Sorry, impossible. Inside awk, TXT and XML are uninitialized variables, thus empty, and can't be used neither as a index into an array nor as a reasonable assignment value. Plus, with the leading $-sign, their contents will be interpreted as a field identifier and MUST be numeric. Again, leading nowhere.
Outside, they are just filenames, aren't they, so nothing to replace anything?

Why would I post it and say it works if it doesn't?
Not sure...?

For your original question, place a print just before and just after the replacement statements to see the difference.

NAME
ppmtopgm - convert a portable pixmap into a portable graymap SYNOPSIS
ppmtopgm [ppmfile] DESCRIPTION
Reads a portable pixmap as input. Produces a portable graymap as output. The output is a "black and white" rendering of the original image, as in a black and white photograph. The quantization formula used is .299 r + .587 g + .114 b. Note that although there is a pgmtoppm program, it is not necessary for simple conversions from pgm to ppm , because any ppm program can read pgm (and pbm ) files automatically. pgmtoppm is for colorizing a pgm file. Also, see ppmtorgb3 for a different way of converting color to gray. And ppmdist generates a grayscale image from a color image, but in a way that makes it easy to differentiate the original colors, not necessarily a way that looks like a black and white photograph. QUOTE
Cold-hearted orb that rules the night Removes the colors from our sight Red is gray, and yellow white But we decide which is right And which is a quantization error. SEE ALSO
