NAME
dumpisofs - examine an ISO 9660 filesystem image and check it for consistency with the standard

SYNOPSIS
dumpisofs [-x] [-w] [-v] [-V] [-c [-f volume-descriptor-number] [-p sort-type] [-s sort-type]] < image-file-name

DESCRIPTION
dumpisofs examines a file containing the image of an ISO 9660 filesystem and checks it for consistency with the ISO 9660 standard. The image should be provided on standard input.

OPTIONS

-x  Do nothing except check to see if the size of the file as given by the operating system matches the size specified in the header.

-w  Do nothing except read the header and print out volume descriptor information.

-v  Print volume descriptor information.

-V  Print volume descriptor information and directory hierarchies.

-c  Print a report on the consistency of the filesystem.

-f volume-descriptor-number
    Specify which volume descriptor to check for consistency; volume-descriptor-number should be 0 for the first volume descriptor, 1 for the second, etc. By default, all volume descriptors are checked.

-p sort-type
    Specify the sort order used in the consistency check when checking directory hierarchies specified in primary volume descriptors. sort-type may be none (to not check the ordering), lex (for lexicographic ordering), or iso9660 (for ordering as specified by ISO 9660.) The default is iso9660.

-s sort-type
    Specify the sort order used in the consistency check when checking directory hierarchies specified in secondary volume descriptors. sort-type may be none (to not check the ordering), lex (for lexicographic ordering), or iso9660 (for ordering as specified by ISO 9660.) The default is lex.

BUGS
Many images encountered in real life do not conform well to the standard.
