From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I have exactly the same problem.
I got as far as using
fdupe
to identify duplicates and delete the extras. It was slow.Thinking about some of the other comments... If you use a tool to create hardlinks first, then one could then traverse the entire tree and deleting a file if it has more than one hardlink. The two phases could be done piecemeal and are cancelable and restartable.
That sounds doable. I would however not trust my self to code something bug free on the first go xD
Backup backup backup! If you have btrfs them just take a snapshot first: instantly.
One could do a non-destructive rename first. E.g. prepend
deleteme.
to the file name, sanity check it, then 'rollback' by renaming back without the prefix or commit and delete anything with the prefix.
