  In this quest, you will learn:
  1. How to create files with `touch`
  2. How to create folders with `mkdir`

requirements:
  - tab

stages:
  - id: start
    name: Click `Start` to begin
    condition:
      command: echo start

        This time, we will learn about the `touch` command.
        First, use `ls` to list the files in your current folder.
        You should find that the folder has no files.
      hint: Enter `ls` to list the files in your current folder

  - id: ls
    name: List the files in the folder
    requirements:
      - start
    condition:
      command: ls
    response:
      content: |
        The terminal shows no output, which means there are no visible files in this folder.
        You can create a file with `touch [filename]`.
        Try creating a file named `hello.txt` in the terminal.
      hint: Enter `touch hello.txt` to create a file

  - id: touch
    name: Create a file with `touch`
    requirements:
      - ls
    condition:
      files:
        - path: /home/commander/hello.txt
          type: file
          exists: true
    exceptions:
      - id: missing_extension
        condition:
          files:
            - path: /home/commander/hello
              type: file
              exists: true
        response:
          content: |
            It looks like you forgot the `.txt` extension.
            Try again and make sure the filename is `hello.txt`.
    response:
      content: |
        The terminal should show no output.
        The file tree on the right now shows the new `hello.txt` file.
        Let's look inside `hello.txt`!
        Use the `cat` command you learned earlier to display its contents.
      hint: Enter `cat hello.txt` to display the contents of `hello.txt`

  - id: cat
    name: Display the contents of `hello.txt` with `cat`
    requirements:
      - touch
    condition:
      command: cat hello.txt
    response:
      content: |
        Huh? There is nothing there!
        That's right. A new file created with `touch` is empty.
        We will learn how to edit file contents in a future lesson.
        Let's create another file!
        Try creating another file named `world.txt` in the terminal.
      hint: Enter `touch world.txt` to create a file

  - id: touch-2
    name: Create another file named `world.txt` with `touch`
    requirements:
      - cat
    condition:
      files:
        - path: /home/commander/world.txt
          type: file
          exists: true
    exceptions:
      - id: missing_extension
        condition:
          files:
            - path: /home/commander/world
              type: file
              exists: true
        response:
          content: |
            It looks like you forgot the `.txt` extension.
            Try again and make sure the filename is `world.txt`.
    response:
      content: |
        Great! You have created your second file.
        The file tree now shows both `hello.txt` and `world.txt`.
        Next, let's create a folder!
        The `mkdir` command creates an empty folder.
        Use `mkdir [folder name]`.
        Try creating a folder named `notes` in the terminal.
      hint: Enter `mkdir notes` to create a folder

  - id: mkdir
    name: Create the `notes` folder with `mkdir`
    requirements:
      - touch-2
    condition:
      files:
        - path: /home/commander/notes
          type: directory
          exists: true
    response:
      content: |
        Great! You have created the `notes` folder.
        Next, we will create a file named `note.txt` inside `notes`.
        First, enter the `notes` folder.
        Remember the `cd` command? Try using it to enter `notes`.
      hint: |
        Enter `cd notes` to enter the `notes` folder
        After typing `cd n`, press `Tab` to complete the folder name

  - id: cd-notes
    name: Enter the `notes` folder
    requirements:
      - mkdir
    condition:
      pwd: /home/commander/notes
    response:
      content: |
        You have entered the `notes` folder.
        Now try creating a file named `note.txt` inside `notes`.
      hint: Enter `touch note.txt` to create a file

  - id: touch-note
    name: Create `note.txt` inside `notes`
    requirements:
      - cd-notes
    condition:
      files:
        - path: /home/commander/notes/note.txt
          type: file
          exists: true
    response:
      content: |
        Great! You have created `note.txt`.
        Congratulations! You have completed this quest!
        In the next quest, you will learn how to copy files and folders.
