至于颜色
README.md和Makefile,则可以使用LSCOLORS完全自定义。例如:https://github.com/trapd00r/LS_COLORS
That's great. Can you add an underline to lsd for some files and make the color darker?
Yup, we should be able to do whatever lscolors can handle. You can refer to documentation on lscolors here and here. These should give you an idea on how to configure lscolors to your exact specific usecase.
