Git
Introduction
This cheat sheet provides a quick reference for some common Git commands and concepts. Git is a distributed version control system used for tracking changes in code repositories.
Git Concepts
Repository
A Git repository (repo) is a directory that contains all the files, history, and metadata for a project.
Create a new Git repository:
git init
Clone an existing repository:
git clone repository_url
Commit
A commit represents a snapshot of your project at a specific point in time.
- Create a new commit:
git commit -m "Commit message"
Branch
A branch is a parallel line of development in a Git repository.
Create a new branch:
git branch branch_name
Switch to a branch:
git checkout branch_name
Create and switch to a new branch:
git checkout -b new_branch_name
Remote
A remote is a reference to a repository hosted on a remote server (e.g., GitHub, GitLab).
Add a remote repository:
git remote add remote_name repository_url
List remote repositories:
git remote -v
Pull
Pulling fetches changes from a remote repository and integrates them into the current branch.
- Pull changes from a remote repository:
git pull remote_name branch_name
Push
Pushing sends your committed changes to a remote repository.
- Push changes to a remote repository:
git push remote_name branch_name
Merge
Merging combines changes from one branch into another.
- Merge a branch into the current branch:
git merge branch_name
Conflict
A conflict occurs when Git can't automatically merge changes.
- Resolve conflicts by editing the conflicting files and then committing the changes.
Git Command-Line
Check the status of your working directory and staged changes:
git status
View the commit history:
git log
Add changes to the staging area:
git add file_name
Unstage changes from the staging area:
git reset file_name
Discard changes in your working directory:
git checkout -- file_name
Rename a file:
git mv old_file_name new_file_name
Delete a file from the repository and working directory:
git rm file_name
Show the differences between commits or branches:
git diff
