    "The terminal is a way of interacting with our computer, but instead of doing it through icons and mouse movements, as you are used to doing (and it is what we know as GUI (Graphical User Interface)), those interactions are carried out with lines of commands. And that's why the terminal is a CLI (Command Line Interface).\n",
    "\n",
    "In the case of terminal, many terms are used interchangeably: bash, shell, zsh, iTerm, etc. That is, all of these are \"programs\". Although we are not going to delve into it.\n",
    "\n",
    "Either if you're a macOS 🍎 or Linux 🐧 user, the terminal you will be using will use the Bash language.\n",
    "\n",
    "On Windows 🪟, however, things are a bit different. The Windows CLI, also known as cmd.exe or Command Prompt is different, although it shares many similarities in syntax, there are also many incompatibilities.\n",

    "For example, the `ls` command used on both mac and Linux is equivalent to the `dir` in cmd.exe\n",

    "On the other hand, Bash is not a terminal. It's also not the only shell available. In fact, we can see the available shells on our machine by looking at the contents of the /etc/shells file. If we deem it necessary, we can assign common users something else (other than Bash). This way we can restrict the scope of what they can do using the command line. Of course, it is the administrator who decides this. There is also ZSH, another form of terminal:\n",
