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  supported  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.  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]
              The  disk  or  partition  image to read, whose format is given with '-i'.  Multiple
              image file names can be given if the image is split  into  multiple  segments.   If
              only  one  image  file  is given, and its name is the first in a sequence (e.g., as
              indicated by  ending  in  '.001'),  subsequent  image  segments  will  be  included
              automatically.

       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
