NAME
       isosize - output	the length of an iso9660 filesystem

SYNOPSIS
       isosize [options] iso9660_image_file

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

OPTIONS
       -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.

EXIT STATUS
	      0	     success
	      1	     generic failure, such as invalid usage
	      32     all failed
	      64     some failed

AVAILABILITY
       The isosize command is part of the util-linux package and is  available
       from Linux Kernel Archive <https://www.kernel.org/pub/linux/utils/util-
       linux/>.
