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-com-
       press(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  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.

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  out-
              put.

       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 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 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.
