GitHub Basics

Distributed Version Control System(Github)

IMPORTANT BASICS COMMANDS TO WORK WITH CODEBASE

1. Version of the Github (Ccheck the version)
git --version


2. Set config values

git config --global user.name "xyz"
git config --global user.email "abc@gmail.com" 

List the information regarding configurations

git config --list

3. Help regarding git commands

Example 1:
git help config
git config --help

Example 2:

git help add

git add --help


3. Initializing the repository from existing CODE 

before going for initalization of a repository do the following

ls 
ls -la  // it will show hidden files

git init // Initializing local repository

check  using ls -la

4.If we want to deactive as a repository (Untracking)

rm -rf .git

5. Before first commit

a) git status

If we want to ignore files

touch .gitignore

6.  Working directory ---->  Staging Area  ----->  .git directory(Repository)

7. Adding files to staging Area

git add .gitignore // only .gitignore file in stating area

git add -A // All files in staging area

8. Remove files from stating area

git reset .gitignore // remove only .gitignore from staging area

git reset // remove all files from staging area

git add -A // Add all files to staging area

9. Our first commit

git commit -m "label"

git status // how many commits are still pending

git log //log information time stamp


10. Cloning a remote repository

git clone <url>

git clone <url> . 

11. Viewing information about remote repository

git remote -v // information of repository

git branch -a  // all branches in repository either local or global


12.  Push changes

git diff // changes in made CODE

git status

git add -A

git commit -m "Label"

THEN PUSH 

git pull origin master // when working with multiple people working with on the same file and need to 
update in the local repository

git push origin master // push changes made in code base of master in local repository to remote repository


13. COMMON WORKFLOW 

A) CREATE A BRANCH FOR DESIRED FEATURE

git branch calcualtor //create a branch with name calcualtor

git checkout calcualtor // switch or toggle from master branch  to calcualtor

git branch // know the status of current branch

git status // status of file if any modificaiton  

git add -A 

git commit -m "Label"


B) After commit push branch to remote

git branch -a 

git push -u origin calcualtor

C) MERGE calcualtor branch to remote master

git checkout master //swithc  from calcualtor to  master

git pull origin master // if any modificaiton done by others on master

git branch --merged // status is Not yet merged calcualtor branch to master

git merge calcualtor // merge calcualtor branch to remote master 

git push origin master // push record of local repository master to remote master repository

git branch --merge // status is  merged calcualtor branch to master 

D) DELETING A BRANCH

git branch --merged 

git branch -d calcualtor

git branch -a 

git push origin --delete calcualtor 

git branch -a 

14. FASTER Example

A) git branch sub

B) git checkout sub

C) git status 


D) git add -Add

E) git commit -m "Label"

F) git push -u origin sub

G) git checkout master

H) git pull origin master 

I) git merge sub

J) git push origin master 
 



Tutorial 2:

15. git status

git diff

git checkout file.txt // rollback changes if any in file.txt

git commit -m "Subtract" // wrong commit message 

git log // this is different

git commit --amend -m "Add" // Subtract commit is replced by Add

git log // this is different
