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
-d, --divisornumber
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.
