How Git Commands Work

Git can seem confusing at first, but a few key concepts make it clearer:

There are 4 locations for your code:
- Working Directory
- Staging Area
- Local Repository
- Remote Repository (like GitHub)

Basic commands move code between these locations
- git add stages changes
- git commit saves them locally
- git push shares them remotely
- git pull fetches updates from others

Branching allows isolated development.

Concepts like git clone, merge, rebase enable collaboration.

Graphical tools like GitHub Desktop also help by providing visual interfaces and shortcuts.

While advanced workflows are possible, understanding this basic flow unlocks Git's power.

Linux Tip of the Day 💡🐧

If you want to clean empty directories, find command can make the job easy:

$ find . -type d -empty -exec rmdir -v {} +

The -type d option searches for directories, -empty select empty ones and -exec rmdir {} executes the rmdir command to delete them.

Docker is a popular technology that helps software developers build, package, and distribute applications. It uses containers to isolate and run applications, making it easy to move them between different environments. This simplifies the process of software development and deployment.

How does Docker Work?

Docker's architecture comprises three main components:

🔹 Docker Client
This is the interface through which users interact. It communicates with the Docker daemon.

🔹 Docker Host
Here, the Docker daemon listens for Docker API requests and manages various Docker objects, including images, containers, networks, and volumes.

🔹 Docker Registry
This is where Docker images are stored. Docker Hub, for instance, is a widely-used public registry.
