Directories:


File and directory paths in UNIX use the forward slash "/" 
to separate directory names in a path.

examples:

/              "root" directory

It's not really a tutorial - you'll still have work to do in getting things operational. It doesn't cover the fine points (and there are a lot of them), but I hope it will give you enough background to begin using them decently.
