NAME
     dd -- convert and copy a file

SYNOPSIS
     dd [operands ...]

DESCRIPTION
     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.
