About the course

You came here looking for Linux training built for a network engineer,

 not for a software developer or a system administrator. That difference matters a lot. A developer needs Linux to write and run code. A system administrator needs Linux to keep servers running. You need Linux because every modern network device runs on it, every controller talks to it, and every automation script depends on it. This course was designed only for your situation.


The why behind this course is simple. 

Vishnu Dutt spent 19+ years at Cisco. During those years he saw a slow but unstoppable shift. Routers stopped being closed black boxes. Switches started running Linux under the cover. Controllers like SD-WAN vManage and SD-Access DNAC are nothing but big Linux machines. Network automation tools like Ansible, Python libraries, and EVE-NG itself all run on Linux. The engineers who picked up Linux early moved into senior roles. The ones who avoided Linux got stuck in level one support. This course brings everything Vishnu learned in those years into 12 focused hours, so you do not waste time on Linux topics that have nothing to do with your daily work.


Why is this offered as a Package and not just a single course? 

Because more than 15000+ learners across 100+ countries told us the same thing again and again. Some days they want to learn in English, because the official documentation, the certification exams, and the global interviews all happen in English. Other days, especially after a long shift, they want to hear the same concept in Hindi, because Hindi feels lighter on the brain. A learner from Mumbai, Delhi, Bangalore, or a small town in Bihar deserves both options. So the Package gives you both Hindi and English versions of every lesson, in one price, under one login. You switch languages whenever you want, without paying twice.


The course follows a strict why first approach. 

Before any command is typed, you will know why that command exists. Before any concept is explained, you will know the problem that concept was invented to solve. For example, before learning chmod, you will know why three permission classes were created in the first place. Before learning the ip command, you will know why the older ifconfig command was replaced. This is how Vishnu teaches. He believes that if you understand the mind of the person who built a concept, the concept becomes very easy to remember. Memory based learning fades in two weeks. Why based learning stays for years.


The course is also built around real network engineer use cases. 

You will not waste hours on Linux topics that you will never touch. You will not learn how to compile a kernel. You will not learn desktop themes. Instead, you will learn the file system layout you will see on a Cisco controller. You will learn the permission model that protects production config files. You will learn the user and group commands that decide who can change what. You will learn the networking commands that you will actually type during a real production incident. And you will learn the basics of bash scripting and software management, so you can start automating small daily tasks from day one.


Every lab in this course runs on EVE-NG. 

This is the same lab tool that the global networking community uses for practice. You will not just watch a screen. You will redirect output, chain commands with pipes, break permissions on purpose and then fix them, and run real commands on a real Linux box. By the end of Lesson 6 alone, the command line will feel as natural as the Cisco IOS prompt.


This course is also a true foundation course.

 You do not need any Linux background to start. You do not need any pre course material. If you are also new to networking, you can pair this course with CCNA for Know Nothing Learner or the Hindi equivalent Be Job Ready in Computer Networking. If you already know networking and want to go further after Linux, the next natural step is Python from Scratch followed by Network Automation from Scratch.


What do you actually get when you buy this Package? You get 12 hours of lessons in both Hindi and English. You get every lab demo on EVE-NG. You get a completion certificate from BridgeWhy. You get a teacher who answers questions personally. And you get the same teaching that has helped thousands of engineers cross over from pure networking into networking plus automation. The job market today rewards engineers who know both sides. This Package puts you on the right side.

If you also want to strengthen your protocol knowledge alongside Linux, look at Routing Fundamentals, Switching Fundamentals, BGP from Scratch, and SD-WAN from Scratch. When you reach the interview stage, the Interview Preparation Series will sharpen your answers. You can read more about the teacher and the teaching style on the About Us page.

What you will learn


Lesson 1: Why behind Operating System
Why does an operating system even exist? Hardware understands only zeros and ones. You think in commands like "open this file" or "send this packet." Someone had to invent a layer that translates between you and the hardware. This lesson explains that layer, the role of the kernel, and where Linux sits inside the whole picture.

 Lesson 2: Let us Start Linux
Most engineers fear the Linux command line because they never saw the first few commands explained slowly. This lesson removes that fear once and for all. You will boot a Linux machine, see the first prompt, type your first commands, and understand what the shell is actually doing behind the scenes.

Lesson 3: Linux File System Part 1
In Linux, everything is a file. Devices are files. Network interfaces are files. Even running processes appear as files. This sounds strange at first, but it is the most powerful idea in Linux. This lesson walks through the standard directory layout, /etc, /var, /home, /usr, and explains why this exact layout exists.

Lesson 4: Linux File System Part 2
Knowing the layout is not enough. You must also move through it, search inside it, and link files in clever ways. This lesson covers absolute and relative paths, the different file types you will meet, and the real difference between soft links and hard links, with a clear explanation of when to use which.

Lesson 5: File Permissions and Operations
A production network device runs live customer traffic. One wrong write to a config file can drop a customer link. Linux permissions exist to stop that mistake from ever happening. This lesson explains read, write, and execute, the three classes of owner, group, and others, and the commands chmod, chown, and chgrp.

Lesson 6: Lab 1 — Redirection, Pipes and File Permissions
Reading theory builds short term memory. Doing labs builds the muscle memory that survives in a real interview or a real outage call. This EVE-NG lab forces you to redirect command output into files, chain multiple commands with pipes, and break and fix permissions on purpose. By the end, you will trust your own hands.

Lesson 7: Concept of Users and Groups Part 1
A Linux machine is almost never used by only one person. Multiple engineers log in, run scripts, and own different files. Without users and groups, this would be total chaos. This lesson explains why /etc/passwd, /etc/shadow, and /etc/group were split into three separate files, and what each one stores.

Lesson 8: Concept of Users and Groups Part 2
Creating a user is the easy part. The real skill is knowing what powers that user has, and how to limit those powers safely. This lesson covers useradd, usermod, the sudo command, and the clear difference between sudo and su, so you can give the right level of access to the right person.

Lesson 9: Networking in Linux
Every modern controller, every cloud router, every SD-WAN headend, and every SD-Access fabric node runs Linux under the cover. The commands you learn here are the same commands you will type on production gear during a real incident. This lesson covers the ip command, interfaces, routes, ARP, ping, traceroute, and basic tcpdump.

Lesson 10: Bash Scripting and Software Management
A network engineer who can write a small bash script can do in five minutes what others do in five hours. Software management decides which tools you can install on a box, and which version you receive. This lesson covers variables, loops, if conditions, simple scripts, and the package managers apt, yum, and dnf.

Frequently asked Questions


What does this course actually cover?

The course covers 10 lessons over 12 hours. It begins with the why behind an operating system, then moves into Linux basics, the Linux file system, file permissions, redirection and pipes, users and groups, networking in Linux, bash scripting, and software management. Every topic is taught why first, and every lab demo runs on EVE-NG.

Why is this course made only for network engineers?

A generic Linux course wastes your time on topics like desktop themes, kernel compilation, and developer toolchains. A network engineer does not need those. You need the file system, permissions, users, groups, networking commands, and small scripts. This course gives you only what helps your daily work as a network engineer.

How is this course different from a free Linux tutorial on YouTube?

Free tutorials usually teach commands without context. They tell you what to type, not why that command exists. This course flips that. Every concept starts with the why. You will not just memorize commands. You will understand the design decisions behind them, which means you can answer interview questions and handle new problems on your own.

Will this course teach me Linux from absolute zero?

Yes. The very first lesson is "Why behind Operating System." You do not need any prior Linux exposure. You only need a working computer and the willingness to follow along on EVE-NG.

Does this course cover advanced Linux topics like kernel compilation or LFCS exam content?

No. This course stays focused on what a network engineer actually uses on the job. Kernel compilation, advanced systemd internals, and full LFCS exam prep are not part of this course. If you want those topics later, you can move into other dedicated Linux courses after finishing this one.

Do I need any prior Linux knowledge?

No. The course assumes zero Linux background. The first lesson explains operating systems before any Linux command is typed.

Do I need to know networking before starting this course?

Not strictly. The Linux concepts in lessons 1 to 8 work even without a networking background. But for Lesson 9 (Networking in Linux), some basic understanding of IP, routes, and ARP will help. If you are new to networking, you can take CCNA for Know Nothing Learner alongside this course.

Why is this called a Package?

The Package bundles both the Hindi and the English versions of the same course into one purchase. You get one login that opens both versions. You can watch the same lesson first in Hindi and then in English, or pick the version that fits your mood and energy on a given day.

Can I watch only the Hindi version or only the English version?

Yes. If you only want one language, you can buy that single language course separately. But most learners find that switching between Hindi and English on tough topics speeds up their learning. That is why the Package usually gives better value.

Are the Hindi and English versions exactly the same lessons?

The structure, lab demos, and lesson order are the same. The teaching language is different. The Hindi version uses Hinglish, which means English script with Hindi sentence flow and English technical terms. The English version uses simple international English.

Do I get a certificate after completing this course?

Yes. You receive a completion certificate from BridgeWhy after finishing the course.

Is this certificate accepted by employers?

The certificate proves you completed structured training. Employers value the skill more than the certificate, and this course teaches you the skill. When you walk into an interview and explain Linux concepts in your own words, the certificate becomes a useful supporting document.

Will this course help me in network engineer interviews?

Yes. Interviewers commonly ask network engineers about file permissions, the ip command, the difference between sudo and su, redirection, and small bash scripts. This course covers all of these in depth, why first. For deeper interview practice, pair it with the Interview Preparation Series.

Which Linux interview questions will I be able to answer after this course?

Examples include: what is the difference between a hard link and a soft link, how does chmod 755 work, what does sudo do under the hood, why was ifconfig replaced by the ip command, how do you find which process is using a port, how do you redirect both stdout and stderr to a file, and how do you write a simple loop in bash.

What lab tool is used in this course?

All demos use EVE-NG. EVE-NG is a popular network emulation platform that lets you run real router, switch, and Linux images on a single laptop or server.

Do I need to install Linux on my own laptop?

You do not need to install Linux on your main laptop. You can follow along on EVE-NG. If you want extra practice, a free VirtualBox or VMware Workstation Player setup with Ubuntu also works. Vishnu shows the steps in the early lessons.

How long do I get access to the course after buying?

ccess depends on which plan you pick. BridgeWhy offers 3 Month Access, 1 Year Access, and Lifetime Access. Most working engineers pick Lifetime Access because Linux skills stay useful for many years.

Can I watch the course on mobile and laptop both?

Yes. The BridgeWhy platform works on both mobile and laptop. You can start a lesson on your laptop at home and continue on your phone during a commute.

Can I download the videos for offline viewing?

The videos stream from the BridgeWhy platform. Streaming protects the content and keeps it updated when Linux changes. You can watch any lesson as many times as you want during your access period.

Who is the instructor?

The instructor is Vishnu Dutt, founder of BridgeWhy. He has 19+ years at Cisco and has trained 15000+ learners across 100+ countries. His teaching style is strict why first.

Can I ask questions to the instructor?

Yes. BridgeWhy has a question and answer channel where Vishnu and the team answer learner questions. You are not learning in silence.

After this Linux course, what should I learn next?

Python from Scratch and Network Automation from Scratch are the natural next steps. Linux gives you the operating system layer. Python gives you the language. Network Automation puts both to work.

Is this course enough to start network automation?

This course gives you the Linux foundation that automation depends on. You will not start writing full automation playbooks from this course alone, but you will be able to follow any automation tutorial without getting stuck on basic Linux commands.
