Description
As part of this course, you will learn most of the important Linux commands that can come in handy while working in Linux-based environments.

Here are the high-level details of the Linux Commands that are covered as part of this hands-on course.

You will get started by having an appropriate environment to practice. Windows users can set up Ubuntu 20.04 using wsl.

Once the environment is ready, you will understand how to get started with basic Linux Commands.

The most commonly used command in Linux is ls. It is used to list the files. We will see different variations of ls by going through all the relevant arguments.

One of the powerful Linux commands and also my favorite is "find". It helps us to filter the files and directories based on name, type, modified time, etc. You will learn how to use the find command effectively from the perspective of finding the files based on the criteria.

As we understand how to get details related to files and folders in Linux, we will go through the details related to previewing the data in files using important Linux commands such as cat, tail, more, etc. Also, we will review Linux commands such as cut, sort, uniq to process the data. All these commands are typically used against text files.

After going through details related to ls, find commands as well as commands related to processing data in files, we will walk you through the details related to file and folder properties in Linux. You will get an overview of commands such as useradd, userdel, chmod, etc which are typically associated with file permissions.

One of the key aspects related to files and folders is to manage them effectively. We will go through the details about managing files and folders using Linux commands such as cp for copy, mv for move or rename, rm for delete or remove, tar to build uncompressed as well as compressed tar balls. Also, you will get a taste of the awk command to automate some of the common tasks such as reorganizing the files based on patterns.

The core components of a computer are nothing but CPU, Memory, and Storage. In this section or module, you will be learning Linux commands such as lscpu to get CPU details, free to get memory details, and then df and du to get storage details.

At times, we need to make sure the data is in files as well as codebase to troubleshoot the production issues or bugs in QA. In this section, you will learn how to use the Linux command called diff to compare files and folders and review the differences.

Environment Variables are the ones that can impact the sessions logged in by users in Linux. As part of this section, you will be learning details related to Variables, Environment Variables. Also, you will understand how to list all the Environment Variables using Linux commands such env, and how to get a value of a Variable or Environment Variable using the Linux command echo. On top of these things, you will also learn all important aspects related to one of the most important Environment Variables called PATH.

As we gain a decent amount of knowledge related to Linux commands using a single server, it is time for us to explore other important commands such as ssh, scp, pssh, pscp, etc which require more than one Linux System or Server. Also, we need to go through basic networking concepts. To learn commands to interact between the servers as well as to understand basic networking concepts, we will get started with AWS to provision Ubuntu-based virtual machines. These Virtual Machines will be used in the subsequent sections to learn the concepts mentioned earlier as part of this bullet point.

Once we go through the details about getting started with AWS, we will focus on learning all key concepts related to SSH such as sshd daemon, updating ssh config files, and restarting sshd using systemctl or service command. Also, we will go through the details related to passwordless login and also ability to run commands remotely via ssh. We will also understand how to set up parallel ssh and then run commands on multiple Linux systems in parallel.

To be comfortable with learning in a Linux environment, it is very important for one to understand key concepts such as different types of IP Addresses, Port Numbers, relationships between applications and databases with ports, etc. In this section, we will go through all important networking concepts using apache2, MongoDB, etc.

Once we are comfortable with SSH, it is time for us to use tools such as scp which uses ssh under the hood to copy files and folders between the Linux Systems. We will also explore parallel scp to copy files in parallel to multiple target systems from one source system. Also, we will go through the details related to speeding up the copy using different techniques which include submitting multiple scp commands using nohup.
