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). +.TP +-x +output in humanly readable form the block count and the block +size. Output uses the term "sectors" for "blocks". +.TP +-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. +.PP +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. |
