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 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 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.

EXIT STATUS
       0
           success

       1
           generic failure, such as invalid usage

       32
           all failed

       64
           some failed
