> Read configured tmux commands; accepts no client-supplied executable input. Returned values may contain executable configuration. Read tmux options at the server, session, window or pane level. Values set at a wider scope are included and marked inherited, because that is where nearly all tmux configuration lives. Omit the name to list them all. Reading history-limit before a long tail tells you how much output the pane can hold before it starts dropping lines.

Server behavior and tool contracts may change. Tool availability depends on the server configuration.
