NAME
       rsnapshot-diff - a utility for comparing the disk usage of two
       snapshots taken by rsnapshot

SYNOPSIS
       rsnapshot-diff [-h|vVi] dir1 dir2

DESCRIPTION
       rsnapshot-diff is a companion utility for rsnapshot, which traverses
       two parallel directory structures and calculates the difference between
       them.  By default it is silent apart from displaying summary
       information at the end, but it can be made more verbose.

       In the summary, "added" files may very well include files which at
       first glance also appear at the same place in the older directory
       structure.  However, because the files differ in some respect, they are
       different files.  They have a different inode number.  Consequently if
       you use -v most of its output may appear to be pairs of files with the
       same name being removed and added.

OPTIONS
       -h (help)
           Displays help information

       -H (human)
           Display more human-friendly numbers - as well as showing the number
           of bytes changed, also show MB and GB.

       -i (ignore)
           If verbosity is turned on, -i suppresses information about
           symlinks, directories, and special files.

       -s (show size)
           Show the size of each changed file after the + or - sign.  To sort
           the files by decreasing size, use this option and run the output
           through "sort -k 2 -rn".

       -v (verbose)
           Be verbose.  This will spit out a list of all changes as they are
           encountered, apart from symlink, as well as the summary at the end.

       -V (more verbose)
           Be more verbose - as well as listing changed files, unchanged files
           and symlinks will be listed too.

       dir1 and dir2
           These are the only compulsory parameters, and should be the names
           of two directories to compare.  Their order doesn't matter,
           rsnapshot-diff will always compare the younger to the older, so
           files that appear only in the older will be reported as having been
           removed, and files that appear only in the younger will be reported
           as having been added.
