A hardlink is a name for a file. With most filesystems supported
by Linux systems, a single file can have multiple names; each of those
is called a hardlink. The link count of a file is the second column in the
output of the /bin/ls command.
/usr/bin/hardlink.py finds files that are identical, unlinks (removes)
occurrences that have the same content and then creates a hardlink to the
twin file as a substitute. Since the name of a file in its directory entry
is the only additional space requirement of an additional hardlink, each
time hardlink.py creates a hardlink the disk usage of the removed file is
Note that since files are objects that are contained in a filesystem,
hardlinks across filesystem boundaries are not possible.
Use "hardlink.py -h" for a full description of the program's options.
