NAME

       tsk_comparedir  -  compare  the  contents  of a directory with the contents of an image or
       local device.

SYNOPSIS

       tsk_comparedir [-vV] [-n start_inum ] [ -f fstype ] [ -i imgtype ] [ -b dev_sector_size  ]
       [ -o sector_offset ] image [images] comparison_directory

DESCRIPTION

       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.

EXAMPLES

       To compare the directories in image.dd to those in directory:

            # tsk_comparedir ./image.dd ./directory
