NAME

       blkcat - Display the contents of file system data unit in a disk image.

SYNOPSIS

       blkcat [-ahswvV] [-f fstype] [-u unit_size] [-i imgtype] [-o imgoffset] [-b dev_sector_size] image [images] unit_addr [num]

DESCRIPTION

       blkcat  displays  num data units (default is one) starting at the unit address unit_addr from image to stdout in different formats (default
       is raw).  blkcat was called dcat in TSK versions prior to 3.0.0.

ARGUMENTS

       -a     Display the contents in ASCII

       -f fstype
	      Specify image as a specific file type.  If 'swap' is given here, the image will be displayed in pages of size 4096 bytes.  If  'raw'
	      is  given,  then	512-bytes is used as the default size.	The '-u' flag can change the default size.  Use '-f list' to list the sup-
	      ported file system types.  If not given, autodetection methods are used.

       -h     Display the contents in hexdump

       -s     Display statistics on the image (unit size, file block size,  and number of fragments).

       -u unit_size
	      Specify the size of the default data unit for raw, blkls, and swap images.

       -i imgtype
	      Identify the type of image file, such as raw or split.  Use '-i list' to list the supported  types.   If	not  given,  autodetection
	      methods are used.

       -o imgoffset
	      The sector offset where the file system starts in the image.

       -b dev_sector_size
	      The  size,  in  bytes,  of  the  underlying  device  sectors.  If not given, the value in the image format is used (if it exists) or
	      512-bytes is assumed.

       -v     Verbose output to stderr.

       -V     Display version.

       -w     Display the contents in an HTML table format.

       image [images]
	      One (or more if split) disk or partition images whose format is given with '-i'.

       unit_addr
	      Address of the disk unit to display.  The size of a unit on this file system can be determined using the -s option.

       num    Number of data units to display.

       The basic functionality of blkcat can also be achieved using dd.  To determine which inode has allocated a given unit, the ifind(1) command
       can be used.

EXAMPLES

       # blkcat -hw image 264 4

       or

       # blkcat -hw image 264

NAME

       mmls - Display the partition layout of a volume system  (partition tables)

SYNOPSIS

       mmls [-t mmtype ] [-o offset ] [ -i imgtype ] [-b dev_sector_size] [-BrvV] [-aAmM] image [images]

DESCRIPTION

       mmls displays the layout of the partitions in a volume system, which include partition tables and disk labels.

ARGUMENTS

       -t mmtype
	      Specify the media management type.  Use '-t list' to list the supported types. If not given, autodetection methods are used.

       -o offset
	      Specify  the  offset  into  the image where the volume containing the partition system starts.  The relative offset of the partition
	      system will be added to this value.

       -b dev_sector_size
	      The size, in bytes, of the underlying device sectors.  If not given, the value in the  image  format  is	used  (if  it  exists)	or
	      512-bytes is assumed.

       -i imgtype
	      Identify the type of image file, such as raw or split.  If not given, autodetection methods are used.

       -B     Include a column with the partition sizes in bytes

       -r     Recurse  into  DOS  partitions and look for other partition tables.  This setup frequently occurs when Unix is installed on x86 sys-
	      tems.

       -v     Verbose output of debugging statements to stderr

       -V     Display version

       -a     Show allocated volumes

       -A     Show unallocated volumes

       -m     Show metadata volumes

       -M     Hide metadata volumes

       image [images]
	      One (or more if split) disk images whose format is given with '-i'.

       'mmls' is similar to 'fdisk -lu' in Linux with a few differences.  Namely, it will show which sectors are not being used so that those  can
       be searched for hidden data.  It also gives the length value so that it can be plugged into 'dd' more easily for extracting the partitions.
       It also will show BSD disk labels for Free, Open, and NetBSD and will display the output in sectors and not cylinders.  Lastly, it works on
       non-Linux systems.

       If  none  of  -a, -A, -m, or -M are given then all volume types will be listed.	If any of them are given, then only the types specified on
       the command line will be listed.

       Allocated volumes are those that are listed in a partition table in the volume system AND can store data.  Unallocated volumes  are  virtu-
       ally created by mmls to show you which sectors have not been allocated to a volume.  The metadata volumes overlap the allocated and unallo-
       cated volumes and describe where the partition tables and other metadata structures are located.  In some volume systems, these	structures
       are in allocated space and in others they are in unallocated space.  In some volume systems, their location is explicitly given in the par-
       tition tables and in others they are not.

EXAMPLES

       To list the partition table of a Windows system using autodetect:

       # mmls disk_image.dd

       To list the contents of a BSD system that starts in sector 12345 of a split image:

       # mmls -t bsd -o 12345 -i split disk-1.dd disk-2.dd
