Command:   dd - disk dumper
Syntax:    dd [option = value] ...
Flags:     (none)
Examples:  dd if=/dev/fd0 of=/dev/fd1 # Copy disk 0 to disk 1
           dd if=x of=y bs=1w skip=4 # Copy x to y, skipping 4 words
           dd if=x of=y count=3     # Copy three 512-byte blocks

     This command is intended for  copying  partial  files.   The  block
size,  skip  count,  and number of blocks to copy can be specified.  The
options are:

   if = file      - Input file (default is stdin)
   of = file      - Output file (default is standard output)
   ibs = n        - Input block size (default 512 bytes)
   obs = n        - Output block size (default is 512 bytes)
   bs = n         - Block size; sets ibs and obs (default is 512 bytes)
   skip = n       - Skip n input blocks before reading
   seek = n       - Skip n output blocks before writing
   count = n      - Copy only n input blocks
   conv = lcase   - Convert upper case letters to lower case
   conv = ucase   - Convert lower case letters to upper case
   conv = swab    - Swap every pair of bytes
   conv = noerror - Ignore errors and just keep going
   conv = silent  - Suppress statistics (Minix specific flag)

Where sizes are expected, they are in bytes.  However, the letters w, b,
or  k  may be appended to the number to indicate words (2 bytes), blocks
(512 bytes), or K (1024 bytes), respectively.  When dd is  finished,  it
reports the number of full and partial blocks read and written.
