rsnapshot-diff - a utility for comparing the disk usage of two
snapshots taken by rsnapshot
rsnapshot-diff [-h|vVi] dir1 dir2
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.
Displays help information
Display more human-friendly numbers - as well as showing the number
of bytes changed, also show MB and GB.
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".
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.
