Directory Management System

This Node.js application simulates a directory management system where you can create, move, and delete directories. It reads a sequence of commands and outputs the resulting directory structure.

How to Run

1. Ensure you have Node.js installed on your machine. You can download it from here.

2. Clone or download this repository.

3. Open a terminal and navigate to the directory where the code is located.

4. Run the following command to execute the directory management script:

   node directories.js [filename]

   Replace [filename] with the name of the file containing your commands. If no filename is provided, it will default to commands.txt.

Commands

The application understands the following commands:

• CREATE <directory>: Creates a new directory.
• MOVE <source> <destination>: Moves a directory from the source path to the destination path.
• DELETE <directory>: Deletes a directory.
• LIST: Lists the current directory structure.

Example

Consider the following input:

CREATE fruits
CREATE vegetables
CREATE grains
CREATE fruits/apples
CREATE fruits/apples/fuji
LIST
CREATE grains/squash
MOVE grains/squash vegetables
CREATE foods
MOVE grains foods
MOVE fruits foods
MOVE vegetables foods
LIST
DELETE fruits/apples
DELETE foods/fruits/apples
LIST

The expected output would be:

CREATE fruits
CREATE vegetables
CREATE grains
CREATE fruits/apples
CREATE fruits/apples/fuji
LIST
fruits
  apples
    fuji
grains
vegetables
CREATE grains/squash
MOVE grains/squash vegetables
CREATE foods
MOVE grains foods
MOVE fruits foods
MOVE vegetables foods
LIST
foods
  fruits
  grains
  vegetables
    squash
DELETE fruits/apples
Cannot delete fruits/apples - fruits does not exist
DELETE foods/fruits/apples
LIST
foods
  fruits
  grains
  vegetables
    squash
