I tried tmux a while ago, and didn’t like it, can’t remember why. Time to look at it again.

Let’s try it:

$ sudo apt install tmux

That does also require a few libs, libjpeg, lua (?!), etc.

Now the test is that I’m going to run Screen from Portal, and then inside I have Tmux on PiR.

[pir] $ tmux

[pir] $ tmux a  | attach  |  attach-session                # equivalent to -r -d

[pir] $ tmux list-sessions

Tmux has “windows” and “panes”: a window contains 1 or more panes.

Contrary to screen, “split” creates a new “pane” with its own shell. I don’t see how to “bring” a different window pane into the current one like I do with screen.

Contrary to screen, re-attaching preserves the split panes in a window.

Nesting screen in tmux in screen:

• I have this setup: screen > tmux > screen. I know 😕
• Ctrl-a + key for the first screen
• Ctrl-b + key for the first tmux.
• Ctrl-a + a + key does send to the 2nd screen

That actually works well, and it’s better than nesting 3 screen sessions inside each other.
