else's
machine, because of the detach/attach feature; it lets you
stay logged into a BBS that doesn't time out your session,
even when your modem has dropped carrier (including shutting
down a DSL modem for any reason you may want to do so).

It tmux had zmodem support, I would switch, but it doesn't. I am actually using tmux now to try it out. I actually find it useful for a quick file transfer, its a little more convienient than using SSH or netcat.

I used c-kermit under tmux for a while in order to handle XYZModem stuff for a while.
It works ok. Still it looks like the process is a bit more streamlined under screen,
or that is the memory I have from when I looked into the documentation.

For you Linux users... what's your pick - screen or tmux, and why?

Tmux - it just makes more sense to me. I'm a little late to the game, playing more with screen multiplexers now. Where I used to open a couple of Putty sessions, I can now do everything with one session and Tmux.

Honestly I think you're in a good position. I use screen because I've been around for a while and screen was the first really decent terminal
multiplexer. The codebase for GNU Screen is pretty gnarly and there's not a
lot of substantial development on it to speak of. tmux has a cleaner (and smaller/simpler) codebase and attracts more development.

I tried tmux once and it was fine. I spent all my time configuration it to
work like screen and thought "well, this is pointless, I'll just use screen".
I think if I were coming into it new and didn't have any habits and muscle-memory built up, I would start with tmux, though.

I'll use screen until I need something screen can't do, and then I'll switch
to tmux, I think.

I've started trying Tmux in place of Screen, and I like it, but for the most part, screen has all the functionality I need anyway, and the zmodem support that screen has is actually more useful than you think.

Funny - I've used `screen` for years and never come across zmodem support. I use that feature of SecureCRT a lot, to drop files onto my terminal session
and upload. I'm guessing this is what screen does as well?! I'll have to
check it out.

Sort of. With screen, you set the zmodem setting to "catch", and when you run "sz" or "rz" on the remote machine, screen will pick it up, and prompt you to run "rz" or "sz" on the local machine. Annoyingly, when you send on the local machine, you have to type the path (so it means you have to remember the full filename, there is no selector). But it works. Sometimes you need to add the '-e' option to escape control sequences.

SCP is better, but when you are already logged on, then it saves you opening up another terminal.

Using tmux at the moment, but I'm pretty ambivalent about whether I use screen or tmux. I'm using tmux because the keybindings on how to split a screen are fresh in my head, I don't remember them for screen. I have a menu set to SSH into particular servers, and those shortcuts set up a terminal with screen. Screen has ZMODEM support which I do use.

However I've found that systemd now terminates all your processes when you log out, including detached screen and tmux sessions!

how do you even use zmodem with screen?
do you just run it on auto in the screen session?

You enable zmodem with the "zmodem catch" config option. This will detect and zmodem escape sequences. When it detects one, screen will then prompt you to run the corresponding sz/rz command at your end.

So how it works is this. You start screen, then ssh/telnet to the remote server. On the remote server you initiate either rz or sz depending on whether you want to send or receive, and screen will then bring up a prompt with sz or rz, allowing you to run then on the local end. When you accept that command, the transfer proceeds.

Its convienient when you ssh to a remote server, and just want to send an adhoc file back or forth.

I use Linux, so SCP is an option, but it means starting another shell to run the command. Zmodem means I can do it within the shell.

For Windows users, you can use LePutty, which is Putty with zmodem support. Wouldn't have thought it would still be useful, but it is.

I use MobaXTerm in windows which has a small built-in scp gui where you can click/drag files to transfer them. It's not free, but it's well worth it, especially when you have to deal with and organize over a thousand different servers.

I'll have to take another look at MobaXTerm. We're using a combination of Putty, WinSCP and an autologin plugin for Keepass that's nice.

Keys most places to autologin, and Keepass to automate SSH/RDP elsewhere.

I use Windows on my primary computer, as I play video games, and a lot of the ham radio stuff I have also requires windows (getting any of that stuff to run reliably under WINE is a nightmare I don't want to deal with).

The other 6 computers sitting around me are all running some flavor of Linux, and one runs BSD.

It should be pretty easy to create a web page with links to all the servers people need to access. a browser can auto-launch PuTTY. They'd just need to make sure their key was loaded.
