This document provides numerous examples of Git aliases that can help streamline workflows. It begins by demonstrating aliases for common commands like status, last commit, checkout, add, commit, reset, and grep. It then shows more advanced aliases for managing branches, commits, and reflogs. Throughout, it emphasizes that aliases can make workflows more efficient by avoiding repetitive tasks and that teams should consider sharing standardized aliases. It concludes by encouraging readers to continually learn Git, customize workflows for their needs, and view themselves as craftspeople improving their skills.

- 1. 1 Git on the front line Nicola Iarocci
- 2. 2 Who Am INicola Iarocci, a weirdo Python by Night I am the author and maintainer of a few Python open source projects: python-eve.org, python-cerberus.organd more. Microsoft MVP MongoDB Master I also happen to be a Microsoft MVP for Visual Studio and Development Technologies and a MongoDB Master.

- 3. 3 one size does not fit all git workflows
- 4. 4 the main branch where the source code of HEAD always reflects a production-ready state origin/master main branch where HEAD always holds the latest delivered development changes, ready for next release origin/develop feature, release and hotfix branches. these always have a limited life time, since they will be removed eventually supporting branches an elegant mental model well suited for packaged software. Not ideal for frequent release cycles such as those we have in modern web development summary Git Flowa successful git branching model http://nvie.com/posts/a-successful-git-branching-model/
- 5. 5 the main branch where the source code of HEAD always reflects a production-ready state origin/master to work on something new, create a descriptively named branch off of master branch feature branch when you need feedback or help, or you think the branch is ready for merging, open a pull request pull request & review a lightweight, branch-based workflow that supports teams and projects where deployments are made regularly summary GitHub Flowwidely adopted by the open source community http://scottchacon.com/2011/08/31/github-flow.html
