Use

A CLI command to find duplicate values in a MongoDB collection.

1. In your working directory, create a .env file based on the example provided in https://code.osinet.fr/fgm/mongodb_duplicates/src/master/example.env
2. Install the envrun command to load environment variables from that file:
   • go install github.com/fgm/envrun@latest
3. Adjuster your .env. For the first check, configure it for an empty collection in an empty database:
   • MONGODB_URL: default = mongodb://localhost:27017
   • MONGODB_DB: default = test
   • MONGODB_COLLECTION: default = test
   • MONGODB_FIELD: the duplicate field. Default = email
4. Run the command in read-only mode
   • $ envrun go run ./docs/osinet/cmd/duplicates
   • it should not display anything since the collection is empty
5. Re-run the command with seed generation. The seed data will remain in the collection.
   • $ envrun go run ./docs/osinet/cmd/duplicates -command seed
   • user1@example.com: 3
   • user2@example.com: 2
   • Resultat show show 3 duplicates of user1 and 2 of user2.
6. Now adjust configuration for the actual collection you want to check.
7. Run the command in read-only mode
   • $ envrun go run ./docs/osinet/cmd/duplicates
   • It will give you the values of the field for which duplicates exist, and the document count for that value
