chooseTerraform() {
  # Choose a specific version of terraform based on binaries being in your path
  # with a `-` separator e.g. $PATH/terraform-v0.11.14, $PATH/terraform-v0.12.1
  select version in $(ls /usr/local/bin/ | grep terraform\- | cut -d '-' -f 2)
  do
    if [[ $version == "" ]]
    then
      echo "Please choose from the available versions!"
      continue
    fi
    file="/usr/local/bin/terraform-${version}"

    # Check if there's already a symlink in place and delete it.
    rm -rf $(find /usr/local/bin -type l -name terraform)
    ln -s /usr/local/bin/terraform-${version} /usr/local/bin/terraform
