The command sfill -i ${-path-to-mounted_disk_directory} is used to securely fill the free space on a disk partition with random data.

Here's a breakdown of the command:

• sfill: It is a command-line utility in Linux designed to securely erase the free space on a disk partition by overwriting it with random data.
• -i: It is an option that tells sfill to work in interactive mode, which means it will prompt for confirmation before proceeding.
• ${-path-to-mounted_disk_directory}: This is a placeholder for the actual path to the directory of the mounted disk partition you want to securely fill. You need to replace ${-path-to-mounted_disk_directory} with the appropriate path to the directory.

Make sure to replace ${-path-to-mounted_disk_directory} with the correct path before executing the command.
