I teach an Intro to UNIX/Linux course at a local college and one of my students ask the following question:
Why are some of the files in my directory colored white and others are gray? Are the white ones the ones I created today and the gray are existing files?
As I looked into this I first thought the answer would be in the LS_COLORS variable but further investigation revealed that the color listings were different when using the '-l' switch verses the '-al' switch with the ls command. See the following screen shots:
using ls -l the file named '3' shows as white but using the -al switch the same file shows a gray.
Is this a bug in ls or does anyone know why this is happening?
