Colorize your diff and save the colorized output HTML for non shell users 
Required tools:
- diff
- colordiff
- Script ansi2html.sh
Install colordiff
sudo apt install colordiff
Get ansi2html.sh
wget https://github.com/lanbugs/scripts/blob/master/scripts/ansi2html.sh chmod 700 ansi2html.sh
Make a colorized diff
diff -bur core1.txt core2.txt | colordiff
You should see a colorized diff on the shell
Now let convert the ansi colored output to HTML …
diff -bur core1.txt core2.txt | colordiff | ./ansi2html.sh > /mnt/c/temp/diff.html
The ansi2html.sh script now created an HTML file which you can open in the browser now.
