isosize [options] iso9660_image_file

       This  command outputs the length of an iso9660 file system that is con-
       tained in the 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
       (and errors) it will output the  size  of  the  iso9660  filesystem  in
       bytes.  This can now be a large number (>> 4 GB).

       -x, --sectors
              Show the block count and block size in human-readable form.  The
              output uses the term "sectors" for "blocks".

       -d, --divisor number
              Only has an effect when -x is not given.  The value shown (if no
              errors) is the iso9660 file size in bytes divided by number.  So
              if number is the block size then the shown  value  will  be  the
              block count.

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