PREZIP(1) Aspell Abbreviated User's Manual PREZIP(1)NAME
prezip, preunzip, precat - prefix delta compressor for Aspell
SYNOPSIS
precat [-dzhLV] [-cfksSq] [file ...]
DESCRIPTION
prezip is a a prefix delta compressor. It is not a general purpose compressor and should only be used on sorted word lists or other simi-
lar text files. It will likely increase the size of binary data.
If invoked as prezip, the default action is to compress. If invoked as preunzip, the default action is to decompress. If invoked as pre-
cat, the default action is to decompress to stdout.
If no file names are given then prezip will compress or decompress from the standard input to the standard output. Short flags can be com-
bined so that "-c -s" is the same as "-cs".
OPTIONS -h --help

-d --decompress

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 actu-
ally 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.
