Script to compare 2 files line by line

Question

I have two text files:

File1.txt

dadads 434 43 {"4fsdf":"66db1" fdf1:"5834"}
gsgss 45 0 {"gsdg":"8853" sgdfg:"4631"}
fdf 767 4643 {"klhf":"3455" kgs:"4566"}
.  
.

File2.txt

8853
6437437567
36265
4566
.
.

Output could be two files

Match.txt

gsgss 45 0 {"gsdg":"8853" sgdfg:"4631"}
fdf 767 4643 {"klhf":"3455" kgs:"4566"}

Non_Match.txt

dadads 434 43 {"4fsdf":"66db1" fdf1:"5834"}

Can someone help me write bash script for this?

I think i have the logic here if it helps:

 for (rows in File1.txt) {
   bool found = false;
    for (id in File2.txt) {
      if (row contains id) {
      found = true;
      echo row >> Match.txt
      break;
     }
    }
   if (!found) {
      echo row >> Non_Match.txt
   }
  }

Edit Part:

I also have a bash script but its not helping as it is not putting the row which matches but instead only the ID that matches..

#!/bin/bash

set -e

file1="File2.txt"
file2="File1.txt"

for id in $(tail -n+1 "${file1}"); do
   if ! grep "${id}" "${file2}"; then
      echo "${id}" >>non_matches.txt
   else
       echo "${id}" >>matches.txt
   fi
done

You could use grep -f to look for search patterns that are listed in a separate file. It'd probably be good to use the -F (fixed strings) and -w (match whole words) flags as well.

grep -Fw  -f File2.txt File1.txt > Match.txt
grep -Fwv -f File2.txt File1.txt > Non_Match.txt
