Git menawarake akeh cara kanggo **mbatalke owah-owahan** gumantung ing situasi — ngilangake owah-owahan sing durung di-commit, mbatalke staging, ngowahi commit paling anyar, mbatalke commit, utawa reset. Ngerti tool sing pas kanggo saben situasi iku penting, skill praktis sing berharga. ## Mbatalke owah-owahan sing durung di-commit (working directory) ```bash git restore # discard unstaged changes to a file (revert to last commit) git checkout -- # older equivalent git restore . # discard ALL unstaged changes (careful!) git clean -fd # remove untracked files/directories ``` ## Mbatalke staging (tetep owah-owahan, mung mbatalke staging) ```bash git restore --staged # unstage a file (changes stay in working dir) git reset # older equivalent ``` ## Ngowahi utawa amend commit paling anyar ```bash git commit --amend -m "New message" # change the last commit's message git commit --amend # add staged changes to the last commit # ⚠️ amend REWRITES the commit — don't amend commits already pushed/shared ``` ## Mbatalke owah-owahan sing wis di-commit ```text TWO main approaches: REVERT → creates a NEW commit that undoes a previous commit (SAFE for shared history) git revert → history preserved; the undo is itself a commit RESET → moves the branch pointer BACK (rewrites history — for LOCAL commits only) git reset --soft HEAD~1 → undo commit, KEEP changes staged git reset --mixed HEAD~1 → undo commit, keep changes unstaged (default) git reset --hard HEAD~1 → undo commit AND DISCARD changes (⚠️ destructive!) ``` ## revert vs reset (pilihan utama) ```text REVERT → safe for PUBLIC/shared commits (adds a new undoing commit; doesn't rewrite history) RESET → rewrites history (only for LOCAL, unpushed commits; never on shared branches) → Rule: use REVERT to undo commits others may have; RESET only for local cleanup. ``` ## Apa peranan-e Ngerti carane mbatalke owah-owahan ing Git iku penting, skill praktis sing asring dibutuhake, amarga kesalahan lan keperluwan mbatalke kerja iku ora bisa dihindari ing development, lan Git menyediakake cara-cara kuat (nanging spesifik situasi) kanggo mbalekake. Ngerti **tool sing pas kanggo saben situasi** iku skill utama: ngilangake **owah-owahan sing durung di-commit** (`git restore` kanggo mbatalke editing working-directory, `git clean` kanggo file sing durung dilacak), **mbatalke staging** (`git restore --staged` kanggo tetep owah-owahan nanging mbatalke staging-e), **ngamend** commit paling anyar (ngowahi pesan-e utawa nambah-nambah - kanthi catatan penting ora ngowahi commit sing wis di-push amarga iku nuliso sejarah), lan mbatalke owah-owahan **sing wis di-commit**. Kanggo mbatalke commit, ngerti **perbedaan kritis antara revert lan reset** iku luwih penting: **`revert`** nggawe commit anyar sing mbatalke commit sadurunge lan iku **aman kanggo sejarah sing dibagi/umum** (iku ora nuliso sejarah, mula ora bakal ganggu wong liya), dene **`reset`** nggerak branch pointer bali lan **nuliso sejarah**, nggawa iku cocok mung kanggo **commit lokal sing durung di-push** (lan `reset --hard` iku destruktif, ngilangake owah-owahan). Aturan - nggunakake `revert` kanggo commit sing isih ana ing panggonan liya, `reset` mung kanggo pembersihan lokal - iku penting amarga nuliso sejarah sing dibagi (via reset ing commit sing dipush) nggawe masalah serius kanggo kolaborator. Ngerti pilihan-pilihan iki nyegah kelangan kerja (nggunakake perintah destruktif kanthi sembrono) lan gangguan kolaborasi (nuliso sejarah sing dibagi). Amarana mbatalke owah-owahan iku kebutuhan umum, ora bisa dihindari lan Git menawarake akeh pendekatan spesifik situasi kanthi implikasi keamanan penting (luwih-luwih revert vs reset kanggo sejarah sing dibagi), ngerti carane mbatalke owah-owahan ing Git - tool sing pas kanggo saben skenario lan perbedaan kritis revert-vs-reset - iku ilmu praktis sing berharga, asring digunakake kanggo nggarap Git kanthi percaya diri lan aman, skill sing nggawe kekhawatiran kesalahan dadi pemulihan rutin lan ngindari jebakan serius yaiku nuliso sejarah sing dibagi.

Mbatalke owah-owahan sing durung di-commit (working directory)

Mbatalke staging (tetep owah-owahan, mung mbatalke staging)

Ngowahi utawa amend commit paling anyar

Mbatalke owah-owahan sing wis di-commit

revert vs reset (pilihan utama)
