Git Revert

revert 是我們用來將之前的 commit 新增為新的 commit，同時保持 log 不變。

步驟 1：查詢之前的 commit

步驟 2：使用它來建立一個新的 commit

讓我們建立一個新的 commit，其中我們“意外”刪除了一個檔案

git commit -m "Just a regular update, definitely no accidents here..."
[master 16a6f19] Just a regular update, definitely no accidents here...
 1 file changed, 0 insertions(+), 0 deletions(-)
 delete mode 100644 img_hello_git.jpg

現在我們的 commit 歷史中有一部分是我們想要回退的。讓我們嘗試使用 revert 來做到這一點。

Git Revert 在 Log 中查詢 Commit

首先，我們需要找到我們想要返回的點。為此，我們需要瀏覽 log。

為了避免非常長的日誌列表，我們將使用 --oneline 選項，它每行顯示一個提交，包含

• commit hash 的前七個字元
• commit message

所以，讓我們找到我們想要 revert 的點

git log --oneline
52418f7 (HEAD -> master) Just a regular update, definitely no accidents here...
9a9add8 (origin/master) Added .gitignore
81912ba Corrected spelling error
3fdaa5b Merge pull request #1 from w3schools-test/update-readme
836e5bf (origin/update-readme, update-readme) Updated readme for GitHub Branches
daf4f7c (origin/html-skeleton, html-skeleton) Updated index.html with basic meta
facaeae (gh-page/master) Merge branch 'master' of https://github.com/w3schools-test/hello-world
e7de78f Updated index.html. Resized image
5a04b6f Updated README.md with a line about focus
d29d69f Updated README.md with a line about GitHub
e0b6038 merged with hello-world-images after fixing conflicts
1f1584e added new image
dfa79db updated index.html with emergency fix
0312c55 Added image to Hello World
09f4acd Updated index.html with a new line
221ec6e First release of Hello World!

我們想回退到之前的 commit: 52418f7 (HEAD -> master) Just a regular update, definitely no accidents here...，我們看到這是最新的 commit。

Git Revert HEAD

我們使用 git revert HEAD（revert 最新的更改，然後 commit）來回退最新的 commit，並新增 --no-edit 選項來跳過提交訊息編輯器（獲取預設的 revert 訊息）

git revert HEAD --no-edit
[master e56ba1f] Revert "Just a regular update, definitely no accidents here..."
 Date: Thu Apr 22 10:50:13 2021 +0200
 1 file changed, 0 insertions(+), 0 deletions(-)
 create mode 100644 img_hello_git.jpg

現在讓我們再次檢查 log

git log --oneline
e56ba1f (HEAD -> master) Revert "Just a regular update, definitely no accidents here..."
52418f7 Just a regular update, definitely no accidents here...
9a9add8 (origin/master) Added .gitignore

在下一頁，我們將介紹 git reset，它會將儲存庫恢復到之前的提交狀態，而不會建立新的 commit。
