## 🚀 Usage
By default, `dotenv-linter` checks all `.env` files in the current directory:
```shell script
$ dotenv-linter
.env:2 DuplicatedKey: The FOO key is duplicated
.env:3 UnorderedKey: The BAR key should go before the FOO key
.env.test:1 LeadingCharacter: Invalid leading character detected
Found 3 problems
It can also fix found warnings. You should use the argument --fix (or its short version -f) for this:
```shell script $ dotenv-linter -f Original file was backed up to: ".env_1601378896"
.env:2 DuplicatedKey: The BAR key is duplicated .env:3 LowercaseKey: The foo key should be in uppercase
All warnings are fixed. Total: 2
