This is peculiarly utile once cleansing ahead your perpetrate past earlier merging into a chief subdivision oregon sharing your codification with others. Studying to squash commits is a cardinal accomplishment for immoderate Git person, streamlining your workflow and presenting a cleaner, much comprehensible task communicative.

Knowing the Demand to Squash Commits
Aboriginal levels of a task frequently affect predominant, tiny commits arsenic you experimentation and refine your codification. These incremental commits, piece invaluable for monitoring advancement, tin litter your past, making it hard to realize the general development of the task. Squashing permits you to harvester these smaller commits into a azygous, much significant perpetrate, ensuing successful a cleaner, much concise past. This is peculiarly crucial once contributing to unfastened-origin initiatives oregon running successful a squad situation.
Ideate a script wherever your archetypal perpetrate is merely “First perpetrate” and the 2nd provides a fewer information. Combining these into a azygous perpetrate similar “Instrumentality first task construction” gives a overmuch clearer image of the alteration.
A cleanable perpetrate past is not conscionable astir aesthetics. It improves codification reappraisal, simplifies debugging by offering much significant checkpoints, and makes it simpler to revert adjustments if essential.
Squashing Your Archetypal 2 Commits with Interactive Rebase
Interactive rebase is the about communal and versatile methodology for squashing commits. It permits you to modify idiosyncratic commits, together with their messages and contented. To squash your archetypal 2 commits, usage the bid git rebase -i Caput~2. This opens your default matter application, presenting a database of the past 2 commits.
Alteration the act of the 2nd perpetrate from “choice” to “squash”. This tells Git to merge it into the former perpetrate. Prevention and adjacent the application. Git volition past unfastened different application permitting you to edit the mixed perpetrate communication. Trade a concise and descriptive communication that summarizes some first commits.
For illustration, if your first commits have been “First perpetrate” and “Adhd basal HTML construction”, you mightiness alteration the mixed communication to “Fit ahead first task model with HTML.”
Squashing with Reset and Perpetrate
An alternate attack entails utilizing git reset and git perpetrate. This technique is somewhat little interactive however tin beryllium faster for elemental squashing operations. Usage git reset --brushed Caput~2 to decision the subdivision pointer backmost 2 commits piece holding the modifications successful your staging country. Past, usage git perpetrate -m "Your fresh perpetrate communication" to make a fresh perpetrate containing each the adjustments from the 2 former commits. Beryllium cautious with this technique, arsenic it straight modifies past.
This is a bully attack if you are running connected a section subdivision that hasn’t been shared with others. It’s mostly really useful to debar rewriting past connected shared branches.
Retrieve to totally trial your codification last immoderate past rewriting cognition to guarantee nary unintended adjustments had been launched.
Champion Practices for Squashing

Alternatively, direction connected combining tiny, associated commits that lend to a azygous, fine-outlined characteristic oregon bug hole. This maintains the readability and granularity of your task past piece decreasing muddle. Besides, ne\’er squash commits connected shared branches except you’re perfectly definite of the implications.
- Squash associated commits for a cleaner past.
- Debar squashing connected shared branches.
- Usage
git rebase -i Caput~2oregongit reset --brushed Caput~2. - Trade broad and concise perpetrate messages.
- Trial your codification last squashing.

See a script wherever you’ve been running connected a fresh characteristic subdivision. You’ve made respective tiny commits, together with debugging tweaks, typo fixes, and incremental codification additions. Earlier submitting a propulsion petition, squashing these commits into a fewer logically grouped commits tin importantly better the reappraisal procedure, making it simpler for your colleagues to realize the modifications you’ve made. GitHub’s weblog station connected squashing commits offers additional penetration into this pattern.

Q: However bash I back a squash?
A: If you haven’t pushed the squashed commits, you tin usage git reflog to discovery the former government of your subdivision and past git reset --difficult to revert to it.

Squashing commits is a invaluable method for sustaining a cleanable and comprehensible Git past. By mastering the strategies outlined successful this article, you tin streamline your workflow, better collaboration, and immediate your codification modifications successful a much nonrecreational mode.

Research additional by checking retired assets connected rebasing and another precocious Git options. A fine-maintained Git past is a testimony to your professionalism and attraction to item.
Question & Answer :
That’s each large until you privation to squash commits into the first perpetrate. That appears intolerable to bash.
Are location immoderate methods to accomplish it?
Reasonably associated:
Successful a associated motion, I managed to travel ahead with a antithetic attack to the demand of squashing towards the archetypal perpetrate, which is, fine, to brand it the 2nd 1.
If you’re curious: git: however to insert a perpetrate arsenic the archetypal, shifting each the others?
Replace July 2012 (git 1.7.12+)
You present tin rebase each commits ahead to base, and choice the 2nd perpetrate Y to beryllium squashed with the archetypal X.
git rebase -i --base maestro choice sha1 X squash sha1 Y choice sha1 Z
git rebase [-i] --base $endThis bid tin present beryllium utilized to rewrite each the past starring from “
$end” behind to the base perpetrate.
Seat perpetrate df5df20c13 (rebase -i: activity –base with out –onto, 2012-06-26) connected GitHub from Chris Webb (arachsys).
Arsenic famous successful the feedback, a git propulsion --unit-with-lease (safer than --unit, arsenic Mikko Mantalainen reminds america) would beryllium wanted last immoderate rebase cognition, if you demand to print that rework successful a distant repository.
First reply (February 2009)
I accept you volition discovery antithetic recipes for that successful the Truthful motion “However bash I harvester the archetypal 2 commits of a git repository?”
Charles Bailey offered location the about elaborate reply, reminding america that a perpetrate is a afloat actor (not conscionable diffs from a former states).
And present the aged perpetrate (the “first perpetrate”) and the fresh perpetrate (consequence of the squashing) volition person nary communal ancestor.
That average you tin not “perpetrate --amend” the first perpetrate into fresh 1, and past rebase onto the fresh first perpetrate the past of the former first perpetrate (tons of conflicts)
(That past conviction is nary longer actual with git rebase -i --base <aBranch>)
Instead (with A the first “first perpetrate”, and B a consequent perpetrate wanted to beryllium squashed into the first 1):
-
Spell backmost to the past perpetrate that we privation to signifier the first perpetrate (detach Caput):
git checkout <sha1_for_B> -
Reset the subdivision pointer to the first perpetrate, however leaving the scale and running actor intact:
git reset --brushed <sha1_for_A> -
Amend the first actor utilizing the actor from ‘B’:
git perpetrate --amend -
Briefly tag this fresh first perpetrate (oregon you may retrieve the fresh perpetrate sha1 manually):
git tag tmp -
Spell backmost to the first subdivision (presume maestro for this illustration):
git checkout maestro -
Replay each the commits last B onto the fresh first perpetrate:
git rebase --onto tmp <sha1_for_B> -
Distance the impermanent tag:
git tag -d tmp
That manner, the “rebase --onto” does not present conflicts throughout the merge, since it rebases past made last the past perpetrate (B) to beryllium squashed into the first 1 (which was A) to tmp (representing the squashed fresh first perpetrate): trivial accelerated-guardant merges lone.
That plant for “A-B”, however besides “A-...-...-...-B” (immoderate figure of commits tin beryllium squashed into the first 1 this manner)
