linux - .dircolors does not affect existing files, only new files

Question

I recently decided that the terminal color scheme that Ubuntu uses is not optimal. I have edited .dircolors and it worked...for the most part. The issue I am having is I added two custom file extensions to .dircolors which are .R and .cpp. I wanted to make these different colors, but it only applies if I create a new file, say test.R or test.cpp, not for my already existing .R and .cpp files.

Any ideas why existing ones are not taking on the new color settings in .dircolors?

这可能是因为~/.dircolors不是ls直接读取，而是在shell启动时用于设置使用的环境LS_COLORS变量ls。我敢打赌，您在列出目录时使用了两个不同的终端，一个是在修改~/.dircolors. 使更改在现有终端使用中生效eval $(dircolors ~/.dircolors)。

还根据文件的模式分配颜色。例如，您的旧文件可能是可执行文件，因此优先于您定义的文件获得该颜色。在我的系统上，这些基于模式的颜色用于 setuid 和 setgid 文件、具有功能的文件和可执行文件。
