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 er-
ror 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 com-
pressed 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 be-
fore 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 pos-
sibly 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.
