I noticed some duplicate files under /usr/share/man so I installed and ran dupd(1).
man(1) pages can be plain text or gzip format so these files are already quite small.
For any man page that describes two or more commands or functions, the file appears under each name so that it can be found by the man(1) utility. This results in a lot of duplicates. Just how much data was being duplicated? According to dupd it's about 31 megabytes. Half of the duplication is under section 3.
Play with the commands 'dupd scan', 'dupd report' and 'dupd ls' to see.
The duplicate files could be replaced with symlinks but the effort probably doesn't justify the savings.
