1  REPORT
   The report option generates a file and free space report of the
   disk. Also, a graph table is made which gives a quick overview on
   the free space distribution of the disk. DFU creates a number of
   DCL symbols corresponding to the output of the report.

   Format

     REPORT  device
 

2  Qualifiers
 

/APPEND

   /APPEND=filename

   Same as /OUTPUT, but the output will be appended to the file if
   it already exists. Thus, output from multiple DFU commands can be
   put in the same output file. If the file does not exist it will
   be created.
 

/GRAPH

      /GRAPH
      /NOGRAPH (default)

   This qualifier enables the graph output of the free space
   distribution for the disk. The default behavior is not to display
   the graph output.
 

/OUTPUT

   /OUTPUT=filename This qualifier redirects the output from DFU to
   an output file.
 

/NOBITMAP

   Skip the bitmap statistics report.
 

/NOFILE

   Skip the file statistics report.
 

/NOVOLUME

   Skip the volume info report.
 

/STATISTICS

      /STATISTICS
      /NOSTATISTICS (default)

   Controls whether CPU and I/O consumption of the command are
   shown.
 

/UNIT

   /UNIT=BYTES or BLOCKS

   Report sizes in units of bytes or blocks. The default behavior is
   to report sizes as block units.
 

/USAGE

      /USAGE(=uic or identifier)

   Generate a diskblock usage report. DFU will report per
   UIC/Identifier the blocks used/allocated, and the number of file
   headers used. If diskquota is enabled a third column will be
   added to the report with the blocks used according to QUOTA.SYS.
   If an UIC or Identifier is entered then only that UIC will be
   reported. The diskquota used must satisfy the rule :

   QUOTA used = blocks allocated + # of file headers.

   Symbols The following symbols are created. The names should be
   reasonably self explanatory. The values shown here are examples
   to demonstrate the expected format.
