hardlink(1)hardlink(1)NAMEhardlink - Consolidate duplicate files via hardlinks
SYNOPSIShardlink [-c] [-n] [-v] [-vv] [-h] directory1 [ directory2 ... ]
DESCRIPTION
This manual page documents hardlink, a program which consolidates
duplicate files in one or more directories using hardlinks.
hardlink traverses one or more directories searching for duplicate
files. When it finds duplicate files, it uses one of them as the mas‐
ter. It then removes all other duplicates and places a hardlink for
each one pointing to the master file. This allows for conservation of
disk space where multiple directories on a single filesystem contain
many duplicate files.
Since hard links can only span a single filesystem, hardlink is only
useful when all directories specified are on the same filesystem.
OPTIONS-c Compare only the contents of the files being considered for
consolidation. Disregards permission, ownership and other
differences.
-n Do not perform the consolidation; only print what would be
changed.
-v Print summary after hardlinking.
-vv Print every hardlinked file and bytes saved. Also print sum‐
mary after hardlinking.
-h Show help.

BUGShardlink assumes that its target directory trees do not change from
under it. If a directory tree does change, this may result in hardlink
accessing files and/or directories outside of the intended directory
tree. Thus, you must avoid running hardlink on potentially changing
directory trees, and especially on directory trees under control of
another user.
