disktype — disk format detector


disktype file...


The purpose of disktype is to detect the content format of a disk or disk image. It knows
about common file systems, partition tables, and boot codes.


disktype can be run with any number of regular files or device special files as arguments.
They will be analyzed in the order given, and the results printed to standard output. There
are no switches in this version. Note that running disktype on device files like your hard
disk will likely require root rights.

See the online documentation at <http://disktype.sourceforge.net/doc/> for some example
command lines.


The following formats are recognized by this version of disktype.

File systems:
FAT12/FAT16/FAT32, NTFS, HPFS, MFS, HFS, HFS Plus, ISO9660, ext2/ext3/ext4, btrfs,
Minix, ReiserFS, Reiser4, Linux romfs, Linux cramfs, Linux squashfs, UFS (some
variations), SysV FS (some variations), JFS, XFS, Amiga FS/FFS, BeOS BFS, QNX4 FS,
UDF, 3DO CD-ROM file system, Veritas VxFS, Xbox DVD file system.

DOS/PC style, Apple, Amiga "Rigid Disk", ATARI ST (AHDI3), BSD disklabel, Linux RAID
physical disks, Linux LVM1 physical volumes, Linux LVM2 physical volumes, Solaris x86
disklabel (vtoc), Solaris SPARC disklabel.

Other structures:
Debian split floppy header, Linux swap.

Disk images:
Raw CD image (.bin), Virtual PC hard disk image, Apple UDIF disk image (limited).

Boot codes:
LILO, GRUB, SYSLINUX, ISOLINUX, Linux kernel, FreeBSD loader, Sega Dreamcast (?).

Compression formats:
gzip, compress, bzip2.

Archive formats:
tar, cpio, bar, dump/restore.

Compressed files (gzip, compress, bzip2 formats) will also have their contents analyzed
using transparent decompression. The appropriate compression program must be installed on
the system, i.e. gzip(1) for the gzip and compress formats, bzip2(1) for the bzip2 format.

Disk images in general will also have their contents analyzed using the proper mapping, with
the exception of the Apple UDIF format.

See the online documentation at <http://disktype.sourceforge.net/doc/> for more details on
the supported formats and their quirks.
