Thanks for this work, but I think I am not a fan of this approach. This is a little bit mix of functionalities. We do go through transformations and we don't transform any old things here. Also why the only frontmatter if the whole file is empty? Also where the new file is put? In provided path? What if we want to provide a file next to another file we traverse?

I think it will be unwise to abstract all Linux commands within the transform configuration ): It's so easy to create this file with simple echo ... > file.

One functionality which would be harder with Linux commands (harder than 3 words) is to add certain file content next to another file we traverse with glob 🤔

I think I would prefer something simple for now like ExtraFiles with content template or something like this 🤔

Also why the only frontmatter if the whole file is empty?

Creating a new file, with just frontmatter, was the use case I was aiming to fulfill with this, as seen here in Thanos.

Also where the new file is put? In provided path? What if we want to provide a file next to another file we traverse?

Yes, it is put in the provided path. For putting a new file next to a particular file we traverse, I think we can just mention path of the file we want to place it next to...but yes, addPath cannot work with glob.

Yes, I see your point. Will try to make this simpler with ExtraFiles and content! 🙂
