GIT works on 3 stages-->
1.) Present working directory --> the directory on computer whuch is git directory and on which the project is worked on
2.) Staging Area --> the area where the where the files are sent which are needed to be pushed on to the repository
3.) Git repository --> The files are commited here using commit command
 

git init --> to make a directory as git directory and git will start tracking changes in that directory

--> For configuring username and email for git . Used for local configuration
git config user.name "<user-name>"
git config user.email "<user-email>"

--> For global configuration
git config --global user.name "<user-name>"
git config --global user.email "<user-email>"

--> To get the list and username and user email
git config --list  

--> tells that new file is added or present files were modified or if the directory is under git or not
git status

--> Takes all the file to the staging area which will be commited further
git add --a

--> Takes a specific file to the staging area
git add <filename>

--> Commiting the files -m is message ,  before commiting files should be added first 
git commit -m "<commit message>"
Example--> git commit -m "First commit"

--> Opens the present working directory in the vs code
code .


--> Clears the terminal
clear

--> shows all the commits made onthe directory
git log

CLONING A PROJECT

--> cloning git repository
git clone <URL>

--> to show all the files and folders in the directory
ls


////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
IGNORING A FILE DURING COMMITING OR ADDING

1.) make a .gitignore file
2.) Enter the filename to be ignored while pushing and to ignore a folder write <folder-name>/ in .gitignore file
3.) To ignore all files of a particular extension write *.<file-extension> in .gitignore file 
 Example--> to ignore all .txt file add *.txt to .gitignore file.
4.) add and commit the files. 



////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

--> To see the diffrence between working directory and staged data
git diff

--> To compare staged data with last commit 
git diff --staged	

--> directly commiting files without adding or moving files from present working directory to repository
git commit -a -m "<message>"




////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

UNSTAGING AND UNMODIFYING FILES IN GIT

--> To remove a file form staged position
git restore --staged <file-name>


--> To get the file from staging area
git restore <file-name>

--> to get all the files from staging area 
git restore .

--> to get the file from last commit
git checkout <file-name>

--> to get all the files from the last commit
git checkout -f


////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

--> When a file is renamed after commiting by a diffrent name in git then the git shows that the file was deleted and new file was formed
    having the name as the renamed name.

--> After adding the file git recognizes that the file was actually renamed and no files were deleted.	

--> using mv command we can rename the file and the dit knows it without staging it
git mv <current-file-name> <file-name-to-replace>

--> To remove a file
git rm <file-name>

--> To stop git from tracking a file which was being tracked previously
git rm --cached <file-name>
After running above code git status shows that the file is deleted.

WORKING ON REMOTE REPOSITORY

1.) MAKING NEW REPOSITORY by pressing + button on top left and then giving repository name.
2.) -->Connecting a repository to local git
git remote add origion <link>   
3.) Generate an SSH key by searching at google to push the code to github
