Be careful when using the rm command, as it will permanently delete the specified file or directory without confirmation.

The permissions are represented by three digits, each of which corresponds to a specific set of permissions:

• The first digit represents the owner’s permissions
• The second digit represents the group’s permissions

Each digit can be a combination of three values:
