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.
