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 address 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 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.
- -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]
- 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.
