This volition detach your Caput, placing your running listing successful a indifferent Caput government. You tin past make a fresh subdivision from this component if wanted utilizing git checkout -b <fresh-subdivision-sanction>.
Alternatively, to reset your actual subdivision to a circumstantial perpetrate, usage git reset --difficult <perpetrate-hash>. Once more, retrieve this rewrites past and ought to beryllium utilized with warning.
For illustration, to revert to a perpetrate with the hash a1b2c3d4, you would usage git checkout a1b2c3d4 oregon git reset --difficult a1b2c3d4 relying connected whether or not you privation to detach Caput oregon reset the subdivision.
Fetching and Pulling from Distant
If the about new interpretation you’re trying for is connected a distant repository, usage git fetch to retrieve the newest modifications from the distant with out merging them into your section subdivision. Past, you tin usage git propulsion to merge the distant adjustments into your section subdivision. This ensures your section repository is ahead-to-day with the distant.
This is peculiarly applicable successful collaborative workflows wherever aggregate builders lend to the aforesaid task. Fetching and pulling repeatedly ensures you’re running with the newest codebase.
For case, to fetch from a distant named “root,” you’d usage git fetch root adopted by git propulsion root <subdivision-sanction> to merge the adjustments into your section subdivision.

FAQ
Q: What if I unintentionally usage git reset --difficult and suffer commits?
A: You tin possibly retrieve mislaid commits utilizing the reflog. Usage git reflog to position the past of Caput actions and past usage git reset --difficult <reflog-introduction> to reconstruct a circumstantial component successful clip.

Question & Answer :
I person late moved from SVN to Git and americium a spot confused astir thing. I wanted to tally the former interpretation of a book done a debugger, truthful I did git checkout <former interpretation hash> and did what I wanted to bash.
Present I privation to acquire backmost to the latest interpretation, however I don’t cognize the hash for it. Once I kind git log, I don’t seat it.
However tin I bash this? Besides, is location an simpler manner to alteration variations than by typing retired hashes - thing similar “spell backmost 2 variations” oregon “spell to the about chronologically new”?
git checkout maestro ought to bash the device. To spell backmost 2 variations, you may opportunity thing similar git checkout Caput~2, however amended to make a impermanent subdivision based mostly connected that clip, truthful git checkout -b temp_branch Caput~2
