In the dd command shown, which parameter specifies the input device or file?

• A. if
• B. of
• C. bs
• D. count

Answer: (A)

The data source for dd is specified with the if option, which points to the input device or file to read from. If you set if=/dev/sdb1 or if=input.file, dd will read data from that source. In contrast, the output destination is defined with of=, and bs= sets the block size while count limits how many blocks are processed. So for identifying which parameter specifies the input device or file, it’s the if option.
