	When you are looking to diagnose how much space you are using you often want to know how much storage the immediate directories are taking in a certain folder. The utility to do this is <code>du</code>. Since NIX operating systems use the concept of <code>..</code> for the previous directory simple file globs like <code>.</code> don't provide exactly what you need since in certain places like your home directories there are a lot of dot files or hidden files (eg. <code>.somename</code>). To identify all files and directories from the current directory you can use something like <code>du -hs .[^.]* *</code>.
