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

In your working directory, create a .env file based on the example provided in example.env
Install the envrun command to load environment variables from that file:
- go install github.com/fgm/envrun@latest
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
Run the command in read-only mode
- $ envrun go run ./docs/osinet/cmd/duplicates
- it should not display anything since the collection is empty
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.
Now adjust configuration for the actual collection you want to check.
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
