Linux for Hackers // EP 1 (FREE Linux course for beginners)

if you want to become a hacker you need to know linux it's a required foundational skill it's actually a prerequisite to doing anything and hacking like you have to know it so that's why in this series i'm going to teach you linux welcome to my linux for hackers series now while the series is linux for hackers most of what i'm covering is linux for everyone and i do mean everyone if you're nit or anything you need to learn and know linux this series will teach you the linux foundations you need to start hacking and we're not going to waste any time like you're going to start using linux right now i'm not kidding like right this moment in your browser check the link in the description you're getting access to a free linux lab thanks to my partnership with hack the box academy they're actually the official sponsor of this entire series so let's go let's get you using linux right now and by the way i'm having my two oldest daughters do the same thing you ready to start hacking no clue you ready start hacking sure they are ten and seven they're signing up for hack the box academy so if you're thinking man i can't learn linux that's too hard bullcrap yes you can let's go right now so once you've clicked the link and you signed up which by the way you should this entire series will use this lab so do it you can go through the introduction or just click skip like i am no big deal now notice one thing real quick right under your username you'll have 30 of whatever the junk that is those are cubes cubes are what you need to unlock whatever course you want to take through hack the box academy you can also purchase more but hey we've already got 30 we're good so next click on modules and then all modules i'm going to scroll down just a bit until i see linux fundamentals right here it costs 10 cubes we got 30. we're good we're going to click on unlock but real quick before you do that notice this right here what this plus 10 means is that if we finish this linux fundamentals course like we actually complete it hack the box academy will give us 10 cubes back so it's basically free as long as you do it what you're going to right not a big deal so let's click on it click on unlock yes let's do this thing and let's not waste any time let's click on start right now and on this page what we're going to do is scroll all the way to the very very bottom all the way here until you see this your workstation this is your linux box let's go ahead and click on start start instance coffee break perfect time ah that's good stuff what are you drinking today let me know in the comments and it's ready and this is pretty cool watch this all you gotta do is click interact and it's gonna launch the sucker in your browser click go so here we go your very own linux machine your playground hack the box will call this your phone box and i love that so now that we're here inside our linux box we're going to accomplish two things first what is this i understand this may be your first time ever using linux you might be wondering what do i do i don't even know what this is we'll cover that and then two we're gonna start using it right now i'm gonna get you started with your first linux terminal commands and i'll cover what that means so first what the junk is this so this computer you're using right now here in your browser which is crazy this is linux but to be specific and technical this is actually a distribution of linux called parrot os which is an operating system built for hacking now the os and parrot os stands for operating system like windows mac os ios android it's the software that we interact with to make our computer do things so if someone were to ask you hey what operating system are you running right now it would be parrot os and parrot os is using linux and more specifically the linux kernel and i wanted to point that out because linux is technically not an operating system linux is a kernel and we build operating systems on top of it so para os is not the only flavor or distribution of linux there'll be kali linux ubuntu centos debian and they'll all use a version of the linux kernel which is actually part of the os but it's not the os now what does the linux kernel do it has a very important job it interfaces with our hardware cpu ram hard drive etc when we as the hacker want to run our favorite hacking tool let's say nmap or something we tell parrot os click let's run nmap parrot os will say hey linux kernel can we get some hardware resources here can you tell them and linux kernel gets the hardware resources set up it's kind of the middle man between the application the os and the hardware but to simplify things we just call it linux and we say what flavor of linux and we say well parrot os now the bigger question might be why linux i mean we got windows we got mac os what's wrong with those guys well nothing and everything you see what's great about linux i'll explain what's great about linux is that it's open source which means a lot but it basically means that it's open and free to use and redistribute so people can make awesome distributions like parrot os the other benefit of linux is that it's traditionally faster and more secure which is why most websites and servers in the world use linux as their operating system and it's also why hackers use linux most of the hacking tools out there are linux based so that's what linux is and this is why we use it but now how do we use it that's a more interesting question because you might be looking at this screen here your computer desktop and you may be thinking wow i didn't know linux had a pretty gui like this a graphical user interface icons and a dock and menus and stuff like that's cool and you can use linux like this but it wasn't meant to be used like this so slow down the truly wheeled the power of linux you don't use gui you're going to use the linux terminal the command line this guy right here go ahead and click on that i can't tell if that's green or yellow i'm colorblind but go ahead and click on that icon there this is the linux terminal and this is how you are supposed to use linux now if you're coming from the gui only world where all you use is a graphical user interface this might seem a little scary i totally get it but don't worry we're going to walk through this we're going to teach you a few commands here i'm going to slowly wing you off the graphical user interface i'll pull it up side by side actually watch here we go we're gonna teach you your first few commands so follow along with me go ahead and have your linux terminal open and also at the same time open up your home directory right here just double click that sucker double click i'm going to teach you your first few commands by doing something here in the gui and then doing that same thing here in the linux terminal now here's the first thing what i love about the gui is that you always kind of know where you are right because you can see it right now i'm in my user directory my home directory because i can see it right there and there's all my stuff now over here i don't see anything how do i know where i am we're going to solve that our first command type it in with me right now three letters pwd pwd stands for print working directory and it basically does what we see here and here it tells us where we're at hey where am i oh i'm right here let's try it out go ahead and hit enter bam it shows us the full path of where we are right now the home directory and then even further in drilling down our user directory so right now we're actually in the same spot as our gui same location okay cool we know where we are but we still don't see the same stuff in our gui like right now where i'm at i can actually see my my desktop and templates and documents folders and downloads folders i don't see that here how do i see that next command type it with me it's going to be our ls command ls ls stands for list and it's pretty simple what it does it'll simply list the contents of your current working directory it's going to list what we see right here you want to see let's do it go ahead and hit enter and boom it did it everything we see here desktop downloads templates documents postman is also right here see you can do anything in the terminal and it's faster i'll convince you don't worry let's keep going let's say we want to take a peek inside of our desktop folder right here in the gui i know i can just click on that folder double click jump in there and i can see my stuff how do we do that in the terminal our next command here we go the command is c d very simple cd stands for change directory and it's going to do exactly what we just did here watch let's do it right now just after cd i'll hit space and then tell it what directory i want to go to let's go to desktop so i'll type in desktop and go oh did it work i don't know let's let's see let's print our working directory pwd let's see if we actually change to that directory we did there's a current working directory and we did indeed drill down right into the desktop folder and then to see what's on our desktop as we can see in the gui we'll just simply type in ls to list the contents bam there it all is right there now we're gonna learn one more command so hang with me but so far we've done a lot the pwd command to see where we are the ls command to see what's around us what's in our directory and the cd command to change where we are but now how do we go back because like in the gui here it's pretty intuitive we got a back button up here we just go back and suddenly we're back to our directory we started in our home directory how do we do that same thing over here in the terminal it's actually super easy so again we're going to type in cd we're going to change our directory because we actually are changing our directory and then we'll do a space and all we're going to put in is dot dot so cd space dot dot hit enter and let's see what happens boom what happened let's type in pwd and see if it changed our directory totally did so again we were in home user 89786 desktop we entered the cd command with dot dot and that dropped us back to home user 89786 now just for fun i wonder what will happen if we keep going backwards if we type in cd dot dot again i'll type in pwd where i'm at i'm at slash home now let's do cd once more where i'm at now pwd oh now instead of home i'm simply at forward slash and what this is is actually the root of the file system it's the end we reached the end and we'll talk more about that later but just for fun again that's all for fun right here enter the command ls let's list the contents of the root directory huh a lot of interesting files here we'll talk about all this later now real quick quiz for you let's see what you remember right now again if i print my working directory pwd i'm at the root forward slash what command or commands would i enter to get back here where we were to start with now there are two options really you can do it with one command or you can do it with two commands comment below with what you got now here we just scratched the surface we're going deeper into linux we're gonna get you prepped and ready to become a hacker but don't that diminish the fact that you did a lot today in this video we covered what linux is it's both a kernel and an operating system similar to windows and mac but it's faster more powerful and more secure and way more popular it wins that contest hands down especially with hackers we love it and we also covered some linux terminal commands we started to move away from the gui weaning ourselves of the gui and started typing away pwd lscd more to come and again massive shout out to the sponsor of the series hack the box academy hack the box academy which is obviously tied to hack the box it's different in that it's more of a guided i.t security platform and by the way all the commands i mentioned in this video will be covered in depth on hack the box academy and of course don't forget to hack the youtube algorithm today hit that like button subscribe notification bell comment let's hack youtube ethically of course yeah that's all i got i'll catch you guys next time [Music] you
