Description

In Unix, the user has the option to specify a -s flag:
-s Display an entry for each specified file. (Equivalent to -d 0)

Instead of providing data for the subdirectories of the arguments, du prints the total usage of each argument, without printing subdirectories.

This is very convenient for those looking to find how much space is used by a particular branch, without requring them to add up all the sub-usages.
