I'm managing my e-books with Calibre. Unfortunately, in there kinda 1000+ duplicates has been created when I was importing 10,000 books.
Also there were some books with no formats available, means there were no books, only covers. So I removed them by this below command-
calibredb list -f title,author_sort,formats | grep ".*\[\]\W*$" | cut -d " " -f 1 | xargs -iXX calibredb remove XX
I ran that command at my Ubuntu 16.04 terminal and it worked perfectly fine.
Now my question is, can you folks help me to generate a command like above to delete or merge the duplicate books at Calibre ? Or any kinda other way to delete or merge those large number of duplicates would be highly appreciated.
N.B. I already tried this tutorial with Find Duplicates (1.6.3) by Grant Drake plugin for Calibre. It's not working with a large number of duplicates.
