PREZIP-BIN(1) Aspell Abbreviated User's Manual PREZIP-BIN(1)

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.
