The GNU Core Utilities or coreutils is a package of GNU software containing implementations for many of the basic tools, such as cat, ls, and rm, which are used on Unix-like operating systems.
By default, the command overwrites the file three times with multiple patterns, but the number is user configurable. It has an option to do an additional final overwrite with zeroes, which may help to hide the fact that it was used. By default, shred also shreds file slack (unused space in file allocations). For example, a 5 KB file on a file ...

badblocks is a Linux utility to check for bad sectors on a disk drive. It can create a text file with a list of these sectors that can be used with other programs, like mkfs, so that they are not used in the future and thus do not cause data corruption. It is part of the e2fsprogs project, [1] and a port is available for BSD operating systems. [2]
Computer programming portal; Linux portal; io_uring [a] (previously known as aioring) is a Linux kernel system call interface for storage device asynchronous I/O operations addressing performance issues with similar interfaces provided by functions like read()/write() or aio_read()/aio_write() etc. for operations on data accessed by file descriptors.

DBAN can be configured to automatically wipe every hard disk that it sees on a system or entire network of systems, making it very useful for unattended data destruction ...
However, the Linux test environment automatically removed the HPA on the test drive, allowing the tool to image sectors hidden by an HPA. The tool did not acquire sectors hidden by a DCO."
