[_PREZIP-BIN_(1)](https://www.chedong.com/phpMan.php/man/PREZIP-BIN/1/markdown)                     Aspell Abbreviated User's Manual                     [_PREZIP-BIN_(1)](https://www.chedong.com/phpMan.php/man/PREZIP-BIN/1/markdown)

## 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)](https://www.chedong.com/phpMan.php/man/word-list-compress/1/markdown)_  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)](https://www.chedong.com/phpMan.php/man/word-list-compress/1/markdown)_ compatible files.

## COMMANDS
       _Prezip-bin_ accepts only one of these commands.

### -V     

### -d     
              This can be a [_word-list-compress(1)](https://www.chedong.com/phpMan.php/man/word-list-compress/1/markdown)_ or a _prezip-bin_ compressed file.

### -z     

## 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)](https://www.chedong.com/phpMan.php/man/aspell/1/markdown)_ to create a  spelling  list.   Please
              check the [_aspell(1)](https://www.chedong.com/phpMan.php/man/aspell/1/markdown)_ 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)](https://www.chedong.com/phpMan.php/man/word-list-compress/1/markdown)_ 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.
