tfenv: manage different Terraform versions on the same machine

Lately I ran into a problem on my machine. 

And anyone using Terraform could run into the same problem.

How can I manage multiple versions of Terraform at the same time on the same machine?

I have the solution, it's called tfenv!

tfenv

tfenv is a Terraform version manager, whose documentation can be found here:

https://github.com/tfutils/tfenv

Installations steps:

$ brew install tfenv

$ brew link tfenv (optional)

Usage:

- Install a specific version of Terraform (e.g v0.12.29)

$ tfenv install 0.12.29

- Use a specific version of Terraform 

$ tfenv use 0.12.29

- Uninstall a specific version

$ tfenv uninstall 0.12.29

- List installed versions of tf:

$ tfenv list

- List remote available versions:

$ tfenv list-remote
