Set a variable for the directory name

Create a variable called dir_name and set it to the string test_folder.

Linux CLI

mkdir test_folder
touch test_folder/file1.txt test_folder/file2.txt

# Set the directory name variable
dir_name="test_folder"
# Your code here

Use dir_name="test_folder" to store the folder name in a variable.

3

Remove the directory and its contents

Use the rm -r command with the variable dir_name to remove the directory and everything inside it.

Linux CLI

mkdir test_folder
touch test_folder/file1.txt test_folder/file2.txt
dir_name="test_folder"

# Remove the directory and its contents
rm -r "$dir_name"

Use rm -r "$dir_name" to delete the folder and all files inside it.

4

Confirm the directory removal

Print the message "Directory test_folder removed successfully." to confirm the folder was deleted.

touch test_folder/file1.txt test_folder/file2.txt
dir_name="test_folder"
rm -r "$dir_name"
