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
       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 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 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.
