dd uses the options ________to carve out a portion of data blocks from a source.
The dd command uses the options if (input file) and of (output file) to carve out a portion of data blocks from a source. Additionally, the bs (block size) option can be used to specify the size of the blocks being read and written, and the count option can be used to specify the number of blocks to copy.
For example, a command might look like this:
dd if=/dev/sda of=/path/to/output.img bs=512 count=100
In this example, if specifies the input file (source), of specifies the output file (destination), bs sets the block size to 512 bytes, and count limits the operation to 100 blocks.
