dcat - Display the contents of file system data unit in a disk image.
dcat [-ahswvV] [-f fstype] [-u unit_size] [-i imgtype] [-o imgoffset]
image [images] unit_addr [num]
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).
- -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 ’-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,
- -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. 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. 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. To determine
which inode has allocated a given unit, the ifind(1)
command can be used.
# dcat -hw image 264 4
or
# dcat -hw image 264
ifind(1)
