I am using the “Remove Duplicate Cards” addon available at https://ankiweb.net/shared/info/95590040 .

To install it

start anki on the command line
-> Tools -> Add-ons
-> Get Add-ons
-> enter the code displayed on the addon page (ex:- 95590040)

Notes:

• The account on https://ankiweb.net/ can be synchronised with anki (installed on a Debian machine). The advantage of the Debian version is that you can delete the cards as needed. The online version does not support card deletion. I am currently using

% anki --version
anki 2.1.8

% dpkg -l anki | grep ^ii
ii  anki           2.1.8+dfsg-1 all          extensible flashcard learning program
