GIT is a distributed version control system that allows tracking code revision history, sharing codebases with collaborators, and merging collaborator code. It offers advantages like performance through object-based storage, security through integrity checks, flexibility through branching and tagging, and open source acceptance. Potential disadvantages include a steep learning curve and slower performance for binary files. Common GIT commands include init, clone, status, add, commit, pull, push, branch, checkout, merge, and log.

GIT
GIT is one of the distributed version control systems that helps in
? Tracking code revision history
? Sharing codebase with collaborator
? Merging collaborators code with your code

GIT: ADVANTAGES
? Performance: In GIT Code changes can be easily committed, compared and merged. This
is because GIT is object based and object formats of GIT repository use several
combinations of delta encoding to store metadata objects and directory contents.
? Security: GIT maintains the integrity of source code. File contents, as well as the
relationship between files/directories, are secured via an algorithm which protects the
code and code history against accidental damage.
? Flexibility: GIT is uniquely designed to support tagging and branching operations and
store each activity carried out by the user as an integral part of “change” history.
? Open Source: GIT is a widely used open source version control with acceptance for more
than 10 years. It is a widely-accepted system owing to its universally accepted usability
and performance standards.

GIT: DISADVANTAGES
× For doing a small operation(s), a lot of commands are needed in GIT.
× For Binary file like images, on-text files GIT becomes slow.
× Bad command line syntax which is arbitrary and inconsistent.
× For a beginner, it’s a steep learning curve to learn so many commands and it’s
parameters.

GIT: COMMANDS
? Init: Used to initialize a git repository from an existing directory of files
$ git init
? Clone: Used to get a copy of the project into your local machine
$ git clone <githuburl>
? Status: Used to view the status and changes of the directory on which you are
working on and staging area.
$ git status

GIT: COMMANDS
? Add: Used to add files and directories to git staging areas before you can commit
them.
$ git add my_new_file.txt
? Commit: Used to record a snapshot of git’s staging area
$ git commit -m “Add three files“
? Reset: Used to undo all changes and commits
$ git reset –soft HEAD^

How to store large binary files in git repositoriesMatt Aunger

This document discusses 7 approaches for handling large binary files in Git repositories: 1. Git Annex stores file contents separately from the repository and uses symlinks to reference them. Allows sharing between teams but requires learning new commands. 2. Git Large File Storage (LFS) stores file blobs on a separate server using pointers. Supported by GitHub but requires a custom server. 3. Git-bigfiles aimed to backport large file handling directly into Git but the project is abandoned. 4. Git-fat and Git-media work similarly to LFS using filters and storing files on remote servers like S3. They are older and less actively developed. 5. Git-bigstore and Git

Change history with Gitgsterndale

Git allows developers to integrate changes across branches through merging or rebasing. Merging joins development histories together but can lead to merge conflicts and "merge madness". Rebasing forwards local commits to the updated upstream head, avoiding unnecessary merge commits and keeping a linear history. Developers can use Git's interactive rebase mode to reorder, edit, drop, squash, or split commits when changing a branch's history before integrating it into another branch.

Git: Git'ing the BasicGerald Villorente

Nyc Code Camp 2010 Git And Githubjptoto

Git is a distributed version control system (DVCS) created by Linus Torvalds in 2005 as an alternative to BitKeeper after its free-of-charge status was revoked for Linux kernel developers. Unlike typical SCMs that track file changes, Git treats each commit as a full snapshot of the project and only stores file differences between commits. This makes Git operations like branching and merging very fast and efficient. Git allows developers to work offline and each local repository contains the full project history. GitHub is a popular hosting service for Git repositories that allows for collaboration and code review. While Git can be used as a valid SVN client, it is best to avoid rewriting history when using Git with SVN to prevent issues with other team

3. GIT: ADVANTAGES ? Performance: In GIT Code changes can be easily committed, compared and merged. This is because GIT is object based and object formats of GIT repository use several combinations of delta encoding to store metadata objects and directory contents. ? Security: GIT maintains the integrity of source code. File contents, as well as the relationship between files/directories, are secured via an algorithm which protects the code and code history against accidental damage. ? Flexibility: GIT is uniquely designed to support tagging and branching operations and store each activity carried out by the user as an integral part of “change” history. ? Open Source: GIT is a widely used open source version control with acceptance for more than 10 years. It is a widely-accepted system owing to its universally accepted usability and performance standards.
