Version 2.09


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).


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


Switch Purpose
-a Display the contents in ASCII
-f 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 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.


# dcat -hw image 264 4


# dcat -hw image 264


dcat first appeared in TCTUTILs v1.0 as bcat.
