Git is a powerful version control system which used to manage the code across multiple users and track changes across different versions.
Installation:
Download and install GIT from the below path
https://git-scm.com/download/win
Once installed, Git can be used as a version control system through various commands.
You can configure Git for a specific folder on your computer, allowing you to manage all changes to existing files and the addition of new files within that folder
Basic commands:
1. git init:
This will initialize new repository in the current directory. This also creates .git directory and store all version control information.
2. git config:
git config --global user.name "Ranjith "
git config --global user.mail "ranjith201099@gmail.com"
3. git status
Shows the current status of working area like staged, untracked and unstaged.
4. git add
add changes from working directory to the staging area, preparing them to commit.
To add specific file: git add "filename.py"
To add all changes git add .
5. git commit
git commit -m "<message>"
Commits the staged changes with descriptive mesage
6. git log
Displays the list of commit history for the repository.
It will show commit id, author, dates and commit changes
Creating a branch
git branch <branch_name> - to create branch
git checkout <branch_name> - to switch to the new branch
git branch -b <branch_name>
to create and switch to branch
git branch - to view all the branches (current branch will be highlighted with asterisk)
Merge a branch:
Once completed work on a branch and want to integrate it into another branch (like master), merging comes to place.
It means all the changes we have made in <branch_name> will be merged with master branch.
First, switch to the branch you want to merge into: git checkout master
Then, use git merge <branch_name> to merge your branch.
Deleting branch
Once the code changes in <branch_name> merged into <master> branch, we might need to delete branch.
use git branch -d <branch_name> to delete branch

These are common Git commands used in various situations:
start a working area (see also: git help tutorial)
clone Clone a repository into a new directory
init Create an empty Git repository or reinitialize an existing one
work on the current change (see also: git help everyday)
add Add file contents to the index
mv Move or rename a file, a directory, or a symlink
restore Restore working tree files
rm Remove files from the working tree and from the index
examine the history and state (see also: git help revisions)
bisect Use binary search to find the commit that introduced a bug
diff Show changes between commits, commit and working tree, etc
grep Print lines matching a pattern
log Show commit logs
show Show various types of objects
status Show the working tree status
grow, mark and tweak your common history
branch List, create, or delete branches
commit Record changes to the repository
merge Join two or more development histories together
rebase Reapply commits on top of another base tip
reset Reset current HEAD to the specified state
switch Switch branches
tag Create, list, delete or verify a tag object signed with GPG
collaborate (see also: git help workflows)
fetch Download objects and refs from another repository
pull Fetch from and integrate with another repository or a local branch
push Update remote refs along with associated objects
'git help -a' and 'git help -g' list available subcommands and some
concept guides. See 'git help <command>' or 'git help <concept>'
to read about a specific subcommand or concept.
See 'git help git' for an overview of the system.
