PREZIP-BIN(1)          Aspell Abbreviated User's Manual          PREZIP-BIN(1)

       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 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.

       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 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.
