Continuing the #90daysofDevOps challenge by the #TWS community. We will explore Linux and why is it important for DevOps.

Introduction

Linux is an operating system that acts as an interface between the user and the system. It is free and open source(can be modified).

Some of the key features of Linux are:

  • Stable and secure

  • Flexible and customizable

  • Widely supported

  • Powerful command-line interface

  • The active community of developers

There are many different flavors (types) of Linux, each with its strengths and weaknesses. Some popular flavors of Linux include Ubuntu, Fedora, and Debian.

Importance of Linux in DevOps

As explained about the practices in DevOps in the last article the focus is primarily on automation, quality, continuous monitoring, and testing. Linux is a popular operating system for DevOps because it is free, open-source, and stable. Linux is also very customizable, which makes it a good fit for the different needs of different organizations.

Here are some examples of how Linux is used in DevOps:

  • Infrastructure automation: Linux can be used to automate the deployment and configuration of infrastructure resources. This means that DevOps teams can use Linux to quickly and easily set up new servers and applications.

  • Continuous integration and continuous delivery (CI/CD): Linux is a popular choice for running CI/CD pipelines. CI/CD pipelines are used to automate the testing and deployment of new code. This helps to ensure that new code is always tested and deployed consistently and reliably.

  • Containerization: Linux is the foundation of containerization technologies like Docker and Kubernetes. Containerization is a way of packaging software so that it can be easily deployed and managed. Linux is a good choice for containerization because it is a stable and reliable operating system that can be easily scaled to meet the needs of large organizations.

Overall, Linux is an important part of the DevOps toolkit.

Linux commands

Linux commands are instructions that you can give to your computer to perform tasks. They are entered into the command line, which is a text-based interface that allows you to interact with your computer directly

Some of the basic Linux commands:

  • ls: This command lists the files and directories in the current directory.

  • cd: This command changes the current directory.

  • pwd: This command prints the current working directory.

  • mkdir: This command creates a new directory.

  • rmdir: This command removes an empty directory.

  • cp: This command copies a file or directory.

  • mv: This command moves or renames a file or directory.

  • rm: This command deletes a file or directory.

  • man: This command displays the manual page for a command.

  • cat: This command displays the contents of a file.

  • echo: This command prints text to the terminal.

  • grep: This command searches for a pattern in a file.

  • sort: This command sorts the lines in a file.

  • uniq: This command removes duplicate lines from a file.

  • wc: This command counts the lines, words, and characters in a file.

In the next blog, we will try to perform simple tasks based on Linux commands
