ISOSIZE(8)                         SG_UTILS                         ISOSIZE(8)



NAME
       isosize - outputs the length of a iso9660 file system

SYNOPSIS
       isosize [-x] [-d <num>] <iso9660_image_file>...

DESCRIPTION
       This  command  outputs  the  length  of an iso9660 file system that is contained 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 <num>
              only  has affect when "-x" is not given. The number output (if no errors) is
              the iso9660 file size in bytes divided by <num>. So if <num>  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 system. One  reason  for
       this  is  that  cd  writers  are  allowed  to add "run out" sectors at the end of a
       iso9660 image.
