The command "sfill -I ${-path-to-mounted_disk_directory}" is used to securely fill a specific directory on a mounted disk with random data. Here is the breakdown of the command:

• "sfill": It is a command-line utility used for securely wiping the contents of files and disk space.
• "-I": It is an option/flag used with the "sfill" command to specify the directory to be filled with random data.
• "${-path-to-mounted_disk_directory}": This is a placeholder for the actual path to the directory on the mounted disk. You need to replace it with the real path (e.g., /mnt/disk1).

By running this command, the designated directory on the mounted disk will be filled with random data. This process is used to overwrite the existing data and make it much harder for anyone to recover any sensitive information from the disk.
