Hello DevOps enthusiasts! As I wrap up my journey with Linux, Git, and GitHub, Iโm excited to share my comprehensive cheat sheet. Itโs a labor of love, packed with the commands and tips Iโve gathered. Letโs dive in! ๐
Linux Command Line Essentials ๐ง
Linux is the cornerstone of many IT infrastructures, and here's a more extensive list of commands that I've found invaluable:
File Operations
ls- Lists files and directories.ls -lfor detailed view,ls -afor hidden files.
touch- Creates a new file.cp- Copies files and directories.cp source destination.
mv- Moves or renames files and directories.rm- Removes files or directories.rm -rfor recursive deletion.
Directory Navigation
cd- Changes the current directory.pwd- Displays the path of the current directory.mkdir- Creates a new directory.
System Information
uname- Shows system information.top- Displays real-time system stats.df- Shows disk space usage.du- Shows file space usage.
Network Operations
ping- Checks network connectivity.ifconfig- Configures or displays network interface parameters.ssh- Connects to a remote server securely.
File Permissions
chmod- Changes file permissions.chown- Changes file owner.
Git Command Reference ๐ฟ
Git, the distributed version control system, has been my faithful companion in tracking changes and collaborating on code. Here's a detailed list of Git commands:
Getting Started
git init- Initializes a new Git repository.git clone- Clones a repository into a new directory.
Basic Snapshotting
git status- Shows the working tree status.git add- Adds file contents to the index.git commit- Records changes to the repository.
Branching and Merging
git branch- Lists, creates, or deletes branches.git checkout- Switches branches or restores files.git merge- Merges two or more development histories together.
Sharing and Updating Projects
git push- Updates remote refs along with associated objects.git pull- Fetches from and integrates with another repository.
Inspection and Comparison
git log- Shows the commit logs.git diff- Shows changes between commits, commit and working tree, etc.
GitHub Essentials ๐
GitHub is where my code lives and breathes. It's a platform that complements Git perfectly. Here's a quick rundown:
Repository Management
Create Repository: New project home.
Fork Repository: Make a copy for your own.
Star Repository: Mark your favorite.
Issue Tracking
Open Issue: Start a discussion or report a bug.
Close Issue: Resolve and close discussions.
Pull Requests
Create Pull Request: Propose your changes.
Merge Pull Request: Combine changes into the main project.
๐จ Design and Creativity in My Cheat Sheet: Iโve color-coded sections for quick navigation and included icons for visual appeal. Tips and tricks are in a separate column for advanced users, and each command is accompanied by a brief description and usage example.
๐ Reflections: Building this cheat sheet was not just educational but also a creative journey. Itโs a resource that Iโll keep updating and referring to. Iโm thrilled to share it with the community and hope it proves as useful to others as it has to me! #DevOps #LinuxCommands #GitCheatSheet #GitHubGuide #TechTips ๐๐
