Great book so far!
It seems the only way I can get 256 colors is to start tmux with “tmux -2”. I have “set -g default-terminal “screen-256color” in my ~/.tmux.conf and I have configured iTerm2 to allow 256 colors. The perl colortest shows 256 colors when run from iTerm2, but not when run from within tmux running from iTerm2. Anything else I can check or do I have to start tmux with “tmux -2”?
