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.
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.
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.

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.
