Table 10-33 Options for the du command

Option	Description
`dir`	Name of the directory.
`--suppressheader`	Suppresses column headings from the output.

If you do not specify dir, then information about the current directory is displayed. dir can contain wildcard characters. See "Wildcard Characters".

The following two values are displayed, both in units of megabytes.

Used_MB - This value does not include mirroring.
Mirror_used_MB - This value includes mirroring.

For example, if a normal redundancy disk group contains 100 MB of data and each file in the disk group is 2-way mirrored, then Used_MB is 100 MB and Mirror_used_MB is roughly 200 MB.
