prepare-commit-msg

#!/bin/bash

# Get the current branch name
current_branch=`git rev-parse --abbrev-ref HEAD`

# Search Jira ID in a pattern such a "feature/ABCD-123-my-feature"
id=$(echo $current_branch | sed -nE 's,[a-z]+/([A-Z]+-[0-9]+)-.+,\1,p')

# only prepare commit message if pattern matched and jiraId was found
if [[ ! -z $id ]]; then
 # $1 is the name of the file containing the commit message
 # Prepend "ABCD-123: "
 sed -i.bak -E "1s/^/${id}: /" $1
