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). +.SH OPTIONS +.TP +.BR \-x , " \-\-sectors" +Show the block count and block size in human-readable form. +The output uses the term "sectors" for "blocks". +.TP +.BR \-d , " \-\-divisor " \fInumber\fR +Only has an effect when +.B \-x +is not given. The value shown (if no errors) +is the iso9660 file size in bytes divided by +.IR number . +So if +.I number +is the block size then the shown value will be the block count. +.PP +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. +.SH EXIT STATUS +.RS +.PD 0 +.TP +.B 0 +success +.TP +.B 1 +generic failure, such as invalid usage +.TP +.B 32 +all failed +.TP +.B 64 +some failed +.PD +.RE +.SH AVAILABILITY +The isosize command is part of the util-linux package and is available from +.UR https://\:www.kernel.org\:/pub\:/linux\:/utils\:/util-linux/ +Linux Kernel Archive +.UE . -- cgit v1.2.3
