If I understand set_metadata correctly it only accepts an opf file as input which I don't have and it only accepts book id to address it which I don't have.
To get the id I could use the list command with some grepping & cutting, slow... but ok.
If I use set_metadata does it overwrite ALL the metadata currently associated with the given ebook?
If so I would have to ask calibre for the OPF file with show_metadata --as-opf, modify it adding the isbn and then use set_metadata... ¿right?
