Linux Architecture
Linux is a robust and versatile operating system that powers a significant portion of the computing world, from servers and embedded systems to desktops and mobile devices. In this blog post, we will take a closer look at the architecture that underlies the Linux operating system.
Kernel:
At the heart of Linux is the kernel, the core component that manages system resources, facilitates communication between hardware and software, and provides essential services. The kernel is the powerhouse of a computer's operating system, wielding complete control over every aspect of the system. It's the unsung hero behind the scenes! 💻
We Can't directly command to the kernel as it can understand the machine language so for that Shell helps to communicate to kernel also known as CLI.
Shell:
The shell is your interactive gateway to the operating system, translating user commands into a language the kernel comprehends. Think of it as the mediator, accepting human-readable instructions and making things happen. 🤖💬
Linux Shell Scripting:
Shell scripting is the art of creating programs run by a Linux shell. These scripts, often considered scripting languages, empower DevOps engineers to perform tasks like file manipulation, program execution, and text printing—all from the command line. 📜🚀
Introduction
Linux commands are powerful tools that allow users to interact with the operating system through the command line interface (CLI). In this article, we'll cover some basic Linux commands to help you navigate and perform common tasks.
🚀Basic Linux Commands
1.⚜️File Commands
2.⚜️Directory commands
mkdir dirName # make a new directory 'dirName'
mkdir .Newdir # make a hidden directory (also . before a file to make it hidden)
mkdir A B C D #make multiple directories at the same time
mkdir /home/user/Mydir # make a new folder in a specific location
mkdir -p A/B/C/D # make a nested directory
pwd #This command will display the full path to the current directory.
cd path_to_directory #change directory to the provided path
cd ~ or just cd #change directory to the home directory
cd - # Go to the last working directory.
cd .. # change directory to one step back.
cd ../.. # Change directory to 2 levels back.
Creating Nested Directories
To create nested directories, the mkdir command is employed. The -p option allows you to create parent directories if they don't exist.
This example creates a nested directory structure A/B/C/D/E. The -p option ensures that all parent directories are created, even if some of them are missing.
Conclusion
These basic Linux commands are just the tip of the iceberg. As you delve deeper into the world of Linux, you'll discover a plethora of commands and options to streamline your workflow.
