-       dd - convert and copy a file
-SYNOPSIS
-       dd [OPERAND]...
-       dd OPTION
-DESCRIPTION
-       Copy a file, converting and formatting according to the operands.
-       bs=BYTES
-              read and write up to BYTES bytes at a time (default: 512); overrides ibs and 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 up to 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=N skip N obs-sized blocks at start of output
-skip=N skip N ibs-sized blocks at start of input
-       status=LEVEL
-              The LEVEL of information to print to stderr; 'none' suppresses everything but error messages, 'noxfer' suppresses the final transfer statistics, 'progress' shows periodic transfer statistics
-       N and BYTES may be followed by the following multiplicative suffixes: 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.
-       Each CONV symbol may be:
-       ascii  from EBCDIC to ASCII
-       ebcdic from ASCII to EBCDIC
-       ibm    from ASCII to alternate EBCDIC
-       block  pad newline-terminated records with spaces to cbs-size
-       unblock
-              replace trailing spaces in cbs-size records with newline
-       lcase  change upper case to lower case
-       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
-       sync   pad every input block with NULs to ibs-size; when used with block or unblock, pad with spaces rather than NULs
-       excl   fail if the output file already exists
-       nocreat
-              do not create the output file
-       notrunc
-              do not truncate the output file
-       noerror
-              continue after read errors
-       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 suggested)
-       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
-       nocache
-              Request to drop cache.  See also oflag=sync
-       noctty do not assign controlling terminal from file
-       nofollow
-              do not follow symlinks
-       count_bytes
-              treat 'count=N' as a byte count (iflag only)
-       skip_bytes
-              treat 'skip=N' as a byte count (iflag only)
-       seek_bytes
-              treat 'seek=N' as a byte count (oflag only)
-       Sending a USR1 signal to a running 'dd' process makes it print I/O statistics to standard error and then resume copying.
-       Options are:
-       --help display this help and exit
-       --version
-              output version information and exit
