13 Advanced (but useful) Git Techniques and Shortcuts

TL;DR

Advanced Git techniques can make committing, correcting mistakes, debugging, and switching contexts faster and safer. The 13 tips include creating aliases, amending the latest commit, reverting pushed code, naming and restoring stashes, using bisect to find a bad commit, squashing commits with interactive rebase, and returning to the previous branch with git checkout followed by a dash. Read on for practical commands, use cases, and warnings about destructive operations.

Questions & Answers

Q: What advanced Git techniques and shortcuts can improve a developer’s workflow?

Useful techniques include aliases, amend, revert, named stashes, improved log formatting, bisect, interactive rebase, Git hooks, reset, clean, and quickly returning to the previous branch. These commands reduce repetitive work, help correct mistakes, locate bugs, consolidate history, and automate checks.

Q: How can Git aliases make common commands faster?

Git config lets you create aliases that shorten existing commands or define custom ones. For example, an alias named ac can run the add-and-commit workflow using only two letters.

Q: How do you update the latest Git commit with amend?

Use the amend flag with a new message to correct a typo in the latest commit message. You can also stage forgotten files and amend them into that commit, adding the no-edit flag when you want to keep its existing message. This is safest before pushing to a remote repository.

Q: When should you use git revert instead of force-pushing?

Use git revert after pushing a bad commit when you want to restore the previous state without deleting the original commit from history. Force-pushing overwrites the remote commit with your local state and can permanently lose remote commits that are missing locally.

Q: How do you save unfinished changes with git stash?

Run git stash to remove current changes from the working directory and save them without committing, then use git pop to restore them. For multiple stashes, save one with a name, locate it with git stash list, and restore it using git stash apply with its corresponding index.

Q: How does git bisect help find a commit that introduced a bug?

Start bisect from a commit known to contain the bug and identify the last known working commit. Git then performs a binary search through the commits between them; marking tested commits with bisect good eventually isolates the bad commit.

Q: How can you squash several Git commits into one?

From the feature branch, run interactive git rebase against the main branch and mark commits with squash to combine them into the original commit. Git then prompts you to update the resulting message; using fixup instead discards the combined messages. Commits prepared with fixup or squash flags can also be processed automatically with the autosquash rebase flag.

Q: How do you restore a local repository to match its remote version?

First run git fetch to retrieve the latest remote code, then use reset with the hard flag to overwrite the local code with the remote state. Local changes will be lost, and git clean can remove remaining untracked files or build artifacts.
