The use and understanding of the basic concepts of Git

Reference: https://www.liaoxuefeng.com/wiki/896043488029600

A), git use:

1. Create a repository (Resopsitory), equivalent to a directory with all the files are git management, each file will be modified with the deletion tracking and monitoring.

.git: Tracking Management Repository

Note: All versions of the controller can only track changes to the text, such as: .txt files, web pages, as well as program code, etc.

Two), git commands

git log: View commit log from the nearest to the farthest

git checkout: switching to the other branch

git checkout -: Modify command

git reset: fallback version, can also modify the temporary area retreated back to the work area

Note: * data will be submitted to the staging area to the master branch .git repository that is also capable of a fallback, ==== "can

      但需要一条件：即：没有把本地版本库推送到远程

$ Git push origin master: the latest modification of the local branch pushed to the remote repository

C) the use of visualization tools to see git history

HEAD: The current version

HEAD ^: the previous version

The previous version: HEAD ^^

HEAD ~ 100: 100 in up version

git reset: fall back to the previous version

git work area and staging area

Workspace: Creating a repository

git init command to create the repository can become Git repository management

.git: git repository, execute git init command, it will automatically generate a file in the repository .git directory created

D), add a remote repository

step

1. Create a local git repository
2. Creating a warehouse in gitHub (the warehouse as a backup, others through the warehouse Collaboration)
3. In order to run the local repository git repository associated gitHub
4. Local content will be pushed to the remote repository
   by $ git push origin master: the latest modification of the local branch pushed to github

Five), git code submission process

1. By git add: placing the file in the staging area
2. Use git commit: the staging area is placed in the branch file
   File ------ "-------- staging area" branch
   Note: You can add files to a plurality of staging area (Stage) , a one-time submission to the (master) on a branch
   when creating the repository, will automatically create a unique master

Six), git branch management

HEDA: The current version -------> master (branch) ---------> latest submitted

Create a new branch dev

Increase dev pointer:

HEDA (the current version) -------> dev -------- "the latest submitted

master ----- "the latest submitted

Modify dev branch submit updates

When submitting modifications to the work area, dev branch move, pointing to the latest submission, master point unchanged,

At this point the modifications and submit the work area is a branch for dev

dev branch work is completed, the combined main branch master

master points to the latest submission of dev, HEAD points to master

HEAD ----> master ------> the latest submitted dev

Seven), git advantages:

Definition: Distributed Version Control System

1. Networking also can not work
2. Branch Management
