Normally if you try to view directories in ls, ls will look inside that directory instead of the directory itself. For example:
You want to find out about the directories in images but images has a ton of files in it.
Running this in the images directory will get you the directory information.
ls -l | grep "^d"
We are simply looking for the first character in our ls to be a 'd'. If so it marks a directory.
