NAME¶
disktype
—
disk format detector
SYNOPSIS¶
DESCRIPTION¶
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.
USAGE¶
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.
- Partitioning:
- 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.
