IPFS folders are pretty simple objects, which can be edited with a text editor, given the right input and output filters.

vidir from the moreutils software collection offers a feature to edit folders pretty easily, like rename files.

I think such an edit functionality would be pretty neat for IPFS as well. Instead of numbered lines, the name could be the first entry, while the second one is the cid.

This also allows for fast replace of several files in a folder, if you have some new CIDs uploaded, without having to type in each replacement as a command.

If not an MFS directory is specified, but a CID, the new CID should be printed after quitting the editor.
