[...] too just happened to stumble across a post by another blogger, at the link here which introduced this as an alternative. Had I not seen the post, I wouldn’t know it even [...]

Haven’t you try jet BYOBU? That’s really cool, it is like an upper interface for screen (similar to what could be apt for dpkg) but much easier!
For example:
- install it on the server;
- connect through SSH and launch byobu;
- if you’ll press F2 you will get another console on the same ssh session, pressing F3/F4 you’ll move to the next/previous console.

For more documentation look on google, it will let you do lot of staff.

If the number of SSH connections was the main issue, you could have multiplexed your SSH connections for the same effect without screen or tmux : http://en.wikibooks.org/wiki/OpenSSH/Cookbook/Multiplexing

I’m a screen users too. Look’s like worth to try tmux. Thanks.

For me the difference is significant. Instead of having 2, 3 or 4 SSH connections I’m using only one while programming with my workflow of at least 4 terminals open at the same terminal.

They redraw in the same way, yes, but the savings happens when I’m using multiple panes on a same window. It means a lot to me because I’m connecting trough a GSM modem in a low-signal area.

I couldn’t find this anywhere else, recovering a detached session if it exists or spawning a new one if there are none. I use this in my .bashrc . This is a bit equivalent to screen -RR && exit 0 .

if [ -x `which tmux` ] && [ -z "$TMUX" ]; then
    if tmux ls 2> /dev/null | grep -v ‘(attached)$’; then
        tmux attach && exit 0
    else
        tmux -2 && exit 0
    fi
fi

Can you explain why tmux uses less bandwidth than screen? More efficient redrawing? Is the difference really measurable? How is it possible, since tmux also has TERM=screen, so applications should redraw the screen in the same way, shouldn’t they?

Of course. If you see the snapshot I posted, you will see the fullscreen being used, all the pixels of my tiny-screen being used on-demand out-of-the-box.

I love tmux’s panes, it helps me a lot while writing code. I used 4 terminals before, now is only one with the functionality of 4 or more, on demand.

Can you elaborate a bit more on what tmux does for you that screen doesn’t? You mentioned how you’ve configured tmux, and how you’ve transitioned from screen to tmux, but not what you can now do that you couldn’t before.
