This small utility will fetch all the users and emails from a Cognito User Pool of your choice and print a nice file for you.
You can compile it yourself:
```sh cargo install cognito-user-reader # for AWSCLI 1
cargo install cognito-user-reader --features awscli2 # for AWSCLI 2 ```
or you can download the executable from GitHub releases and add it to your path.
You need to have previously installed awscli.
This crate supports both aws-cli versions 1 and 2. By default it will assume aws-cli 1 so if you're using version 2 you have the awscli2 feature available.
Depending on how you have configured AWS, you may need to use something similar to assume-role before using cur in order to access the data:
bash
assume-role your-env
Then, just execute:
bash
cur <pool_id> [-p] [-s] [-a custom:company] [-i "id1" "id2"] [-e "a@email.com" "b@email.com"] [-n] [-m] [-x 20] [-c 2020-02-10]
You will see a new cognito_users.csv file in your working directory with all your user's emails.
If you want to learn more about the options of this cli just execute cur -h.
