我一直在尝试一些.tmux.conf文件，但现在我想返回到原始/默认配置。我该怎么做？我一直在寻找默认文件，但没有成功。

以下是取自 1.51 版的默认选项列表window-options.c在 OpenBSD-current 的 tmux 源代码中（这是开发版本，经常与 sourceforge 同步）。

还有进一步的键绑定（vi 和 emacs 复制模式和状态行编辑键）定义在mode-keys.c我没有费心去提取。
答案2
您可以使用以下命令获取默认设置
$ tmux -f /dev/null show-options -s \; show-options -g \; list-keys > tmux.defaults.conf
它-f /dev/null指定了一个空配置文件，因此您最终得到的是源代码中硬编码的内容。
一旦将其捕获到文件中，您就可以，理论上，将其用作源文件：
$ tmux unbind-key -a
$ tmux source-file tmux.defaults.conf
我说理论上因为您需要在提取的内容中进行转义，tmux.conf然后才能正确获取。可以unbind-key在加载tmux.conf.我不确定是否有办法集体清除选项。
答案3
其他答案包括一些非常有用的信息，这些信息暗示了答案，但我认为他们还没有完全明确地回答这个问题。
如果我正确理解 tmux 手册页，您可以使用 .reset 将给定选项重置为默认值tmux set -u -g <option>。
我知道一次性恢复所有选项的唯一方法是重新安装 tmux。
我认为 ariane 提供的参考（或至少部分）是在使用tmux show -g、tmux show -g -s和来安装 tmux 后立即生成的，tmux show -g -w以获取会话、服务器和窗口选项。
答案4
tmux从编译的值中获取默认值，/etc/tmux.conf然后由否决~/.tmux.conf。如果后者不存在，它将仅适用于其他值。这意味着您可以删除~/.tmux.conf或将其留空。
在 Ubuntu 12.04 和 Linux Mint 17 上似乎都有一个默认/etc/tmux.conf文件（在这种情况下，将采用编译后的默认值）。
