NAME

       forensics-colorize - show differences between files using color graphics

SYNOPSIS

       filecompare [-b size[bkmgpe]] [-Vh] FILE1 FILE2

       colorize [-h|-V] [-w <num>] [-ovd] FILES

DESCRIPTION

       forensics-colorize  is  a  set  of  tools to visually compare large files, as filesystem images, creating
       graphics of them. It is intuitive because the produced graphics provide a quick and perfect  sense  about
       the percentage of changes between two files.

       Comparing  large  textual  files  using  a  simple  diff  can produce a very big result in lines, causing
       confusion. On the other hand, diff is improper to compare binary files.

       forensics-colorize uses two command line programs: filecompare and colorize.  The filecompare command  is
       used  to  create  a  special and auxiliary input file for colorize. The colorize command will generate an
       intuitive graphic that will make easier to perceive the level of changes  between  the  files.  In  other
       words, you can use the filecompare command to generate a graphic to be analyzed by colorize command.

OPTIONS FOR FILECOMPARE

       -b     Set  block  size  with  optional  suffix b, k, m, g, p, or e. Note that the program will output at
              least one complete block. Make sure that you have enough disk space!

       -t     Use transitional colors instead of default red or green.

       -V     Display version number and exit.

       -h     Display this help message.

OPTIONS FOR COLORIZE

       -d     Change direction data flows. Default is down or right.

       -o     Change image orientation. Default is vertical.

       -v     Verbose mode.

       -w     Set output image width, defaults to 100.

       -V     Display version number and exit.

       -h     Display this help message and exit.

EXAMPLES

       To generate an initial graphic between 'test1' and 'test2' files to be analyzed by colorize:

           $ filecompare test1 test2 > test.fc

       To analyze the result:

           $ colorize test.fc

       The last command will generate the test.fc.bmp file. You can open it using a  trivial  image  viewer,  as
       sxiv  or similar. If using default parameters for the both commands (filecompare and colorize), unchanged
       parts will be shown as green and changed parts will be colorized with red.

       To get larger or smaller final graphics, use the -b option for the 'filecompare' command. As an  example,
       the following command will produce a result greater than the default:

           $ filecompare -b 64 test1 test2 > test.fc

NOTE

       In  most  cases,  the  default  block  size is the same of the logical disk sector value (now a days, 512
       bytes). Try 'fdisk -l' or 'gdisk -l /dev/<disk>' to find the right value.
