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.
