9 prezip-bin [ -V | -d | -z ]
10
12 prezip-bin compresses/decompresses sorted word lists from standard
13 input to standard output.
14 Prezip-bin is similar to word-list-compress(1) but it allows a larger
16 character set of {0x00...0x09, 0x0B, 0x0C, 0x0E...0xFF} and multi-words
17 larger than 255 characters in length. It can also decompress
18 word-list-compress(1) compatible files.
19
21 Prezip-bin accepts only one of these commands.
22 -V Display prezip-bin version number to standard output.
24 -d Read a compressed word list from standard input and decompress
26 it to standard output. This can be a word-list-compress(1) or a
27 prezip-bin compressed file.
28 -z Read a binary word list from standard input and compress it to
30 standard output.
31
33 prezip-bin -d <wordlist.cwl >wordlist.txt
34 Decompress file wordlist.cwl to text file wordlist.txt
35 prezip-bin -z <wordlist.txt >wordlist.pz 2>errors.txt
37 Compress wordlist.txt to binary file wordlist.pz and send any
38 error messages to a text file named errors.txt
39 LC_COLLATE=C sort -u <wordlist.txt | prezip-bin -z >wordlist.pz
41 Sort a word list, then pipe it to prezip-bin to create a com‐
42 pressed binary wordlist.pz file.
43 prezip-bin -d <words.pz | aspell create master ./words.rws
45 Decompress a wordlist, then pipe it to aspell(1) to create a
46 spelling list. Please check the aspell(1) info manual for
47 proper usage and options.

50 Prezip-bin is best used with sorted word list type files. It is not a
51 general purpose compression program since resulting files may actually
52 increase in size.
53 Unlike word-list-compress(1) if your word list has leading or trailing
55 blank spaces for formatting purposes, you should remove them first
56 before you compress your list using prezip-bin -z , otherwise those
57 spaces will be included in the compressed binary output.
58
60 Prezip-bin normally exits with a return code of 0. If it encounters an
61 error, a message is sent to standard error output (stderr), and
62 prezip-bin exits with a non-zero return value. Error messages are
63 listed below:
64 (display help/usage message)
66 Unknown command given on the command line so prezip-bin displays
67 a usage message to standard error output.
68 unknown format
70 The input file appears not to be an expected format, or may pos‐
71 sibly be a more advanced format. The output file will be empty.
72 corrupt input
74 This is only for the decompression command -d. The input file
75 appeared to be of a correct format, but something appears wrong
76 now. There may be some valid data in output, but due to input
77 corruption, the rest of the file can not be completed.
78 unexpected EOF
80 The input file appeared okay but ended sooner than expected,
81 therefore the output file is not complete.
