Motivation

tfutils/tfenv: Terraform version manager is great tool for switching the terraform version used in local.

However, There is an issue that it takes extra time to execute the command. (This is referred by terraform executions delayed by ~ 1 second · Issue #196 · tfutils/tfenv). If you want to display the terraform version in the prompt, you will have to wait almost a second every time the it is updated.

This tool can also switch the terraform version. This installs binary from https://releases.hashicorp.com/terraform/ if specified version does not found in your machine. tfenv runs own script instead of binary, but this tool runs binary directly.
