Terraform fmt is a command-line tool used in the Terraform infrastructure as code (IaC) platform to format and standardize the layout of Terraform configuration files.

This tool helps developers and operators maintain consistency and readability in their codebase by automatically applying a consistent style to their configuration files. The Terraform fmt command rewrites Terraform configuration files in a canonical format based on a set of predefined rules.

This ensures that all code within a project follows the same formatting conventions, making it easier for team members to collaborate and review each other's code. By using Terraform fmt, developers can avoid inconsistencies in code styling, such as indentation, spacing, and line breaks, which can lead to errors and confusion.

This tool helps maintain a clean and organized codebase, making it easier to understand and maintain over time. In addition to improving code readability, Terraform fmt also helps streamline the code review process by ensuring that all code follows the same formatting guidelines.

This can save time and effort for development teams, as they can focus on the content of the code rather than its presentation. Overall, Terraform fmt is a valuable tool for maintaining code quality and consistency in Terraform projects.

By using this command-line tool, developers can ensure that their infrastructure as code is well-organized, easy to read, and free of formatting errors.
