  • cd is a command used to change directories
  • ~ is an alias recognized by the shell to reference the home directory

• Execute pwd to display the current working directory to verify that the command has executed properly.
• Execute ls to verify the contents of this directory.

Part 3 - Create a New Project Directory

• Execute mkdir my-first-project from the dev directory to create a new directory named my-first-project in the dev directory
• Execute ls to verify that the directory has been created properly.
• Execute cd ./my-first-project to change the current working directory to the newly created directory.
• cd ./my-first-project can be read verbally as “change directory to current working directory. From here, navigate to directory named my-first-project”
  • cd is a command used to change directories
  • . is an alias recognized by the shell to reference the current working directory
  • / is a symbol used to express “from here, navigate to”
• Execute pwd to verify that you have navigated to the directory properly.

Part 4 - Create Directory Named empty-directory

• Execute mkdir empty-directory from the my-first-project directory to create a new directory, named empty-directory
• Execute ls to verify that the newly created directory, named empty-directory, has been created in the my-first-project directory.
• Execute cd ./empty-directory to change the current working directory to the newly created directory
• Execute pwd to verify that you have navigated to the directory properly.
• Execute ls to verify that this directory is empty.

Part 5 - Navigate Back to my-first-project directory

• Execute cd .. to navigate to the parent directory of the current working directory.
  • .. is an alias recognized by the shell to reference the parent directory.
  • A parent directory is a directory which contains another directory.
    • (for example, my-first-project is a child directory of the parent directory named dev)
• Execute pwd to verify that you have navigated to the directory properly.
• Execute ls to verify this directory contains a directory named empty-directory.

Part 7 - Create Directory Named non-empty-directory

• Execute mkdir non-empty-directory from the my-first-project directory to create a new directory named non-empty-directory.
• Execute ls to verify that the newly created directory, named non-empty directory has been created in the directory named my-first-project.
• Execute cd ./non-empty-directory from the my-first-project directory to change the current working directory to non-empty-directory.
• Execute pwd to verify that you have navigated to the directory properly.

Part 8 - Create Directories Within non-empty-directory

• Execute mkdir child-directory-1 to create a new directory in the non-empty-directory
• Execute ls to verify that the newly created directory, named child-directory-1 has been created in directory named non-empty-directory.`
• Execute mkdir child-directory-2 to create a new directory in the non-empty-directory
• Execute ls to verify that the newly created directory, named child-directory-2 has been created in directory named non-empty-directory.`

Part 9 - Create Files Within non-empty-directory

• Execute touch some-file to create a new file in the non-empty-directory
• Execute touch some-text-file.txt to create a new text file in the non-empty-directory
• Execute touch some-webpage-file.html to create a new webpage file in the non-empty-directory
• Execute touch some-mp3-file.mp3 to create a new mp3 file in the non-empty-directory

• Execute ls to verify that each of the child-resources are displayed

    child-directory-1
    child-directory-2
    some-file
    some-mp3-file.mp3
    some-text-file.txt
    some-webpage-file.html
  

Part 10 - Open File in nano editor

• Execute nano some-text-file.txt to open the file named some-text-file.txt in the nano-editor.
• Enter your name in the nano editor.
• From the keyboard, hold Ctrl and press X to exit the editor
• From the keyboard, press Y, when prompted to Save modified buffer.
• From the keyboard, press Enter, when prompted to Save File Name.
• Execute cat some-text-file.txt to verify that the contents entered in the nano editor have been saved in the some-text-file.txt file.

Part 11 - Navigate Back to my-first-project directory

• Execute cd .. to change to the parent directory of the current working directory.
  • .. is an alias recognized by the shell to reference the parent directory.
  • A parent directory is the directory which contains another directory.
    • (for example, non-empty-directory is a child directory _ of the _parent directory named my-first-project)
• Execute pwd to verify that you have navigated to the directory properly.

• Execute rmdir ./non-empty-directory to verify that a directory that is not empty cannot be deleted via the command rmdir.
• Execute ls to verify that the current working directory still contains a directory named non-empty-directory
• Execute rm -rf ./non-empty-directory to delete the the directory containing the content created in Part 9 and Part 10
