NAME
       isosize - outputs the length of a iso9660 file system

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

DESCRIPTION
       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".

       -d 
	      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.
