NAME
       hardlink - Link multiple copies of a file

SYNOPSIS
       hardlink [option]...  [directory|file]...

DESCRIPTION
       hardlink is a tool which replaces copies of a file with hardlinks,
       therefore saving space.

OPTIONS
       -h or --help
              print quick usage details to the screen.

       -v or --verbose
              More verbose output. If specified once, every hardlinked file is
              displayed, if specified twice, it also shows every comparison.

       -n or --dry-run
              Do not act, just print what would happen

       -f or --respect-name
              Only try to link files with the same (basename).

       -p or --ignore-mode
              Link/compare files even if their mode is different. This may be
              a bit unpredictable.

       -o or --ignore-owner
              Link/compare files even if their owner (user and group) is
              different. It is not predictable

       -t or --ignore-time
              Link/compare files even if their time of modification is
              different. This will retain the newest timestamp, unless -m or
              -M is given.

       -m or --maximize
              Try to maximize the link count of the files.

       -M or --minimize
              Try to minimize the link count of the files.

       -x or --exclude
              A regular expression which excludes files from being compared
              and linked.

       -i or --include
              A regular expression to include files. If the option --exclude
              has been given, this option re-includes files which would
              otherwise be excluded. If the option is used without --exclude,
              only files matched by the pattern are included.


ARGUMENTS
       hardlink takes one or more directories which will be searched for files
       to be linked.


BUGS
       hardlink assumes that the trees it operates on do not change during
       operation. If a tree does change, the result is undefined and
       potentially dangerous. For example, if a regular file is replaced by a
       device, hardlink may start reading from the device. If a component of a
       path is replaced by a symbolic link or file permissions change,
       security may be compromised. Do not run hardlink on a changing tree or
       on a tree controlled by another user.
