This document provides information on various Git commands including git init, git config, git add, git reset, git commit, git log, git branch, git checkout, git merge, and others. It explains what each command does, such as git init creating an empty Git repository, git config setting user information, git add staging files, and git commit permanently storing file changes. It also covers basic branching and merging workflows.

1. Git Command

2. git work
index.html git index repository
git add index.html git commit ….

3. git config
Config file location: system、global、local
git config --global user.name "your name"
git config --global user.email "xxx@gmail.com"

4. git init
This command creates an empty Git repository - basically a .git directory with
subdirectories for objects, refs/heads, refs/tags, and template files. An initial
HEAD file that references the HEAD of the master branch is also created.

5. git status
Displays paths that have differences between the index file and the current HEAD
commit, paths that have differences between the working tree and the index file,
and paths in the working tree that are not tracked by Git

6. git add
This command updates the index using the current content found in the working
tree, to prepare the content staged for the next commit.
git add index.html index.css
git add .
git add --update

7. .gitignore file
A gitignore file specifies intentionally untracked files that Git should ignore. Files
already tracked by Git are not affected;
.gitignore content
*.css
!*.min.css
abc/*.txt
**/foo/bar
a/**/b

8. git reset
Reset current HEAD to the specified state
git reset
git reset index.html

9. git commit
Stores the current contents of the index in a new commit along with a log
message from the user describing the changes
git commit -m "commit message"
git commit --amend

10. git log
Shows the commit logs
git log
git log --stat
git log index.html
git log --author=’user name’
