What is Git

Git is a distributed version control system that enables you to manage code changes efficiently in collaborative software development projects using the git command.

A committed change, also known as a git commit, can be applied in various scenarios, including implementing new features, fixing bugs, and more.

Git commits are essential for tracking code modifications, ensuring collaboration among team members, and maintaining a well-organized codebase.

Termomonlogy and Concept

    1. Default Brance:
      • Git:
        • Still “master”
        • Options for other default branch names
      • Github:
        • Default now “main” (new repos only)
        • Can be reset back to “maste
    2. Ignore files:
      • Git:
        • Is made in the file .gitignore

Initializes a new Git repository
specifically in a directory called "demo-one."
This means that Git will set up its version control system
in the "demo-one" folder 		git init demo-one
initializes a new Git repository with the name "demo-one"
and sets the default branch to "main." 		git init -b main demo-one
Displays information about the current state of your Git repository git status
Add all changes in the working directory to the staging area. git add .
Stage all changes, including new, modified, and deleted files git add -A
Commit all changes with a commit message. git commit -a -m "Commit message"
List all local branches in the repository git branch
Create a new branch named branch_name. git branch branch_name
Delete a specific branch (branch_name) after its changes have been merged. git branch -d branch_name
Rename the current branch to new_branch_name. git branch -m new_branch_name
List all local and remote branches. git branch -a
List all remote branches git branch -r
Create a new branch (new_branch) based on the current branch git branch -c new_branch
List all remote repositories associated with the current repository. git remote
Display more detailed information about the remote repositories, including their URLs. git remote -v
Add a new remote repository with the name "origin" and the specified URL git remote add origin
Remove the remote repository named "origin." git remote rm origin
Change Remote Push URL
( git remote set-url --push origin https://github.com/ripper079/referenceJS.git )
( git remote set-url --push originl origin git@github.com:ripper079/referenceJS.git )
 git remote set-url --push "remotename" "new_fetch_pull_url"
Change Remote Fetch/Pull URL
(git remote set-url origin https://github.com/ripper079/referenceJS.git )
( git remote set-url origin git@github.com:ripper079/referenceJS.gi t)
 git remote set-url "remotename" "new_fetch_pull_url"
Rename a remote repository from old_name to new_name git remote rename old_name new_name
Display information about a specific remote repository named "origin." git remote show origin
Fetch the latest changes from all remote repositories git remote update
Change the URL of the remote repository named "origin." git remote set-url origin
Display help information about the git remote command. git remote -h
CONFIG
This Git command sets the default branch name
for newly initialized repositories on your system.
In this case, it configures Git to use "main" as the default branch name. 		git config --global init.defaultBranch main
Display the current configuration settings for the repository. git config --list
Set the user name for your commits in the repository. git config user.name "Your Name"
Set the email address associated with your commits. git config user.email "your.email@example.com"
Set the global user name for all Git repositories on your system. git config --global user.name "Your Name"
Set the global email address for all Git repositories on your system. git config --global user.email "your.email@example.com"
Remove the user name configuration for the repository. git config --unset user.name
Remove the global user email configuration. git config --unset --global user.email
Set the default text editor for Git commit messages. git config core.editor "editor"
Set the default text editor for Git commit messages. git config core.editor "editor"
Enable colored output in the Git command-line interface. git config color.ui auto
