Git bulk rebase

Use case

When you have multiple branches need to rebase with same a branch. You need to switch to each branch and rebase it. This script help you to automate switch and rebase with each branch with main branch (auto get or you can passing it into first argument)

Usage

./git-bulk-rebase.sh <main branch>

git-bulk-rebase.sh

#!/usr/bin/env bash

main_branch="$1"
RED="\033[1;31m"
GREEN="\033[1;32m"
NC="\033[0m"

if [ -z "$main_branch" ];then
  main_branch=$(git branch | cut -c 3- | grep -E "^milestone_")
fi

function bulk_rebase() {
  for branch in $(git branch | cut -c 3-); do
    if [[ ! "$branch" =~ ^(milestone_|develop) ]]; then
      echo -en "Do you want to rebase branch [${GREEN}${branch}${NC}] with branch [${RED}${main_branch}${NC}] (y/n/q)?: "
      read answer

      if [[ "$answer" =~ q|Q ]]; then
        break
      elif  [[ "$answer" =~ y|Y ]]; then
        (git checkout "$branch" && git rebase "$main_branch")

        if [ $? -ne "0" ]; then
          echo "Error when rebase [${GREEN}${branch}${NC}] with [${RED}${main_branch}${NC}]. Please check it!"
