NAME
isosize - outputs the length of an 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 sys- tem. One reason for this is that cd writers are allowed to add "run out" sectors at the end of a iso9660 image. sg3_utils-0.91 December 2000 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 filesys- tem. 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/>. util-linux June 2011 ISOSIZE(8)
