Question: Usually `tmux` will only show as much output as however many rows my terminal currently displays. And then when I detach it, it clears all of its content. I know how to look at scrollback (`ctrl+A`, `[`, `k`, ...), but how can I configure tmux to just print all its output to terminal, as if I wasn't using it at all?

I like `tmux` because I'm awful at remembering to `nohup` certain tasks, and because it makes viewing the output of long-running jobs easier. But I would like to be able to view its scrollback more naturally, by simply *scrolling back* in iTerm2.

Alternatively, if there's a way to do this in `screen`, I can use that too.

Answer: 
I stumbled across an alternative solution on Superuser.com: [Use terminal scrollbar with tmux](https://superuser.com/questions/310251/use-terminal-scrollbar-with-tmux). Add this to your `~/.tmux.conf`:

```
# Pretend our terminal doesn't support alternative screens, and thus all text 
# should be placed into the scrollback buffer when it goes off the top of the 
# screen.

set-option -ga terminal-overrides ',xterm*:smcup@:rmcup@'

```

Works for me with `gnome-terminal` v3.4.1.1 and `tmux` v1.9
In my case, just putting `set-option -g status off` in `.tmux.conf` allows to leave the scrollback in the terminal. But you lose the status bar.
