Yeah, as soon as you hit that man page, you're going to want to throw Linux out. And you should, because everything in Linux is that irrational and exasperating. From the insane file structure, to the repositories that never seem to have what you need, to the enraging default file permissions, to the inability of anyone in the known universe to explain the many errors you will get (hint: they ALL mean, "go back to Windows, silly boy), Linux is an exercise in constant frustration. You will spend countless hours fighting and fighting to bring your Linux experiment up to a minimal level of function, only to realize that a minimal level of function is all Linux will ever deliver. Just throw it out at the start and save yourself the frustration.

Feb 2020.. Just switched to Linux Mint 19.3. Cinnamon from ( u know, the usual suspect!) Windows 7.. I'm inverted to computers and learning, as of now.. Linux is not complicated at all, actually It's Easy, Once you get to Know It !!! Good Video, though.

If you want to exit man pages, remember to press Q BEFORE you throw the computer out the window, not after.

Hi Eli, can you please share me one link where I will be able to get get all the videos as it is tough to watch all the videos identically? I watch all your videos and I follow only you for Linux. You have described all the stuffs very clearly. If possible, please share your contact number so that I could ask questions from you on whatsapp.

What is your justification for using the term LUI? No meaning, origin, nor fields of use are readily available from an internet search for LUI. CLI (command line interface) is a common term, used in both IT and software development.

Thanks Eli. You are a great instructor. The admin protocols I learned about Linux came from studying under managers. I wanted to start from the basics, and you have done that. Thanks keep doing what you are doing bro.

how does continued updates equate to an OS being crap? I've seen Linux distros patch their software almost as frequently as Windows. So by their logic Linux is also crap. "oh Linux doesn't have as many security vulnerabilities as Windows does, so it's safer" that's crap, if I were a hacker wanting to send malware to a bunch of computer users I would hedge my bets and write said malware for Windows because Windows has the larger install base. That isn't to say there aren't any for Linux. And honestly I've seen more web and database server exploits than anything. Which are individual services running on Linux. And that's not even talking about VMs running on the Linux platform that are running Windows servers, among other things. Linux has it's place in the IT world, Windows has it's place. stop pretending one is better than the other overall because of some arbitrary attributes, that are false. I personally love Linux in web, file, db, and vm hosting roles.

This is really good. I have followed and watched your videos and it's been really informative and useful to me. However, I would like to ask you for a favor. Can you make a video of installing active directory, DHCP and DNS in Linux server? I really want to know how it works. Secondly, in an enterprise environment, what server is used the most, Windows server or Linux server?

Thanks! It's great you provide the related idea in Windows… I'm sure many people are good in Windows, but just new to Linux.
May be a great version of training is "Linux for Windows users" (or may be you already have something..) Keep up the great work!!

hey eli, some of the info e.g. explaining the sudo is really great but you keep repeating that this is not windows again and again :)) sometimes the fodder between pieces of applicable info is a bit too much, it's nice that it's not totally dry instruction but after two other videos you keep reminding us this is different from windows 🙂

Login as root –> sudo bash

Also, man pages do not work by default.
Use –> sudo apt-get install man-db

I started this tutorial a little confused but I am one for analogies and I found the use of Windows analogies very helpful thank you because ten minutes in I was going to quit but glad I didn't. What I don't get is using my desktop Mint command like top worked with out sudo in front of them and I must find out what is meant by teh ROOT directory.
