Get Well Acquainted with Linux: A Comprehensive Note（linuxnote）
When it comes to operating systems, Microsoft Windows is undoubtedly at the helm. Most home computer users and most businesses use Windows as their primary operating system. But, beneath the limelight, an entirely different ecosystem exists – one that is seen in web servers, cloud services and everywhere else in-between. This is the ecosystem of the Linux operating system, which is renowned for its power, stability, and security.
As a programmer, it’s always wise to get well acquainted with Linux in order to gain an understanding of its inner workings. Here is a comprehensive guide on getting to grips with Linux:
1. Install a Linux distro: First, you need to install a Linux distro (or distribution) to start using Linux. There are many different distributions, such as Ubuntu, Fedora, and CentOS, so choose one that best suits your needs.
2. Get to grips with the command line: The command line constitutes the backbone of Linux. Instead of GUI (Graphical User Interface), you will be using the CLI (Command Line Interface) to operate Linux. Hence a good grasp of the terminal becomes essential. To take things a step further, learning Bash shell scripting would be great.
3. Familiarize yourself with system administration: Whether it’s setting up a new machine, managing accounts and permissions or upgrading a system, knowledge of the basics of system administration can come in handy down the line.
4. Understand the file system structure and permissions: Knowing the difference between the various Linux file system types like EXT3, EXT4 and so on, and learning the fundamentals of the file system structure (like /usr, /bin etc), helps to understand what goes where and why. Additionally, permissions play a big role in security while using Linux, so familiarizing yourself with these is necessary.
5. Mess around with applications: Linux is ripe with amazing tools and applications that can get your job done more quickly and efficiently. Messing around with these applications and seeing what works for you can help you use Linux like a pro.
When it comes to programming, Linux is the wild child – Powerful, secure and stable. Gaining even a basic familiarity with its concepts can go a long way in propelling your growth as a programmer.
