DCAT(1) DCAT(1) NAME dcat - Display the contents of disk "chunks" from a forensic image SYNOPSIS dcat [-ahswvV] [-f fstype] [-u unit_size] [-i imgtype] [-o imgoffset] image [images] unit_addr [num] DESCRIPTION dcat displays num data units (default is one) starting at the unit address unit_addr from image to stdout in different formats (default is raw). The image should be created using dd(1). The arguments are as follows: -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 the -? argument to display supported types. If not given, the default type for the platform is 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, dls, and swap images. -i imgtype Identify the type of image file, such as raw or split. Raw is the default. -o imgoffset The sector offset where the file system starts in the image. Non-512 byte sectors can be specified using @ (32@2048). -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 dcat can also be achieved using dd(1). To determine which inode has allocated a given unit, the ifind(1) command can be used. EXAMPLES # dcat -hw image 264 4 or # dcat -hw image 264 SEE ALSO dd(1), ifind(1) HISTORY dcat first appeared in TCTUTILs v1.0 as bcat. AUTHOR Brian Carrier User Manuals JAN 2005 DCAT(1)
