The dd command is a versatile and powerful utility used for data copying and conversion in Unix-like operating systems.
It is commonly used for creating backups, disk imaging, cloning drives, and performing low-level data operations.
Key features include specifying input and output sources, block sizes, and support for various data formats.
For example, running dd if=/dev/sda of=/path/to/backup.img bs=4M creates a disk image backup of a drive and saves it to a file using a block size of 4 megabytes.
The dd command is a flexible tool with various applications in data manipulation and storage management.
