There appears to be a misunderstanding
Maybe. If only you would give an example of the expected output...
On the other hand, Magic Banana's script is looking at only one of the two
files
No, it is not. I do not write scripts taking several files in arguments to
only use one.
I've tried to save the scripts as MB.suggestion02.txt & MB.suggestion03.txt,
cp them to *.bin and *.sh, respectively
The execution will be the same, whatever the name you give to the script.
Indeed, for GNU/Linux systems, extensions do not "exist". Only whole file
names do. Now, for users, if there is an extension, it is supposed to
indicate the file format: users expect .jpg files to be images and not
sounds, for instance. In the same way, .bin files are expected to be
binaries and .sh files are expected to be shell scripts. Shell scripts are
not binaries. They are plain text files.
./mb.suggestion02.bin filename01 - or ./MB.suggestion03.sh filename02 -
Again: - is the standard input. If you do not redirect it (apparently the
case here), it is the keyboard: the script is here expecting you to type the
second file.
I do not know how to be clearer on how to call the script: a help message
specifies the usage and I gave you an example of a call (using the files you
attached) at the end of

Directly write the script in a file bearing the name you want to execute it.
chmod +x MB.suggestion02.bin and chmod +x Mb.suggestion03.sh before lastly
executing them with ./mb.suggestion02.bin filename01 - or
./MB.suggestion03.sh filename02 -
The error messages repeatedly say for either combination of filenames:
bash: ./MBsuggestion03.sh: No such file or directory or ./MBsuggestion02.bin:
No such file or directory
The error messages say neither "./MBsuggestion02.bin" nor
"./MBsuggestion03.sh" exist. But if you would have really executed the
command you wrote immediately before, the messages would be about
"./mb.suggestion02.bin" and "./MB.suggestion03.sh". You would get the same
error message if you named the scripts "MB.suggestion02.bin" and
"Mb.suggestion03.sh", as the previous sentence suggests.
If you cannot type a same file name twice, you will never manage to execute
any script. The letter case matters. And no character can be skipped.
Fortunately, auto-completion makes it easy to correctly and efficiently input
file names: you should use it.
And, I repeat: you want a meaningful name for the script (pick only one,
depending on whether you want the default value for the output directory). I
proposed "join-and-group-by-ptr" at the end of
https://trisquel.info/forum/find-instances-each-list-strings-and-print-each-set-separate-file#comment-150667
No new directories appear.
With two arguments, the script in
https://trisquel.info/forum/find-instances-each-list-strings-and-print-each-set-separate-file#comment-150649
displays the help message (because it requires three arguments) and the one
in
https://trisquel.info/forum/find-instances-each-list-strings-and-print-each-set-separate-file#comment-150667
would write files in the working directory (the default I chose if the third
argument is missing).
In my alternative scripting, I created the two necessary directories
beforehand.
Two directories? Your original post gave a command line with one single
output and you wrote that "each group [of IPv4 addresses] needs to be
diverted to a separate filename with ".txt" appended to the unique PTR".
How does that make two directories?
