Oh, BTW (re: 'Struggling with mkfifo')
Just in case you're wondering why I am bothering with MKFIFO, MKNOD etc... is for the following reason:
I want to uncompress/compress a database binary (export) file and import/export the output into difference instances of my database simultaneously. I know that this can be done using a "named pipe" alongside with un/compress being run in the background.
That's what I am trying to accomplish. FYI.

word-list-compress
WORD-LIST-COMPRESS(1) Aspell Abbreviated User's Manual WORD-LIST-COMPRESS(1)
NAME
word-list-compress - word list compressor/decompressor for GNU Aspell
SYNOPSIS
word-list-compress c[ompress] | d[ecompress]
DESCRIPTION
word-list-compress compresses or decompresses sorted word lists for use with the GNU Aspell spell checker.
COMMANDS
-c, c, compress
compress the plain text word list read from standard input.
-d, d, decompress
decompress the compressed word list read from standard input.
EXAMPLES
Here are a few examples of how you can use word-list-compress
word-list-compress d <wordlist.cwl >wordlist.txt
Decompress file wordlist.cwl to text file wordlist.txt
word-list-compress c <wordlist.wl >wordlist.cwl 2>errors.txt
Compress wordlist.wl to wordlist.cwl and send any error messages to a text file named errors.txt
LC_COLLATE=C sort -u <wordlist.txt | word-list-compress c >wordlist.cwl
Sort a word list, then pipe it to word-list-compress to create a compressed binary wordlist.cwl file.
word-list-compress d <words.cwl | 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
Word-list-compress is best used with sorted word list type files. It is not a general purpose compression program since the resulting
files may actually increase in size.
Word-list-compress accepts up to 255 text characters in the range of {0x21...0xFF}. If your word list requires a larger character set for
certain languages or longer length for multi-word, scientific, medical, technical or other use, then it is recommended that you compress
your word list using prezip-bin(1)
DIAGNOSTICS
Word-list-compress normally exits with a return code of 0. If it encounters an error, a message is sent to standard error output (stderr),
and word-list-compress exits with a non-zero return value. Error messages are listed below:
(display help/usage message)
Unknown command given on the command line so word-list-compress displays a usage message to standard error output.
Corrupt Input
This is only for the decompression command d. The input file is of an unknown format or the input file/stream is corrupted. You
may have some valid output, but word-list-compress could not complete the process. If the input file is a compressed wordlist but
you have no output file, then it may be a newer prezip-bin(1) version of compressed file, if so, try decompressing the file with
prezip-bin(1) instead.
Output Data Error
The output is full, write protected, or has an error and can no longer be written to.
