prezip-bin - prefix zip delta word list compressor/decompressor


   prezip-bin [ -V | -d | -z ]


   prezip-bin  compresses/decompresses  sorted  word  lists  from standard
   input to standard output.

   Prezip-bin is similar to word-list-compress(1) but it allows  a  larger
   character set of {0x00...0x09, 0x0B, 0x0C, 0x0E...0xFF} and multi-words
   larger  than  255  characters  in  length.   It  can  also   decompress
   word-list-compress(1) compatible files.


   Prezip-bin accepts only one of these commands.

   -V     Display prezip-bin version number to standard output.

   -d     Read  a  compressed word list from standard input and decompress
          it to standard output.  This can be a word-list-compress(1) or a
          prezip-bin compressed file.

   -z     Read  a  binary word list from standard input and compress it to
          standard output.


   prezip-bin -d <wordlist.cwl >wordlist.txt
          Decompress file wordlist.cwl to text file wordlist.txt

   prezip-bin -z <wordlist.txt >wordlist.pz 2>errors.txt
          Compress wordlist.txt to binary file wordlist.pz  and  send  any
          error messages to a text file named errors.txt

   LC_COLLATE=C sort -u <wordlist.txt | prezip-bin -z >wordlist.pz
          Sort  a  word  list,  then  pipe  it  to  prezip-bin to create a
          compressed binary wordlist.pz file.

   prezip-bin -d <words.pz | aspell create master ./words.rws
          Decompress a wordlist, then pipe it to  aspell(1)  to  create  a
          spelling  list.   Please  check  the  aspell(1)  info manual for
          proper usage and options.


   Prezip-bin is best used with sorted word list type files.  It is not  a
   general  purpose compression program since resulting files may actually
   increase in size.

   Unlike word-list-compress(1) if your word list has leading or  trailing
   blank  spaces  for  formatting  purposes,  you should remove them first
   before you compress your list using prezip-bin  -z  ,  otherwise  those
   spaces will be included in the compressed binary output.


   Prezip-bin normally exits with a return code of 0.  If it encounters an
   error, a message  is  sent  to  standard  error  output  (stderr),  and
   prezip-bin  exits  with  a  non-zero  return value.  Error messages are
   listed below:

   (display help/usage message)
          Unknown command given on the command line so prezip-bin displays
          a usage message to standard error output.

   unknown format
          The  input  file  appears  not  to be an expected format, or may
          possibly be a more advanced format.  The  output  file  will  be

   corrupt input
          This  is  only for the decompression command -d.  The input file
          appeared to be of a correct format, but something appears  wrong
          now.   There  may be some valid data in output, but due to input
          corruption, the rest of the file can not be completed.

   unexpected EOF
          The input file appeared okay but  ended  sooner  than  expected,
          therefore the output file is not complete.
