（Emacs）如何只显示emacs shell中的最后一个目录？

Question

我想知道是否可以在eShell（Emacs Shell）中仅显示最后一个目录。例如，它目前位于路径/home/user/Programming/C++中。使用eshell的当前设置~/Programming/C++ $，但我只想显示：C++ $。

Yes, it's possible - the prompt is generated by function stored in the eshell-prompt-function variable. You can redefine it to whatever you want. You can define it something like: (lambda () (concat (car (last (split-string (eshell/pwd) "/"))) " $ "))

See EmacsWiki for examples.
