How to Use tfenv to Manage Multiple Terraform Versions

Tfenv is a version manager for Terraform inspired by rbenv, which enables users to install multiple versions of Terraform and switch between them easily. This can be useful when working on projects with different customers or ensuring backward compatibility. Tfenv can be installed on MacOS using Homebrew, Linux via the Arch User Repository (AUR), or manually on Windows Subsystem for Linux (WSL2). Users can install specific Terraform versions, set a default version, and view available options. The latest available version can also be conveniently installed. Tfenv is an open-source command line program that helps manage and switch between multiple versions of Terraform.
