prezip-bin - prefix zip delta word list compressor/decompressor
prezip-bin [
-V |
-d |
-z ]
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.
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.
- 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.
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.
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.
