Command Definitions C-E
DISKUSE
Use
You must have traverse directory entries (TD) and read directory entries (RD) permissions
to each directory contributing to the reported totals. TD access is needed to each directory
component named in dir_name. (Refer to the ALTSEC command in this chapter for
additional information on directory permissions.)
Note that the MPE syntax cannot specify a group.account. MPE syntax only permits
dir.group.acct if dir is a valid MPE name; that is, all uppercase alphanumeric. (If
group.account were specified, it would be interpreted as a file called
group.account.logon_account.)
Directory errors can occur while DISKUSE is collecting file space information. For example,
if you lack traverse directory entries (TD) access to one or more of the lower level
directories, an error occurs.
If ;TREE is specified, you will only be able to see directories that you have TD and RD
access to. DISKUSE stops on the first error encountered. This may result in no data (other
than a header) displayed, or in the case of wildcard names, some directories are seen (up to
the directory where the error occurred). Even in the wildcard directory name case, once an
error is encountered, DISKUSE terminates.
There are several ways to see all disk space used on the system:
• To show the disk space for every directory on the system, enter:
DISKUSE /
• To show only the total system disk space in one line, enter:
DISKUSE /;NOTREE
NOTREE option overrides directory name ending in "/". (CIWARN 9041)
• To display disk space used by all directories directly under the root, enter:
DISKUSE /@
