With the sample input files you provided, why is there only one line of output? Why shouldn't the output from those two input files be:
?
Note that the join command:
produces the output above from your sample input, but you ignored my note about preprocessing both input files to produce a single key field. The above command only compares the hash fields in the two files and completely ignores the salt fields when looking for matches in the two input files.
If the above output is acceptable but you need to match both the hash and salt fields, you might try using awk:
which also produces the output shown above from your sample input files.
If someone else wants to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk or nawk.

PNGNQ(1) User Manuals PNGNQ(1)NAME
pngnq - quantize png images
SYNOPSIS
pngnq [-vfhV][-s sample_factor ][-Q dither ][-g gamma ][-e extension ][-d dir ][-n colors ][ inputfiles ]
DESCRIPTION
pngnq Quantizes a 32-bit RGBA PNG image to an 8 bit RGBA palette PNG using the neuquant algorithm. The output file name is the input file
name extended with "-nq8.png" or a specified extension.
OPTIONS -v Verbose mode. Prints status messages.
-f Force ovewriting of files.
-s sample factor
Sample factor. The neuquant algorithm samples pixels stepping by this value. The default value of 3 gives good results. Higher val-
ues sample less of the image pixels and thus are faster but less accurate. A factor of 1 samples every image pixel.
-n colors
Specifies the number of colors to quantize to. Defaults to 256 which is the maximum. The minimum here is 2.
-Q dither
Choose a dithering method: n = no dither (default), f = Floyd Steinberg dithering.
-g gamma
Set the image gamma correction. If not present, uses the png file's gamma or defaults to 1.0.
-e extension
Specifies the new filename extension. Defaults to "-nq8.png". Pngnq drops .png from the original filenames. If you set the argument
of the -e option to .png and choose the -f option the input file will be overwritten.
-d dir Tells pngnq to put output files in a directory other than the one the input files are in.
input files
The png files to be processed. Defaults to standard input if not specified. If standard input is being processed the output is sent
to standard output.
-h Print program help.
-V Print version number and library versions.
BUGS
Does not deal correctly with greyscale alpha images with low bit depths, but these wont benefit from quantizing.
