Introduction Data security is a critical concern, especially when dealing with sensitive information. Simply deleting a file or formatting a disk does not guarantee that the data is permanently erased. To securely wipe data in Linux, the shred and dd commands are powerful tools that help prevent data recovery. In this guide, we will explore how to use the shred and dd commands effectively, provide practical examples, and answer common questions regarding secure data deletion. How Does Data Deletion Work in Linux? Before diving into the commands, it's important to understand how data deletion works in Linux: Deleting a file only removes its reference from the file system; the actual data remains on the disk until overwritten. Formatting a drive may erase file structures, but data can still be recovered with specialized tools. Secure deletion involves overwriting data multiple times to ensure it cannot be retrieved. This is where the shred and dd commands become useful. Usin...
