LS_COLORS environmental variable lets you decide on colours for different file types for ls command, such as, directories, regular files, links etc. I suppose that dot files are considered a variation of the Linux file types and not a type on its own hence there is no option for specifying a display colour for them.Is there any (other) way you can make ls listings show hidden files in a different colour?
How to colourise hidden files in `ls` file listings?
