dcat1

Usage

Overview

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
