How does the -i option prevent accidental data loss?

The -i option (or --interactive) in the cp command prevents accidental data loss by prompting the user for confirmation before overwriting an existing file at the destination.

How It Works:

Prompt for Confirmation: When you attempt to copy a file to a destination where a file with the same name already exists, the -i option triggers a prompt asking if you want to overwrite the existing file.
User Decision: The user can choose to proceed with the overwrite by responding with y (yes) or cancel the operation by responding with n (no).
Avoids Unintentional Overwrites: This interactive step ensures that users are aware of the potential loss of data in the destination file, allowing them to make an informed decision.

Example:

cp -i source_file.txt destination_file.txt

If destination_file.txt exists, the prompt will appear:

cp: overwrite 'destination_file.txt'?

This gives the user a chance to reconsider before proceeding.
