Git concepts

1. What is Git?
Git is a distributed version control system that is commonly used for
software development projects. It allows multiple developers to work on
the same codebase simultaneously. It tracks changes, maintains different
versions of the code, and helps in collaboration.

2. Why use Git?
Collaborative
Development
Git enables seamless
collaboration among
developers by managing and
tracking changes in the
codebase, making it easier to
work together on projects.
Efficiency
Using Git streamlines the
development process, allowing
for faster and more efficient
management of code changes
and releases.
Version Control
Git provides a structured
approach to version control,
ensuring that previous versions
of the code are accessible and
revertible when needed.

3. Basic Git commands:
1 git init
Initializes a local
directory as a new Git
repository, enabling
version control for the
project.
2 git add
Stages changes in the
working directory,
preparing them to be
included in the next
commit.
3 git commit
Records changes to the
repository, creating a
checkpoint that allows
for future reference and
retrieval.
4 git status
Displays the state of the working directory
and any changes that are not yet staged
for commit.
5 git log
Shows a chronological history of commits,
including details about authors,
timestamps, and specific changes made.

4. Branching in Git:
1 Single Main Branch
By default, Git creates a primary branch called "master," representing the
main line of development.
2 Creating New Branches
Developers can create separate branches to work on new features or bug
fixes without impacting the main codebase.
3 Merging Branches
Git provides the ability to merge changes from one branch into another,
integrating new code while preserving development history.

5. Collaborative Remote Development:
Pushing & Pulling
Git allows developers to push
their local changes to a
remote repository and pull
changes made by others.
Remote Branches
Git enables the tracking of
remote branches, facilitating
collaboration and updates
with distributed teams.
Conflict Resolution
Remote development with Git
includes features for resolving
conflicts and maintaining
code consistency across
contributors.

6. Stashing and Pop:
1 Stashing Changes
Developers can temporarily store changes
with Git, allowing for the switch to another
task while retaining the current work.
2 Pop
if Something has changed and you want to
take another change without commiting
pop come into picture

7. Git Rebase and Reset:
1 Rebasing Commits
Git rebase allows developers to apply a
sequence of commits from one branch to
another, maintaining a linear project
history.
2 Resetting Changes
With Git reset, developers can revert
changes, selectively discard commits, and
restore the repository to a previous state.

8. Git Hooks and Workflows:
1 Using Hooks
Git hooks enable the execution of
custom scripts and automation at
specific points in the version control
workflow.
2 Workflow Strategies
Git supports various workflows,
including centralized, feature
branch, and gitflow, catering to
diverse project needs.

9. Git Graph and Visualization:
1 Commit Graphs
Visual representations of git commit
history and branches provide
insights and aid in understanding
project evolution.
2 Visualization Tools
Git visualization tools offer
interactive interfaces for exploring
commits, branches, and repository
changes visually.

10. Git Best Practices:
1 Commit Frequently
Regular small commits help in tracking changes and make it easier to identify and
isolate issues if they arise.
2 Use Meaningful Messages
Clear and descriptive commit messages provide valuable context and enhance
collaboration among team members.
3 Regular Pull Requests
Encourage team members to review each other's work through pull requests,
fostering a culture of feedback and improvement.
Backup and Recovery
Regular backups of the Git repository safeguard against data loss and provide
security in case of unexpected events.
