我刚才提交了什么?

(main)$ git show

$ git log -n1 -p

我的提交信息(commit message)写错了

$ git commit --amend --only

$ git commit --amend --only -m 'xxxxxxx'

我提交(commit)里的用户名和邮箱不对

$ git commit --amend --author "New Authorname <authoremail@mydomain.com>"

我想从一个提交(commit)里移除一个文件

$ git checkout HEAD^ myfile$ git add -A$ git commit --amend

我想删除我的的最后一次提交(commit)

$ git reset HEAD^ --hard$ git push -f [remote] [branch]

(my-branch*)$ git reset --soft HEAD@{1}

删除任意提交(commit)

$ git rebase --onto SHA1_OF_BAD_COMMIT^ SHA1_OF_BAD_COMMIT$ git push -f [remote] [branch]

我尝试推一个修正后的提交(amended commit)到远程，但是报错：

To https://github.com/yourusername/repo.git! [rejected]        mybranch -> mybranch (non-fast-forward)error: failed to push some refs to 'https://github.com/tanay1337/webmaker.org.git'hint: Updates were rejected because the tip of your current branch is behindhint: its remote counterpart. Integrate the remote changes (e.g.hint: 'git pull ...') before pushing again.hint: See the 'Note about fast-forwards' in 'git push --help' for details.

(my-branch)$ git push origin mybranch -f

我意外的做了一次硬重置(hard reset)，我想找回我的内容

(main)$ git reflog

(main)$ git reset --hard SHA1234

暂存(Staging)

我需要把暂存的内容添加到上一次的提交(commit)

(my-branch*)$ git commit --amend

我想要暂存一个新文件的一部分，而不是这个文件的全部

$ git add --patch filename.x

$ git add -N filename.x

我想把在一个文件里的变化(changes)加到两个提交(commit)里

我想把暂存的内容变成未暂存，把未暂存的内容暂存起来

$ git commit -m "WIP"$ git add .$ git stash$ git reset HEAD^$ git stash pop --index 0

未暂存(Unstaged)的内容

我想把未暂存的内容移动到一个新分支

$ git checkout -b my-branch

我想把未暂存的内容移动到另一个已存在的分支

$ git stash$ git checkout my-branch$ git stash pop

我想丢弃本地未提交的变化(uncommitted changes)

# one commit(my-branch)$ git reset --hard HEAD^# two commits(my-branch)$ git reset --hard HEAD^^# four commits(my-branch)$ git reset --hard HEAD~4# or(main)$ git checkout -f

$ git reset filename

我想丢弃某些未暂存的内容

$ git checkout -p# Answer y to all of the snippets you want to drop

$ git stash -p# Select all of the snippets you want to save$ git reset --hard$ git stash pop

$ git stash -p# Select all of the snippets you don't want to save$ git stash drop

分支(Branches)

我从错误的分支拉取了内容，或把内容拉取到了错误的分支

(main)$ git reflogab7555f HEAD@{0}: pull origin wrong-branch: Fast-forwardc5bc55a HEAD@{1}: checkout: checkout message goes here

$ git reset --hard c5bc55a

我想扔掉本地的提交(commit)，以便我的分支与远程的保持一致

(my-branch)$ git status# On branch my-branch# Your branch is ahead of 'origin/my-branch' by 2 commits.#   (use "git push" to publish your local commits)#

(main)$ git reset --hard origin/my-branch

我需要提交到一个新分支，但错误的提交到了main

(main)$ git branch my-branch

(main)$ git reset --hard HEAD^

(main)$ git reset --hard a13b85eHEAD is now at a13b85e

(main)$ git checkout my-branch

我想保留来自另外一个ref-ish的整个文件

(solution)$ git add -A && git commit -m "Adding all changes from this spike into one big commit."

• 分支 solution, 拥有原型方案， 领先 develop 分支。
• 分支 develop, 在这里你应用原型方案的一些内容。

(develop)$ git checkout solution -- file1.txt

# On branch develop# Your branch is up-to-date with 'origin/develop'.# Changes to be committed:#  (use "git reset HEAD <file>..." to unstage)##        modified:   file1.txt

我把几个提交(commit)提交到了同一个分支，而这些提交应该分布在不同的分支里

(main)$ git log

    First commit

(21)$ git cherry-pick e3851e8

(21)$ git checkout main(main)$ git checkout -b 14(14)$

(14)$ git cherry-pick 5ea5173

我想删除上游(upstream)分支被删除了的本地分支

$ git fetch -p

我不小心删除了我的分支

(main)$ git checkout -b my-branch(my-branch)$ git branch(my-branch)$ touch foo.txt(my-branch)$ lsREADME.md foo.txt

我想删除一个分支

(main)$ git push origin --delete my-branch

(main)$ git push origin :my-branch

(main)$ git branch -D my-branch

我想从别人正在工作的远程分支签出(checkout)一个分支

(main)$ git fetch --all

(main)$ git checkout --track origin/davesBranch daves set up to track remote branch daves from origin.Switched to a new branch 'daves'

Rebasing 和合并(Merging)

我想撤销rebase/merge

(my-branch)$ git reset --hard ORIG_HEAD

我已经rebase过, 但是我不想强推(force push)

(main)$ git checkout my-branch(my-branch)$ git rebase -i main(my-branch)$ git checkout main(main)$ git merge --ff-only my-branch

我需要组合(combine)几个提交(commit)

(my-branch)$ git reset --soft main(my-branch)$ git commit -am "New awesome feature"

(my-branch)$ git rebase -i main

(main)$ git rebase -i HEAD~2

pick a9c8a1d Some refactoringpick 01b2fd8 New awesome featurepick b729ad5 fixuppick e3851e8 another fix
# Rebase 8074d12..b729ad5 onto 8074d12## Commands:#  p, pick = use commit#  r, reword = use commit, but edit the commit message#  e, edit = use commit, but stop for amending#  s, squash = use commit, but meld into previous commit#  f, fixup = like "squash", but discard this commit's log message#  x, exec = run command (the rest of the line) using shell## These lines can be re-ordered; they are executed from top to bottom.## If you remove a line here THAT COMMIT WILL BE LOST.## However, if you remove everything, the rebase will be aborted.## Note that empty commits are commented out

pick a9c8a1d Some refactoringpick 01b2fd8 New awesome featuref b729ad5 fixupf e3851e8 another fix

pick a9c8a1d Some refactoringpick 01b2fd8 New awesome features b729ad5 fixups e3851e8 another fix

# Please enter the commit message for your changes. Lines starting# with '#' will be ignored, and an empty message aborts the commit.# rebase in progress; onto 8074d12# You are currently editing a commit while rebasing branch 'main' on '8074d12'.## Changes to be committed:#  modified:   README.md#

(main)$ Successfully rebased and updated refs/heads/main.

安全合并(merging)策略

(main)$ git merge --no-ff --no-commit my-branch

我需要将一个分支合并成一个提交(commit)

(main)$ git merge --squash my-branch

我只想组合(combine)未推的提交(unpushed commit)

(main)$ git rebase -i @{u}

检查是否分支上的所有提交(commit)都合并(merge)过了

(main)$ git log --graph --left-right --cherry-pick --oneline HEAD...feature/120-on-scroll

(main)$ git log main ^feature/120-on-scroll --no-merges

交互式rebase(interactive rebase)可能出现的问题

这个rebase 编辑屏幕出现'noop'

noop

• 检查确保主(main)分支没有问题
• rebase  HEAD~2 或者更早

有冲突的情况

(my-branch)$ git statusOn branch my-branchChanges not staged for commit:  (use "git add <file>..." to update what will be committed)  (use "git checkout -- <file>..." to discard changes in working directory)
 modified:   README.md

   <<<<<<< HEAD   some code   =========   some code   >>>>>>> new-commit

(main*)$ git mergetool -t opendiff

(my-branch)$ git add README.md(my-branch)$ git rebase --continue

(my-branch)$ git rebase --abort

Stash

暂存所有改动

$ git stash

$ git stash -u

暂存指定文件

$ git stash push working-directory-path/filename.ext

$ git stash push working-directory-path/filename1.ext working-directory-path/filename2.ext

暂存时记录消息

$ git stash save <message>

$ git stash push -m <message>

使用某个指定暂存

$ git stash list

$ git stash apply "stash@{n}"

$ git stash apply "stash@{2.hours.ago}"

暂存时保留未暂存的内容

$ git stash create$ git stash store -m
