If you’re new to coding, or just want to brush up on your skills, this beginner’s guide is for you! In it, we’ll take you through the basics of Linux programming – what tools are available to you, how to use them, and how to create basic scripts.
What is Linux?
- Linux is a Unix-like operating system that employs a Linux kernel.
- Linux systems are used in a wide variety of environments, including servers, desktop systems, mobile devices and embedded systems.
- Linux is free and open source software released under the GNU GPL.
The Linux Kernel
Linux is a popular open source operating system that is used on a wide variety of devices, from servers to smartphones. Like most complex software, the Linux kernel is built from many smaller pieces. In this beginner’s guide, we will introduce you to the Linux kernel and show you how to code your first simple program.
Basic Commands in Linux
Linux commands are essential for coding and scripting. This guide covers some of the most common commands used in Linux.
linux commands
cd
- Change directory (location)
ls
- List files in directory, including subdirectories and files with Hidden or System attributes
cp
- Copy files (with the source file specified first)
mv
- Move files (with the source file specified first)
grep
- Search for a specific string inside a file or folders
cpio
- Create a backup of a file using cpio
Files and Directories
In this blog post, we will discuss the basics of files and directories in Linux. A file is a collection of data that can be stored on your computer. A directory is a special type of file that stores all of the files in a specific location on your hard drive. You can access files and directories by using the command line or by using the graphical user interface (GUI).
Shell Commands
Linux is an operating system that runs on servers, desktops and laptops. It is a Unix-based platform, meaning it is based on the Unix operating system. You can use the shell commands in this guide to get started with Linux coding.
Bash scripting
There’s a lot to know about computer programming, and one of the most basic languages is Bash. Bash is a command-line shell that you can use to automate tasks or write scripts. In this beginners guide, we’ll teach you how to code in Bash using commands you’re likely to encounter.
Systemctl Commands
Systemctl is a command-line utility for managing systemd units. In this guide, we’ll show you how to use Systemctl to start and stop services, check status, and more.
1. To start or stop a service using Systemctl:
# systemctl start service_name # systemctl stop service_name
2. To see the status of a service:
# systemctl status service_name
