tsk_comparedir compares the contents of image to the contents of comparison_directory. This can be
useful for detecting rootkits and when testing. Rootkits can be detected by comparing the contents of a
local directory and a local raw device. The rootkits typically don't hide data when it is read directly
from the raw device.
The arguments are as follows:
-o sector_offset
Sector offset for a partition in the image or device to compare with.
-n start_inum
Starting inum for a directory in the image to start the comparison at.
-v verbose output to stderr
-V Print version
-f fstype
Specify the file system type. Use '-f list' to list the supported file system types. If not
given, autodetection methods are used.
-i imgtype
The format of the image file, such as raw. Use '-i list' to list the supported types. If not
given, autodetection methods are used.
-b dev_sector_size
The size (in bytes) of the device sectors. If not given, autodetection methods are used.
image [images]
The disk or partition image to read, whose format is given with '-i'. Multiple image file names
can be given if the image is split into multiple segments. If only one image file is given, and
its name is the first in a sequence (e.g., as indicated by ending in '.001'), subsequent image
segments will be included automatically.
