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 contained in the speci-
       fied file.  This file may be a normal file or a block device (e.g. /dev/hdd or  /dev/sr0).
       In  the  absence  of  any  options  (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 filesystem.  One reason for  this  is  that  cd
       writers are allowed to add "run out" sectors at the end of an iso9660 image.

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