See the comment I made to the sibling comment. For a tl;dr, you can use the following to find files that have more than one tag: find -L tags/tag1 tags/tag2 -xtype l | sort | uniq -d The lesson here is that being able to use command-line tools makes up for perceived limitations of the filesystem model. Edit: After testing, I found the following works great: find -L tags/tag1 tags/tag2 -xtype l | xargs readlink -f | sort | uniq -d
