What you would learn in Linux Shell Commands for Absolute Beginners using Ubuntu 20x course?
As part of this class, you will master the majority of the essential Linux commands that could help you work in Linux-based systems.
These are the top-level information on the commands in Linux taught in this course.
It is essential to start by having the right environment to learn. Windows users can install Ubuntu 20.04 with us.
After the environment is in place, it will be easier to start using simple Linux commands.
The most popular method on Linux is the ls command. It allows you to list the files. We can see various variants of ls when we go through all the arguments relevant to the task.
One of the most potent Linux commands, and my favorite command, is " find." It lets us sort directories and files by name and type, modify time, etc. Learn how to utilize the find command efficiently from locating the documents based on the requirements.
Once we know how to access information related to the folders and files on Linux and other operating systems, we'll look at the steps to preview data within files by using essential Linux commands like cats, tail, etc. Additionally, we will go over Linux commands like cuts, sort, uniq to perform the processing of the data. These commands are generally employed against text files.
After going over the information about ls and finding commands and commands that process the data contained within files, we'll go over the details regarding folder and file property settings in Linux. We will provide an overview of commands like the useradd, userdel, chmod, and others usually used to control permissions on files.
One of the most critical aspects of managing the folders and files is how to manage them effectively. We will discuss the specifics of managing folders and files using Linux commands like the cp command to copy files, the mv command to transfer or change the name, rm for deletion or removal, tar to make uncompressed, and compressed ball tar. In addition, you'll experience how to use the awk command, which automates the most common tasks like reorganizing files according to patterns.
The essential components of a computer comprise only CPU Storage, Memory, and CPU. In this section or module, you will be learning Linux commands, such as the lscpu command to obtain CPU information, free to find memory details, and the df or du to obtain storage information.
Sometimes, we have to ensure that the information is present in the file and the codebase to identify production issues or problems in the QA. In this article, you will be taught how to utilize the Linux command known as diff to examine the folders and files and the distinctions.
Environment Variables are those which can affect sessions logged by users on Linux. In this section, you'll learn more about Variables and Environment Variables. You will also learn the procedure for listing all Environment Variables with Linux commands like env and env, as well as how to determine the value for a Variable and an Environment Variable by using an echo command in the Linux Command echo. In addition to this, you will also be taught the essential aspects of PATH, one of the more crucial Environment Variables called PATH.
When we've gained a significant understanding of Linux commands by using just one server, it's now time to investigate other crucial commands like SSH, scp Pssh, pscp, and others that require at least one Linux system and Server. We also need to explore the basics of networking. To learn commands to communicate between servers and to grasp the basics of networking, We will begin using AWS, which allows Linux-based Virtual machines. Virtual Machines will be utilized in subsequent sections to study the concepts discussed in the previous bullet point.
When we've gone over the steps, to begin with, AWS, We will concentrate on understanding the fundamentals associated with SSH, like the sshd daemon and updating the ssh configuration files, and then restarting the sshd daemon by using the systemctl or service command. Additionally, we will look at the information about passwordless login and the capability to run commands remotely using the ssh protocol. We will also know how to configure parallel ssh to execute commands across multiple Linux platforms in parallel.
To feel comfortable learning in a Linux environment, it's essential to comprehend the most fundamental concepts like different kinds of IP addresses, Port Numbers connections between applications, databases using ports, etc. In this article, we will explore the key concepts in networking with the help of Apache2, MongoDB as well as other databases.
Once we're comfortable using SSH and its capabilities, we can start using tools like SCP that uses ssh beneath the hood to transfer folders and files between Linux Systems. We'll also be exploring the possibility of using parallel SCP to transfer files to multiple systems from a single source system. We will also discuss the specifics of speeding the copy using various techniques, including submitting multiple scp commands using the nohup command.
