Of possible relevance to future readers of this thread, I found another post in this forum about doing global find & replace on your Obsidian vault — which could help in the task of unifying links (until a ‘merge notes’ feature comes along).
To paraphrase @akaalias’s technique for the present use case:
- Install Atom from https://atom.io/
- Open vault directory in Atom
- Use “Find” → “Find in Project”
- Find all “[[verde]]” to replace with “[[green]]”
- Replace all
- Find all “[[verde|” to replace with “[[green|”
- Replace all
To also replace all unlinked mentions of “verde”, you could Replace All “verde” with “green” instead.
There are other text editors out there that do global find/replace for a folder of files. BBEdit for instance.
