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.
