isosize(8)


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.

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/.
