Sample service script for debianoids

Look at LSB init scripts for more information.

Usage

Copy to /etc/init.d:

# replace "$YOUR_SERVICE_NAME" with your service's name (whenever it's not enough obvious)

#!/bin/bash
# This script will install a Git pre-push hook that prevents force pushing the master/main branch.
# There are three variants that I have built:
# - pre-push: prevents force-pushing to master/main.
# - pre-push-2: prevents force-pushing to master/main depending on the remote (you need to edit the file!).
# - pre-push-3: prevents any type of pushing to master/main.
# Set the desired version like this before proceeding:
# FILE=pre-push

# Single repo installation:
