• Description:
  Terraform is an open-source Infrastructure as Code (IaC) tool that allows you to provision and manage infrastructure in a declarative way. Before you can use Terraform to create resources, you must install it on your system. The installation process on Ubuntu/Linux involves downloading the Terraform binary, unzipping it, moving it to a directory in your PATH, and verifying the installation. This ensures that Terraform commands can be executed from anywhere in the terminal.

•  Step 1 — Update System Packages
   Update system:

  sudo apt update
      

   Updates the package index to make sure you can install the latest versions of software.
•  Step 2 — Install Required Tools
   Install required tools:

  sudo apt install -y wget unzip
      

   Installs wget to download files and unzip to extract compressed files.
•  Step 3 — Download Terraform
   Download Terraform binary:

  wget https://releases.hashicorp.com/terraform/1.6.3/terraform_1.6.3_linux_amd64.zip
      

   Downloads the Terraform binary zip file from the official HashiCorp release page.
•  Step 4 — Extract the Terraform Binary
   Extract the downloaded file:

  unzip terraform_1.6.3_linux_amd64.zip
      

   Unzips the downloaded file to get the terraform executable.
•  Step 5 — Move Terraform to a System PATH
   Move Terraform binary:

  sudo mv terraform /usr/local/bin/
      

   Moves the binary to /usr/local/bin/ so you can run terraform from anywhere in the terminal.
•  Step 6 — Verify Installation
   Verify Terraform installation:

  terraform -v
  terraform version
      

   Checks that Terraform is installed correctly and displays the installed version.
