Linux for Hackers (and everyone) EP 2 -- In this episode, we're going deeper into Linux!! If you want to learn Linux, you HAVE to know where things are! Network settings? Application settings? Linux Commands? (we may delete a few of these, just to see what happens). We will explore the Linux file system to find out where stuff is. And along the way, we're learning 7 new FRESH linux cli commands.
*Disclaimer: The Linux foundations course from HTB Academy is a Tier 0 course, allowing me to show the course content in this video series.

11:40 for anyone like myself who didn't understand why the ls command broke after you deleted it from /bin even though it lives in /usr/bin, it's because /bin is a symbolic link (aka a "shortcut") to /usr/bin. They're literally the same directory.

@gwentplayer9124 Рік тому

oh my first thought was that because he used the sudo command the shell looked for the commands inside /bin instead of /.usr/bin, but ur right, a 'sudo which ls' still returns /usr/bin/ls than /bin/ls

@RyanJohnson Рік тому

What I really like about explaining and renaming the commands in bin is that it puts you in the space of "How would I name it?" and after a little internal debate you more often than not come to terms with the command name being a good name worth continuing with. Command sticks in your memory better because you went on a journey of thinking it through and not having it just being another thing to memorize.

@mygoodspirit8655 2 роки тому

@jeschinstad Рік тому

There is only one way to _truly_ understand Linux and that is completing the LFS. It's a free book that takes you through the entire process of building a Linux system from scratch, compiling every component yourself. It's an incredibly rewarding thing if you're really dedicated to learning Linux and you can build extremely tight systems that way too.

@n0upadi Рік тому

Thank you for making us a video where everything is not just presented but also explained. I hope everyone acknowledges how big of a deal this is especially for learners who have difficulties learning. Of course its mad good for anyone else too! Im studying education in finland. I just have the hardest time finding good videos that doesnt leave big gaps in topics and especially understanding through active learning. Most youtubers understand us viewers as passive learners. Big up to you on this one personally its impossible to learn this stuff for me if there are big gaps in the info or in the understanding. You are one of the very few who goes fast, but doesn't leave gaps in the actual understanding. You explain, give us tasks which are in line with the topic, which make us understand and remember. Most of the tutorials doesnt seem to understand how we need to be guided with the info. The info is just poured on us. Most of the vids have a lot of good data, but we dont know what to do with it, we dont quite understand it and therefore, we dont learn but we might remember, big difference there. all in all. Cheers!

@DeepFriedOreoOffline Рік тому

I think my favorite thing about Linux has to be the picture in picture pop out feature for videos. My main issue with watching UKposts videos while doing something else in a single workspace is that the video always ends up being so small, even in theater mode. You need to take up basically 3/4 of the screen just to get a good size, and then you are also taking up the comment space and everything too. But with the video pop out, you can watch multiple videos at a time, size them accordingly, and still use the terminal or do something else. It's REALLY cool!

@nightfox6738 2 роки тому

If you accidentally try to perform a command that requires super user permissions without sudo (which I do all the time) you can use the !! sequence which will repeat the last command given. This is easier than having to retype 'cat networkchuck' after sudo and a LOT easier than having to retype some of the much longer commands which you will get into later. Instead just type 'sudo !!' and it will just repeat the last command you attempted to run but with sudo on the front. You can also use a single ! followed by some character to go through your history and repeat the last command you attempted starting with that sequence. Say I did some things after attempting to cat networkchuck but I want to repeat that command with sudo. I can type 'sudo !cat' and it will find the last thing I attempted to cat and retry that command with sudo on the front.

@refael8454 3 роки тому

@NetworkChuck First thanks for ur awesome videos Im a big fan!! Question how come when you deleted the ls file from bin file the command ls didn't work if essentially the terminal is using the /usr/bin path? Is it exactly the same file just different path?

@jeschinstad Рік тому

Great catch! /bin is a link to /usr/bin for historical reasons and compliance with standards. So when he deleted /bin/ls, both /bin/ls and /usr/bin/ls became unavailable. So yes, it is exactly that; exactly the same, but with a different path. You can also use bind mounting for this.
