The DiskUsage command gives an estimate of the disk space occupied by the
directories specified on the command line.

Patterns can be used to specify the directories.

If no directory is specified, the current directory is used.

Subdirectories are traversed recursively.

A grand total will be printed if more than one directory was specified.

Switches:

    BRIEF:       Do not print information about subdirectories.
    NOBLOCKS:    Suppress the blocks column.
    NOHEAD:      Do not print the headline.
    NOKILOBYTES: Suppress the kilobytes column.
    NOTOTAL:     Do not print the grand total..

    NOBL:        Synonym for NOBLOCKS.
    NOKB:        Synonym for NOKILOBYTES.
    SUMMARY:     Synonym for BRIEF.
