Hello H squared,

Could you please try following and let me know if this helps you.
Code:
awk 'FNR==NR{A[$1]=$1;next} ($1 in A){print $1 >> "similar_ones.txt";delete A[$1];next} !($1 in A){print $1 >> "dissimilar_ones.txt"} END{for(i in A){print A[i] >> "dissimilar_ones.txt"}}'  Input_file1   Input_file2

Above will create 2 files named similar_ones.txt and dissimilar_ones.txt, which will be as follows.
Code:
cat similar_ones.txt
1
3
8

cat dissimilar_ones.txt
x
z
m
0
4
6
f
2
g

EDIT: Adding a non-one liner form of solution now.
Code:
awk 'FNR==NR{
             A[$1]=$1;
             next
            }
     ($1 in A){
                print $1 >> "similar_ones.txt";
                delete A[$1];
                next
              }
     !($1 in A){
                print $1 >> "dissimilar_ones.txt"
               }
     END{
                for(i in A){
                                print A[i] >> "dissimilar_ones.txt"
                           }
        }
    '  Input_file1   Input_file2

NOTE: File dissimilar_ones.txt will have difference of both the files, means: will have contents which are in Input_file1 and NOT in Input_file2
+ will have contents which are in Input_file2 and NOT in Input_file1.

Thanks,
R. Singh

ppmtosixel

ppmtosixel(1)                                                 General Commands Manual                                                ppmtosixel(1)

NAME

       ppmtosixel - convert a portable pixmap into DEC sixel format

SYNOPSIS

       ppmtosixel [-raw] [-margin] [ppmfile]

DESCRIPTION

       Reads  a  portable  pixmap  as input.  Produces sixel commands (SIX) as output.  The output is formatted for color printing, e.g. for a DEC
       LJ250 color inkjet printer.

       If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled.  A printer control header and a color assignment table
       begin the SIX file.  Image data is written in a compressed format by default.  A printer control footer ends the image file.

OPTIONS

       -raw   If  specified,  each  pixel  will  be explicitly described in the image file.  If -raw is not specified, output will default to com-
              pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands.  A raw file is often an order  of  magni-
              tude larger than a compressed file and prints much slower.

       -margin
              If  -margin  is not specified, the image will be start at the left margin (of the window, paper, or whatever).  If -margin is speci-
              fied, a 1.5 inch left margin will offset the image.

PRINTING

       Generally, sixel files must reach the printer unfiltered.  Use the lpr -x option or cat filename > /dev/tty0?.

BUGS

       Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion.  If the original PPM maxval was
       greater  than  100,  rescaling  also reduces the image depth.  While the actual RGB values from the ppm file are more or less retained, the
       color palette of the LJ250 may not match the colors on your screen.  This seems to be a printer limitation.
