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
