Terraform echo workspace before running apply or output command

terraform_echo_workspace.sh

# Run tf with echo tf-workspace
tf_with_tf_workspace() {
  if [[ "$@" == "apply" ]] || [[ "$@" == "output" ]];
    then
      \terraform workspace list;
  fi
  \terraform "$@";
}

alias tf="terraform"
alias terraform="tf_with_tf_workspace"

Add these lines to ~/.bashrc (or ~/.zshrc). It also creates the shorter tf alias to run terraform
