NAME

6       hardlink - Consolidate duplicate files via hardlinks

SYNOPSIS

9       hardlink [-c] [-n] [-v] [-vv] [-h] directory1 [ directory2 ... ]
10

DESCRIPTION

12       This  manual  page  documents  hardlink,  a  program which consolidates
13       duplicate files in one or more directories using hardlinks.
14
15       hardlink traverses one or  more  directories  searching  for  duplicate
16       files.   When it finds duplicate files, it uses one of them as the mas‐
17       ter.  It then removes all other duplicates and places  a  hardlink  for
18       each  one pointing to the master file.  This allows for conservation of
19       disk space where multiple directories on a  single  filesystem  contain
20       many duplicate files.
21
22       Since  hard  links  can only span a single filesystem, hardlink is only
23       useful when all directories specified are on the same filesystem.

OPTIONS

26       -c        Compare only the contents of the files being  considered  for
27                 consolidation.   Disregards  permission,  ownership and other
28                 differences.
29
30       -n        Do not perform the consolidation; only print  what  would  be
31                 changed.
32
33       -v        Print summary after hardlinking.
34
35       -vv       Print  every hardlinked file and bytes saved. Also print sum‐
36                 mary after hardlinking.
37
38       -h        Show help.
