Sure it is. You will need to write a small shell script to scan
your disk volume and calculate the checksum of each file. When
ever it finds a duplicated checksum, then it copies the file into
the central store and replaces the on-disk copies with symbolic
links. That's fairly trivial to write.
However, I have to wonder if this is at all worthwhile. Quite apart
from arguments along the lines of 'disk is cheap' and that the
effort required to do this is out of all proportion to the amount of
such duplicated files on the vast majority of systems, you're also
putting all your eggs in one basket. All it takes is one idiot and
you'll be recovering the one copy of your valuable document from
backup.
Cheers,
Matthew
