Handy script for installing Terraform on Linux Forked from https://github.com/pinterb/install-terraform.sh
Since I needed to handle more than one "current" version of terraform I slightly modified the original to install and use multiple versions.
The script will download always the latest version (ie the first link listed on the release page).
The install path will be ~/bin/terraform/<version> (you can change the BASE_INSTALL_DIR variable in utils.sh).
A .terraform-helperrc file will be created each time to define a simple wrapper function to be able to use the correct version for each terraform stack.
Be sure to source that in your .bash_profile/.bashrc.
In your stacks just create an empty file with the version number that you want to use for that stack, for example:
$ cd my_new_stack
$ touch 0.6.16
$ terraform plan
Terraform wrapper: found 0.6.16
[...]
Will use the terraform executable from ~/bin/terraform/0.6.16/terraform
