       combine - combine sets of lines from two files using boolean operations

SYNOPSIS

       combine file1 not file2

rsnapshot-diff

rsnapshot-diff(1)														 rsnapshot-diff(1)

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

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

       -V (more verbose)
	   Be more verbose - as well as listed changes, unchanged files will be listed too.

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

       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.
