       isosize - outputs the length of a iso9660 file system

       isosize [-x] [-d ] ...

       This command outputs the length of an iso9660 file system that is con-
       tained in given file. That file may be a normal file or a block device
       (e.g.  /dev/hdd  or  /dev/sr0).  In  the  absence  of any switches (or
       errors) it will output the size of the iso9660 file system  in  bytes.
       This can now be a large number (> > 4 GB).

       -x     output  in  humanly readable form the block count and the block
              size. Output uses the term "sectors" for "blocks".

              only has affect when "-x" is not given. The number  output  (if
              no  errors) is the iso9660 file size in bytes divided by .
              So if  is the block size then the output  number  will  be
              the block count.

       The  size  of the file (or block device) holding a iso9660 file system
       can be marginally larger than the actual size of the iso9660 file sys-
       tem.  One  reason  for this is that cd writers are allowed to add "run
       out" sectors at the end of a iso9660 image.
