    SYNOPSIS

           dd [OPERAND]...
           dd OPTION
    
    
    

    DESCRIPTION

           Copy a file, converting and formatting according to the operands.
    
           bs=BYTES
                  read and write BYTES bytes at a time (also see ibs=,obs=)
    
           cbs=BYTES
                  convert BYTES bytes at a time
    
           conv=CONVS
                  convert the file as per the comma separated symbol list
    
           count=N
                  copy only N input blocks
    
           ibs=BYTES
                  read BYTES bytes at a time (default: 512)
    
           if=FILE
                  read from FILE instead of stdin
    
           iflag=FLAGS
                  read as per the comma separated symbol list
    
           obs=BYTES
                  write BYTES bytes at a time (default: 512)
    
           of=FILE
                  write to FILE instead of stdout
    
           oflag=FLAGS
                  write as per the comma separated symbol list
    
           seek=BLOCKS
                  skip BLOCKS obs-sized blocks at start of output
    
           skip=BLOCKS
                  skip BLOCKS ibs-sized blocks at start of input
    
           status=WHICH
                  WHICH info to suppress outputting to stderr; 'noxfer' suppresses
                  transfer stats, 'none' suppresses all
    
           BLOCKS and BYTES may be followed by the following  multiplicative  suf-
           fixes:  c  =1,  w  =2,  b  =512,  kB  =1000,  K =1024, MB =1000*1000, M
           =1024*1024, xM =M GB =1000*1000*1000, G =1024*1024*1024, and so on  for
           T, P, E, Z, Y.
    
    
           nocreat
                  do not create the output file
    
           excl   fail if the output file already exists
    
           notrunc
                  do not truncate the output file
    
           ucase  change lower case to upper case
    
           sparse try to seek rather than write the output for NUL input blocks
    
           swab   swap every pair of input bytes
    
           noerror
                  continue after read errors
    
           sync   pad  every  input  block  with  NULs to ibs-size; when used with
                  block or unblock, pad with spaces rather than NULs
    
           fdatasync
                  physically write output file data before finishing
    
           fsync  likewise, but also write metadata
    
           Each FLAG symbol may be:
    
           append append mode (makes sense  only  for  output;  conv=notrunc  sug-
                  gested)
    
           direct use direct I/O for data
    
           directory
                  fail unless a directory
    
           dsync  use synchronized I/O for data
    
           sync   likewise, but also for metadata
    
           fullblock
                  accumulate full blocks of input (iflag only)
    
           nonblock
                  use non-blocking I/O
    
           noatime
                  do not update access time
    
           noctty do not assign controlling terminal from file
    
           nofollow
           Options are:
    
           --help display this help and exit
    
           --version
                  output version information and exit
