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.:
