#!/bin/bash
# Rebase latest remote base branch when you are working on a feature branch
# + delete merged remote branches
#
# `git rbb` is a abbreviation of `git ReBase Base branch` :-)
#
# This will...
# 1. Commit current changes temporarily if there are uncommitted changes
# 2. Pull base branch with '--prune' option without checkout
# 3. Rebase develop
# 4. Reset temporary commit to restore
#
# Instruction
# 1. Move this file to ~/.gitsh/
# 2. Add directory path($YOUR_HOME_PATH/.gitsh) to environment variable file
#    (like ~/.bash_profile or ~/.zshrc)
#    (This would be like 'export PATH=${PATH}:/Users/YOUR_HOME_PATH/.gitsh'
# 3. chmod 0755 git-rbb
# 4. Use the command 'git rbb BASE_BRANCH'
