  <p>The only differences are that it will ONLY embed the metadata, and non of the additional options that the Polishing function has available. It will also show the progress as a percentage tab on your screen, and not as a "Job" in the bottom right-hand corner. </p>

  (Asked by: username_0 on 2013-12-25)
  
  I own many EPUB books (Spanish, English). Some have the name of the author wrong, such as "Esquivel, Laura" instead of "Laura Esquivel". And have the name of series in book title, where it does not belong.
  
  I can change this in Calibre so things are right. But when I open the book and look at the metadata it is still wrong **in** the book. After I convert these from epub to epub, and author name are OK in metadata. But this is slow, and sometime change the layout of the book.
  
  Is there a better way (I read here about editing the EPUB books myself, but this seems too cumbersome for the many books I have)?
  
  **Tags:** epub, calibre, metadata

  As you are on Linux, the way to do this is to change to the directory at the base of your library and do:
  find . -name "*.epub" -exec /bin/bash -c 'ebook-polish --opf="$(dirname "$0")/metadata.opf" "$0" ' {} \;
  
  This way you polish them all in one go.
