bionic (1) prezip-bin.1.gz

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.
