Hi, thanks for your code. Anyway I found a small bug in hexTorgb.awk:
printf("rgb(%d,%d,%d)\n",rgb[1], rgb[2], rgb[3])should be
printf( "%d,%d,%d", strtonum( rgb[1] ), strtonum( rgb[2] ), strtonum( rgb[3] ) )unless awk will not recognise rgb[i] as a number but as a string and it will always print 0,0,0.
