In This Scenario will create a local repository and set up the git hook.
Let’s start by setting up the repo locally

#!/bin/bash
mkdir ~/my-repo
cd ~/my-repo
git init
git status
touch test.txt
git add test.txt
git commit -m "First commit"
git branch
git checkout -b feature-1 #Optionally
git checkout master #Optionally to switch back to the master branch

use your preferred editor and add the above command, save it as my-local-repo-initialization.sh and then run it

sh my-local-repo-initialization.sh

Okay after we have successfully created and initiated our local repo, we can know use the prepare-commit-msg hook bash script below to add our custom commit message.

add the below commands to the ~/my-repo/.git/hooks/prepare-commit-msg

#!/bin/bash
FILE=$1
COMMIT_MESSAGE=$(cat $FILE)
CUSTOME_MESSAGE="bug-fix" ### you can change the bug-fix to your customised message 

echo "$CUSTOME_MESSAGE $COMMIT_MESSAGE" > $FILE

after you have added the above now we need to make it as a executable file so that git run it whenever there are new commits.

chmod +x ~/my-repo/.git/hooks/prepare-commit-msg

Okay. now we are good to test the prepare-commit-msg hook

git log
git status
echo "first line" > test.txt
git status
git add test.txt
git commit -m "Adding First Line"
git log
