Compare the contents of a directory with the contents of an image or local device.
tsk_comparedir [-vV] [-n start_inum ] [ -f fstype ] [ -i imgtype ] [ -b dev_sector_size ] [ -o sector_offset ] image [images] comparison_directory
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:
Sector offset for a partition in the image or device to compare with.
Starting inum for a directory in the image to start the comparison at.
verbose output to stderr
Print version
Specify the file system type. Use '-f list' to list the supported file system types. If not given, autodetection methods are used.
The format of the image file, such as raw. Use '-i list' to list the supported types. If not given, autodetection methods are used.
The size (in bytes) of the device sectors. If not given, autodetection methods are used.
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.
To compare the directories in image.dd to those in directory:
# tsk_comparedir ./image.dd ./directory
