Git 基础 应用场景

• 使用独立分支和拉取请求（Pull Request）工作流管理功能开发。
• 将本地代码库与 GitHub 或 GitLab 等远程仓库同步。
• 使用 git blame 和 git bisect 等历史工具调试代码回退。
• 撤销意外更改或清理工作区中未跟踪的文件。
• 通过使用带注释的标签和版本控制来组织项目发布。

Git 基础 工作原理

1. 初始化或克隆仓库以开始跟踪项目文件和元数据。
2. 使用暂存区有选择地准备要包含在项目历史记录中的更改。
3. 创建描述性的提交以记录进度并维护所有修改的可搜索日志。
4. 利用分支策略将新功能或紧急修复与主生产代码隔离。
5. 与远程服务器同步更改，使用 fetch、pull 和 push 操作与其他团队成员协作。

Git 基础 配置指南

如果系统中尚未安装 git 二进制文件，请先进行安装。然后，配置您的全局身份以开始有效地使用这些 Openclaw Skills：

# 配置用户身份
git config --global user.name "Your Name"
git config --global user.email "[email protected]"

# 初始化新仓库
git init

# 克隆现有项目
git clone https://github.com/user/repo.git

Git 基础 数据架构与分类体系

组件	描述
.git/	Git 存储所有版本历史、对象和元数据的内部目录。
.gitignore	一个指定哪些文件和模式应被版本控制忽略的文本文件。
HEAD	指向当前检出的提交或分支的特殊指针。
暂存区 (Staging Area)	跟踪打算包含在下次提交中的更改的中间索引。
远程引用 (Remote Refs)	引用远程仓库上分支的状态，例如 origin/main。

Git Essentials

Essential Git commands for version control and collaboration.

Initial Setup

# Configure user
git config --global user.name "Your Name"
git config --global user.email "[email protected]"

# Initialize repository
git init

# Clone repository
git clone https://github.com/user/repo.git
git clone https://github.com/user/repo.git custom-name

Basic Workflow

Staging and committing

# Check status
git status

# Add files to staging
git add file.txt
git add .
git add -A  # All changes including deletions

# Commit changes
git commit -m "Commit message"

# Add and commit in one step
git commit -am "Message"

# Amend last commit
git commit --amend -m "New message"
git commit --amend --no-edit  # Keep message

Viewing changes

# Show unstaged changes
git diff

# Show staged changes
git diff --staged

# Show changes in specific file
git diff file.txt

# Show changes between commits
git diff commit1 commit2

Branching & Merging

Branch management

# List branches
git branch
git branch -a  # Include remote branches

# Create branch
git branch feature-name

# Switch branch
git checkout feature-name
git switch feature-name  # Modern alternative

# Create and switch
git checkout -b feature-name
git switch -c feature-name

# Delete branch
git branch -d branch-name
git branch -D branch-name  # Force delete

# Rename branch
git branch -m old-name new-name

Merging

# Merge branch into current
git merge feature-name

# Merge with no fast-forward
git merge --no-ff feature-name

# Abort merge
git merge --abort

# Show merge conflicts
git diff --name-only --diff-filter=U

Remote Operations

Managing remotes

# List remotes
git remote -v

# Add remote
git remote add origin https://github.com/user/repo.git

# Change remote URL
git remote set-url origin https://github.com/user/new-repo.git

# Remove remote
git remote remove origin

Syncing with remote

# Fetch from remote
git fetch origin

# Pull changes (fetch + merge)
git pull

# Pull with rebase
git pull --rebase

# Push changes
git push

# Push new branch
git push -u origin branch-name

# Force push (careful!)
git push --force-with-lease

History & Logs

Viewing history

# Show commit history
git log

# One line per commit
git log --oneline

# With graph
git log --graph --oneline --all

# Last N commits
git log -5

# Commits by author
git log --author="Name"

# Commits in date range
git log --since="2 weeks ago"
git log --until="2024-01-01"

# File history
git log -- file.txt

Searching history

# Search commit messages
git log --grep="bug fix"

# Search code changes
git log -S "function_name"

# Show who changed each line
git blame file.txt

# Find commit that introduced bug
git bisect start
git bisect bad
git bisect good commit-hash

Undoing Changes

Working directory

# Discard changes in file
git restore file.txt
git checkout -- file.txt  # Old way

# Discard all changes
git restore .

Staging area

# Unstage file
git restore --staged file.txt
git reset HEAD file.txt  # Old way

# Unstage all
git reset

Commits

# Undo last commit (keep changes)
git reset --soft HEAD~1

# Undo last commit (discard changes)
git reset --hard HEAD~1

# Revert commit (create new commit)
git revert commit-hash

# Reset to specific commit
git reset --hard commit-hash

Stashing

# Stash changes
git stash

# Stash with message
git stash save "Work in progress"

# List stashes
git stash list

# Apply latest stash
git stash apply

# Apply and remove stash
git stash pop

# Apply specific stash
git stash apply stash@{2}

# Delete stash
git stash drop stash@{0}

# Clear all stashes
git stash clear

Rebasing

# Rebase current branch
git rebase main

# Interactive rebase (last 3 commits)
git rebase -i HEAD~3

# Continue after resolving conflicts
git rebase --continue

# Skip current commit
git rebase --skip

# Abort rebase
git rebase --abort

Tags

# List tags
git tag

# Create lightweight tag
git tag v1.0.0

# Create annotated tag
git tag -a v1.0.0 -m "Version 1.0.0"

# Tag specific commit
git tag v1.0.0 commit-hash

# Push tag
git push origin v1.0.0

# Push all tags
git push --tags

# Delete tag
git tag -d v1.0.0
git push origin --delete v1.0.0

Advanced Operations

Cherry-pick

# Apply specific commit
git cherry-pick commit-hash

# Cherry-pick without committing
git cherry-pick -n commit-hash

Submodules

# Add submodule
git submodule add https://github.com/user/repo.git path/

# Initialize submodules
git submodule init

# Update submodules
git submodule update

# Clone with submodules
git clone --recursive https://github.com/user/repo.git

Clean

# Preview files to be deleted
git clean -n

# Delete untracked files
git clean -f

# Delete untracked files and directories
git clean -fd

# Include ignored files
git clean -fdx

Common Workflows

Feature branch workflow:

git checkout -b feature/new-feature
# Make changes
git add .
git commit -m "Add new feature"
git push -u origin feature/new-feature
# Create PR, then after merge:
git checkout main
git pull
git branch -d feature/new-feature

Hotfix workflow:

git checkout main
git pull
git checkout -b hotfix/critical-bug
# Fix bug
git commit -am "Fix critical bug"
git push -u origin hotfix/critical-bug
# After merge:
git checkout main && git pull

Syncing fork:

git remote add upstream https://github.com/original/repo.git
git fetch upstream
git checkout main
git merge upstream/main
git push origin main

Useful Aliases

Add to ~/.gitconfig:

[alias]
    st = status
    co = checkout
    br = branch
    ci = commit
    unstage = reset HEAD --
    last = log -1 HEAD
    visual = log --graph --oneline --all
    amend = commit --amend --no-edit

Tips

• Commit often, perfect later (interactive rebase)
• Write meaningful commit messages
• Use .gitignore for files to exclude
• Never force push to shared branches
• Pull before starting work
• Use feature branches, not main
• Rebase feature branches before merging
• Use --force-with-lease instead of --force

Common Issues

Undo accidental commit:

git reset --soft HEAD~1

Recover deleted branch:

git reflog
git checkout -b branch-name 

Fix wrong commit message:

git commit --amend -m "Correct message"

Resolve merge conflicts:

# Edit files to resolve conflicts
git add resolved-files
git commit  # Or git merge --continue
