BLKCAT(1) General Commands Manual BLKCAT(1) 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 ad- dress 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 deter- mine which inode has allocated a given unit, the ifind(1) command can be used.
