How can I erase all data on Ubuntu?

To clear all data, you can follow these steps:

1. Open the terminal window (Ctrl + Alt + T).
2. Enter the following command to delete all files and folders:

sudo rm -rf /

This command will delete all files and folders, including system files, so please proceed with caution.

1. The system will prompt you to enter the administrator password to confirm the deletion operation. Please enter the password and press the enter key.
2. Wait for the command execution to be completed, and the system will clear all data and restart.

Please note that this operation is very risky as it will delete all data, including your personal and system files, potentially causing the system to malfunction. Please backup important data before proceeding with this operation.
