Linux is an open-source operating system kernel that serves as the foundation for numerous operating systems known as Linux distributions. It was developed by linus torvalds.
In DevOps (Development and Operations), Linux plays a crucial role due to its command-line interface (CLI), a vast collection of tools, and robust networking capabilities. Here's how Linux is commonly used in DevOps:
Server Infrastructure
Automation and Scripting
Configuration Management
Containerization and Virtualization
Monitoring and Logging
Security and Access Control
Continuous Integration and Continuous Deployment (CI/CD)
Command
Description
ls
lists files and directories in the current working directory
cd
changes the current working directory
pwd

mkdir
creates a new directory
touch
creates a new file
rm

- How to check the present working Directory?
To check the present working directory in Linux, the steps: open a terminal, then type a cmd 'pwd' will prompt the present in which directory we are located.
2. List all the files or directories including hidden files.
To list all the files and directories, including hidden files, in a directory or files, you can use the ls command with the -a option. Hidden files and directories are denoted by a dot (.) at the beginning of their names
3. Create a nested directory A/B/C/D/E
To create a nested directory you can use the following command.
mkdir -pv A/B/C/D/E
Here, the "-p" flag will create the parent directory.
To check whether the directories are created are not, you can check with the below command.
ls -R A/
Summary:
Linux provides a powerful and flexible platform for DevOps practitioners, enabling them to automate processes, manage infrastructure, and streamline software development and deployment. Linux makes work easy with simple commands and provides more security.
