Where can I find all tmux options?

Question

Where can I find a list of all tmux options? I know of tmux list-keys -t which shows you various keybindings and their commands, but I'm looking for a comprehensive list of all possible tmux commands.

Answer 1

I have memorized tmux list-keys | less and tmux show -gw | less (I also check just -g, -w, and -s when I think I'm missing something).

That usually gives me anything I need to know, or set. I use man tmux then /OPTIONS for more.

Also remember that any command you would issue to Ctrl+b, : can also be passed to the tmux cli/cmd though tab-completion is a trick to set up there.

Answer 2

Running man tmux in the terminal displays the manual which has all available options. There are also online versions of the manual (e.g. http://manpages.ubuntu.com/manpages/vivid/en/man1/tmux.1.html)

Answer 3

In case there is no formal documentation I found some of it in the source code. https://github.com/ThomasAdam/tmux/blob/master/mode-key.c for mode mappings

Answer 4

options-table.c at source

• This file has a tables with all the server, session and window * options. These tables are the master copy of the options with their real * (user-visible) types, range limits and default values.

Answer 5

Extract them from manpage

function tmux__list_options {
  local range
  case $1 in
    -s)
      range='/^ {5}Available server options/,/^ {5}Available session options/p'
      ;;
    -e)
      range='/^ {5}Available session options/,/^ {5}Available window options/p'
      ;;
    -w)
      range='/^ {5}Available window options/,/^ {5}Available pane options/p'
      ;;
    -p)
      range='/^ {5}Available pane options/,/^[A-Z]/p'
      ;;
    *)
      range='/^ {5}Available server options/,/^[A-Z]/p'
      ;;
  esac
  man -P cat tmux | sed -En "$range" | grep -E --color=never '^ {5}[a-z]'
}
