dd about ff4d HOT 1 CLOSED

...
     The dd utility copies the standard input to the standard output.  Input
     data is read and written in 512-byte blocks.  If input reads are short,
     input from multiple reads are aggregated to form the output block.  When
     finished, dd displays the number of complete and partial input and output
     blocks and truncated input records to the standard error output.

     of=file  Write output to file instead of the standard output.  Any regu-
              lar output file is truncated unless the notrunc conversion value
              is specified.  If an initial portion of the output file is
              seeked past (see the oseek operand), the output file is trun-
              cated at that point.
