cfdisk: Create a new partition table for a specific device and manage it.
$ cfdisk --zero ${-dev-sdX}
try on your machine
The command "cfdisk --zero ${-dev-sdX}" is used to erase all data on a specific storage device (identified as /dev/sdX) using the cfdisk tool.
Here's an explanation of each component:
- "cfdisk": This is the name of the command-line utility used for managing disk partitions on Linux systems.
- "--zero": This option tells cfdisk to overwrite the entire disk with zeros, effectively wiping all data from it.
- "${-dev-sdX}": This is a placeholder used to denote the actual storage device you want to wipe. Replace "sdX" with the appropriate drive letter or number, such as "sda", "sdb", or "sdc".
So, when you run this command with the correct device name, it will launch cfdisk and instruct it to zero out all data on that storage device, ensuring that any existing partitions and files are permanently deleted.
