NAME
       dcfldd   manual page for dcfldd (dcfldd) 1.3.4

SYNOPSIS
       dcfldd [OPTION]...

DESCRIPTION
       Copy a file, converting and formatting according to the options.

       bs=BYTES
              force ibs=BYTES and obs=BYTES

       cbs=BYTES
              convert BYTES bytes at a time

       conv=KEYWORDS
              convert the file as per the comma separated keyword list

       count=BLOCKS
              copy only BLOCKS input blocks

       ibs=BYTES
              read BYTES bytes at a time

       if=FILE
              read from FILE instead of stdin

       obs=BYTES
              write BYTES bytes at a time

       of=FILE
              write to FILE instead of stdout

              NOTE: of=FILE may be used several times to write

              output to multiple files simultaneously

       of:=COMMAND
              exec and write output to process COMMAND

       seek=BLOCKS
              skip BLOCKS obs sized blocks at start of output

       skip=BLOCKS
              skip BLOCKS ibs sized blocks at start of input

       pattern=HEX
              use the specified binary pattern as input

       textpattern=TEXT
              use repeating TEXT as input

       errlog=FILE
              send error messages to FILE as well as stderr

       hashwindow=BYTES
              perform a hash on every BYTES amount of data

       hash=NAME
              either md5, sha1, sha256, sha384 or sha512

              default algorithm is md5. To select multiple algorithms to run simultaneously enter the names in a comma separated list

       hashlog=FILE
              send MD5 hash output to FILE instead of stderr

              if  you  are  using  multiple  hash  algorithms you can send each to a seperate file using the convention ALGORITHMlog=FILE, for example md5log=FILE1,
              sha1log=FILE2, etc.

       hashlog:=COMMAND
              exec and write hashlog to process COMMAND

              ALGORITHMlog:=COMMAND also works in the same fashion

       hashconv=[before|after]
              perform the hashing before or after the conversions

       hashformat=FORMAT
              display each hashwindow according to FORMAT

              the hash format mini language is described below

       totalhashformat=FORMAT
              display the total hash value according to FORMAT

       status=[on|off]
              display a continual status message on stderr

              default state is "on"

       statusinterval=N
              update the status message every N blocks

              default value is 256

       sizeprobe=[if|of]
              determine the size of the input or output file

              for use with status messages. (this option gives you a percentage indicator) WARNING: do not use this option against a

              tape device.

       split=BYTES
              write every BYTES amount of data to a new file

              This operation applies to any of=FILE that follows

       splitformat=TEXT
              the file extension format for split operation.

              you may use any number of 'a' or 'n' in any combo the default format is "nnn" NOTE: The split and splitformat options take effect

              only for output files specified AFTER these options appear in the command line.  Likewise, you may specify these several times for for different  out 
              put  files  within the same command line. you may use as many digits in any combination you would like.  (e.g. "anaannnaana" would be valid, but quite
              insane)

       vf=FILE
              verify that FILE matches the specified input

       verifylog=FILE
              send verify results to FILE instead of stderr

       verifylog:=COMMAND
              exec and write verify results to process COMMAND

         help display this help and exit

         version
              output version information and exit

       The structure of of FORMAT may contain any valid text and special variables.  The built in variables are used the following format:
