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.
