PREZIP-BIN(1)                     Aspell Abbreviated User's Manual                     PREZIP-BIN(1)



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

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

DESCRIPTION
       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.

COMMANDS
       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.

EXAMPLES
       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.

TIPS
       Prezip-bin  is  best used with sorted word list type files.  It is not a general purpose com‐
       pression 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  for‐
       matting 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.

DIAGNOSTICS
       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 ad‐
              vanced format.  The output file will be empty.

       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 out‐
              put, 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.
