这很奇怪。我在我的.bashrc文件中设置了shopt -s autocd，如果我在shell中运行shopt -p，我可以看到它是可用的(并设置)。
但是当我启动tmux shell并运行shopt -p时，自动cd选项不再显示，任何试图移动到没有cd命令前缀的目录的尝试都会失败，并显示一条消息说-bash: /Users/me/some/directory: is a directory
下面是shopt -p 在 tmux…

tmux默认为每个新窗口/窗格创建一个登录shell。这意味着执行的是.bash_profile(也可能是.profile或.bash_login，取决于可用的文件)，而不是.bashrc。有关default-shell和default-conmand选项的信息，请参阅手册页。
(错误消息中当前shell的名称-bash也确认您处于登录shell中，而不是常规的交互式shell。)
