- [`command`](/en/ocaml/latest/reference/libtmux-hook-command/) (struct): A tmux command and its distinct arguments. Setting a hook encodes these as command data; it does not concatenate arguments into shell code. Argument-specific tmux behavior, including format expansion, still applies when the hook runs.
