-s: only display the grand totals for the names on the command line.
-M: show file names in their OS-provided mixed-case forms, rather than lower-
casing them. Note however that most file systems don't allow files with names
differing only by case, and will ignore case differences when looking for a file.
-?: Display program description.
Note: If the environment variable DU exists, its value is used to establish default
options.
Note: You can override an option that was specified in the environment variable by
following the option with a minus '-' sign. For example, to turn off the -a option,
specify -a-.
