Knowing how to work with directories and files is essential for developers, system administrators, and anyone automating tasks with Ruby.

1

Create a directory path variable

Create a variable called directory_path and set it to the string "./test_folder".

Ruby

# Create a variable called directory_path and set it to "./test_folder"
# Your code here

Need a hint?

Use a string to store the folder path.

2

Create a variable to hold directory entries

Create a variable called entries and set it to an empty array [].

Ruby

directory_path = "./test_folder"
# Create a variable called entries and set it to an empty array
# Your code here

Need a hint?

Use square brackets to create an empty array.

3

Get directory entries using Dir.entries

Set the variable entries to the result of Dir.entries(directory_path) to get all files and folders inside the directory.

Ruby

directory_path = "./test_folder"
entries = []
# Use Dir.entries with directory_path to get all entries
# Your code here

Need a hint?

Use Dir.entries method with the directory path variable.

4

Print the directory entries

Use puts entries to print each entry in the entries array on its own line.

Ruby

directory_path = "./test_folder"
entries = Dir.entries(directory_path)
# Print the entries array
# Your code here

Need a hint?

Use puts to print each item on a new line.
