I read the title and quit my job, okay let's start watching
5 seconds in... >_>
Too soon
Me too! Class action lol
My boss : are you sure about that?
😂
Small insignificant correction: The reason that modulo 10 is 0 through 9 is because those are all the possible remainders when dividing by 10, not because computers start counting at zero.
to make your answer clear, here is a example: dividing 93 by 20: 20 + 20 + 20 + 33. the reminder can't be 33 because you have a 20 in 33, so it would be 4 of 20 and a 13. that's why you put % 20 to a number between 0 - 30k, to get something between 0 - 20. Also a quick math to getting random number in an interval: randMinMax = random() % ( Max- Min ) + Min
if min = 20, max = 33, for first expression : you get random % (33-20), so random nb from 0 to 13. and then you add 20 to it, so you are in the range over 20, and under 33.
@@D.a.n_D ironically that made the answer less clear to me lol
@@D.a.n_D "To make your answer clear" 😂😂😂😂😂😂
@@philipehusani imo he did a very good complement
Actually, this is a significant correction.
We all make mistakes, but we need to have the true concepts down for the new soon to be programers/engineers.
if you want to apply changes in .bashrc file you can just run a command: source .bashrc
No need to logout
True but I think he wanted to emphasize/help beginners remember that .bashrc gets executed at login.
Or . .bashrc
Whenever you upload something, I come to watch that. Not because I don't know these but because of your awesome presentation skill and teaching method. I have learnt a lot from you. Take love❤️
What exactly am I watching ?
Same
You enjoy watching clickbait nonsense?
@@Aerylithe exactly. All his videos are becoming clickbait.
@@PrinceAndrewFucksKids Yeah I do, and it's one of the best channels i found. Helped me to learn a lot of things
I love these! You're an amazing teacher :)
I use bash everyday at work and I can't wait to see if you show something I am unfamiliar with.
I am sending these to all my friends that have some curiosity about learning how to script.
okay you are the best teacher, I really like that you are saying those shortcuts out loud and every time you use them so everyone will remember them after some time! this series are great, I am looking forward to learn more from you :)
#!/bin/bash
echo "What is your name?"
read name
echo "How old are you?"
read age
echo "Hello $name, you are $age years old."

echo "Calculating..."
getrich=$(( RANDOM % 15 + age ))
echo "$name, you will become a millionaire when you are $getrich years old."
Chuck love your content, learning new things everytime I watch your tutorials and the other non-tutorial content you got on your channel been watching you for a while now and loving the content and also I like the way you explain stuff and like the energy you present it to us with is just great, just epic
Hey man I enjoy watching your tutorials and videos, keep up the great work !
Thank you!
Hi Chuck, Just want to let you know you are an amazing teacher. Your style of teaching is entertaining, and your videos are fun and informative. Please keep doing more and more tutorials. Thank you. May the force be with you.
It's all clickbait for money.
There's an entire reddit thread about him doing this crap.
Typical RUclipsr desperate for donations and money.
If he was sooooo good at hacking. Why doesn't he have a job? Doing RUclips for a job with clickbait isn't a job.
@@PrinceAndrewFucksKids ruclips.net/video/wiVhqqfzgIA/видео.html
@@PrinceAndrewFucksKids I agree at some point with you, his thumbnails are extreme. But if you dont make clickbait nowadays, you will not make it into the algorythm. Without clickbait, many youtubers would need maybe 10 years for 1Mil. Clickbait accelerates it significant. Whatever, atleast he is showing something interesting, or relevant, or "good to know thing". Better than content thieves and commentary channels, sitting and talking about some exposed person.
@@bendze I won't disagree with you there mate. In that sense I support your reasoning. Have a great day. It Always helpful and positive to see a different perspective you'd may not have seen otherwise.
@@PrinceAndrewFucksKids you too, yeah luckily there are still some people left with some reasonable opinions amongst the comments. I dont blame the fanbase at all and the positive feedback, but lots of fans say what the youtuber wants to hear, like being too emotional and only saying "omg I needed your video today" and at female ones "i love you so much"
Self confidence is only based on fans who already love the creator and constructive criticism is a rare card here.
Thanks for the explanation. It was such a nice explanation and so interactive. If you could teach about networking or cloud concepts a lot more, this channel is going to grow exponentially.. Thanks chuck
Hi Chuck, I was having problems in my computer(ubuntu) sounds, and every time it occurs I had to write some commands to fix it , now after I watched these videos I have wrote an script (my first script) to make the process easy, thanks a lot for these videos
You break down scripting better than my CC instructor. I love your channel, and all the fun labs.
To add after editing .bashrc, so that there's no need to logout/reboot the system all you need to do is type in the command "SOURCE ~/.bashrc" and whatever you added into the .bashrc file will immediately take effect.
Nice video for bash newbies :) Good strategies shared ! Keep it up man 😉
Newbies who get bewbies 🤡
Your channel is so special because of the way you teach. I love it
I love the speed/pace you have in you videos
This is brilliantly done, thank you for keeping it simple. Natural teacher right here.
Loving the BASH series my friend!! Fun to learn on my Linux machine, practical to apply to my Mac environment at work!
who doesn't love Virtual machines speed talking in Linux
Thank you for making these series, it really helped me alot ❤️
Me too, he is great! I am studying by myself and he is very helpful!
Do you know how to install a virtual boxe on a pen-drive? I need some help😅
The rare case when advertizing makes me continue to watch instead of skipping a whole video.
I love your way of teaching. You are my favorite tech channel on youtube. The energy and way you present are so much fun, even for stuff I already know.

Hey wassup
hi wow very good
early gang?
Lets goooo click bait
loved it
I love this series , see you in next episode CHUCK ! ! ! 💛💛
Keep up the good work, your making the begining of programing fun for people and sharing the know how in a fun way. FYI I'm a software engineer - c#, javascript, gosu, sql, ssis, anything the job needs me to know
For every user who is on a proper linux install: For setting global, permanent variables edit /etc/environment and add your variable there (how you would do it in a script), log out and in again and you/everybody else can use it.
thanks, I was just about to ask this
Hi Chuck! your programs are really informative and helpful in learning a lot. A small suggestion... In this episode you said "go and watch episode 1 & 2", so it would be really helpful if you could keep the links for reference of such connected episodes in the description.
Hey man you are the best teacher.
Please make more and more videos for bash scripting please please I really need this info to learn more to make my future so please make more videos of bash scripting I have watched all of your bash scripting series
Thank you for this video ;;~;;
I was having a hard time wrapping my head around certain things in my intro to UNIX/Linux class, this definitely helped!
Bro, you are an incrível teacher. Oh my goodness. Even tough I know most of it I still learned loads and you made it super fun, super powerful and so much more.
Amazing stuff man.
Great job!!!!!
I think you mean *incredible? I consider myself a master of the English language but am confused by what you wrote.
@@snowfreeze you are spot on. Well done.
I speak six languages and my keyboard was on Portuguese while I was typing and I hadn’t realised the auto correct had changed incredible to incrível.
I like your style of teaching, really fun and educative at the same time
I think your videos are the best Linux and Python tutorials on the interwebs.. lol
Practical, to the point and super fun.. thanks Chuck :)
Thank You Chuck! This was the Linux intro I needed.
I noticed you updated .bashrc for restarts and export for child processes, but I wasn't sure if the variable applied to all users, or how to set a variable for all users?
Great video! Big fan of your presentation.
The .bashrc in your homedirectory only applies to the user to who it belongs. If you're on a proper linux install (bare metal or vm) there's also a .bashrc in the /root directory (sudo nano /root/.bashrc) but the better way to set permanent global variables is to put it into the '/etc/environment'-file (just how you would do it in a normal script). Log out and back in again and you're ready to use it.
Bash skills almost maxed out. Where's my millions at?????? :D
"not really"
Wait until he brings the video about bash-loops out!
until [[ $USER == $rich ]]; do
echo "print me money!!"
done
😙
I like your content
I hate click bait titles
Yeah I unsubscribed after this one. His stuff is really only for beginners anyways
So you clicked because you actually thought you could get rich with a bash script and now you're dissapointed?
Why are people getting angry like kids lmfao like how do you expect to get rich with a bash script, fr idk what is up with people just getting mad at these types of videos lol they are just for education if u don't like it lol just click off or smth
😂😂😂
Dude. It's a sarcastic title. Do you actually believe there is a script , that can make you a billionaire??? . Then this title is for you 🤣🤣😜
Thanks so much for this. I may end up using these tutorials for my high school students in computer science.
You mentioned using Linode for your business. Do you have a video talking more about what that looks like for you?
A round of applause for the best RUclips teacher
Again, this tutorial is awesome. Bash forever!
thank you!
thank you so much for everything i love watching your videos i learned a lot from you more than you think, keep doing what you are doing, you really changed my life and mindset. Big respect to you
I swear the coffee sip edits are just perfect
bro pls continue this series without any break. i love you so much. you just change my life :)
14:50 it's because there are 10 equivalence classes of Z/10Z, so there are 10 elements that are mapped from Z to Z/10Z
Cool!!..
Simple and clear, i like it, keep up the good work man.. love it!
I love this series!!
Can't wait for the next video
Just an FYI for people who don't know. You don't have to log out and log back in to pick up updates to the .bashrc file. Just run the command: source .bashrc NOTE: The command I put assumes that you're in the same dir as your .bashrc file if you're not then just point the source to the location of the file example: source ~/location/of/file/.bashrc
No
@@hardscope7744 That's cool. Waste your time logging in and out to pick up changes lol
@@joelmelendez2927 sorry brother I meant for guy underneath your comment the troll not you your answer is valid thanks for info my friend
$SHELL is the default shell and so not "always equal the current shell we are currently using"
I have learnt a ton in this video. Thanks a lot Chuck, you're the best
Sometimes when I get into a funk and I'm all cranky and grumpy....I just watch your channel and remember to change my attitude.....🤘💯😎 Love the channel guy.... 😆
The "Bob Ross" of networking.
Always love your videos man.
Love your videos! thanks to studying everything you put out along with my own education, I recently landed my first job in IT as a network engineer! Only work experience I have prior to this is military/law enforcement related. So thanks for helping me jump industries and keep doin what your doin!
Dude just taught us how to script a digital version of the Swami from the movie Big Starring Tom Hanks. Thanks Chuck I do see how I could at least make something with a random generator. It doesn't even need to be for those paramotors you set. The options are limitless. I love you dude. Thanks a million.
you are great, I just found you my accident. I am an experienced Software Engineer, and very experienced with BASH scripting, you are very entertaining, I never thought writing a "hello world" program was so exciting. I do have a question, when will you get into regular expressions, within the context of "sed", "awk", and etc?
I think its hilarious that Linode gives you 100 dollars in credit for 60 days even though if you used it 24 hours a day every day for 60 days, the total would come out to $14.40, so unless you were running about 6 different operating systems at once with Linode 24 hours a day for 2 months, you wouldn't need more than like $15.
You can just set up a more powerful and therefore more expensive system in that time, this way you can take advantage of the 100 Dollars.
I love these videos. You have taught me so much 🔥💚
Honestly bro, you might be the best teacher on the internet.
Signing up for the academy today. AND I will see you on live when you interview me.
When I did the millionaire calculation, I got an error message saying that it expected a "primary" for the arithmetic expression. Any idea what that means? Awesome video!
My favorite training script is a script maker asking for a filename, adding .sh , creating and opening it in nano and adding x to the permissions
Title suggestion:
automating automation
Also let it move it to ~/bin or ~/.local/bin or /usr/local/bin (system wide) so you don't need to do the ./ to run it! And technically you don't need the .sh-ending as well when it's there.
thanks for the idea, I did it because of you
@@audiolatroushearetic1822 you don't need the file extension no matter where you put the script.
Chuck reminds me of a big kid showing off his favorite toys to other kids that also love those types of toys.
Guys, I realised a bash script for my MacBook that switch power on or off (on a smart plug) based on battery level. I can now let the cable always in and not stress my batteries!
Bash scripting is very nice!
Impressive.

This was great! Looking forward to the next one
I do pentesting and red teaming... I largely live in Bash scripting because at higher levels of expertise in hacking, you simply cannot get things done with tools someone else built (and oftentimes, the tools you want do not exist). The people that claim you can be an expert hacker, pen tester, or red teamer without knowing how to write scripts or code in Python or some other language are misleading in their "wisdom" because they do not know what they do not know.
"They do not know what they do not know."
The sky is blue because, the sky is blue...
@@mrwhosmynameagain False equivalence and you misinterpreted what I said. What I said, which you quoted, is a common saying. Look up "Dunning-Kruger Effect" and its relation to ignorance of "unknown unknowns."
title is a lil *too* clickbaity
We will become rich. Rich in knowledge!! Right Chuck? Great video! 💪💪
You are great! You are very good at what you do and your teaching method it is amazing!
I clicked on this so fast. Thanks for all you do! Your content is top notch
What's with the clickbait?
the tape trick is super cool, if you also add the old TV signal interruped screen at the outro's end ..oh man it's already there!
I've been using bash for a long time and there is no need for me to watch these. But these are very entertaining. Hours-long videos from you would be very welcome for the advanced topics.
The crypto market has been favourable in the past weeks, I keep missing out on this opportunity, I'm most certainly very impatient how can I ever make a profit in the crypto market.
Despite the financial crisis, this is still a good time to invest in Crypto as the market is favourable💰💱
I invested in both stock and Crypto but I'm doing much better on Crypto with the favourable market price.
Access to good information is what the investors need to progress financially and in life. Here is a good one and I'm grateful.
Such a wonderful personality, you’re totally a genius with your work and you have the best options.thank you for your help expert Derek Madison.
I’ve been trading crypto with expert Derek Madison for over a year now and I've made about a whooping profit of $86,000 in crypto its not much but I'm ok with the progress since i now make a whole lot from the comfort of my bed.
Eu oro todos os dias para que uma música nossa estoura 🙏🏼🎼 eu tenho fé, e sei que um dia vai chegar o dia 😭🙏🏼🍀..
Shut up bot lol
Thank you for your Chanel. You keep it fun bro!
Tell Me How When You Said “I’m Gonna Make A Little Loading Screen” My Connection Paused I Thought You Were Building Up Suspense But RUclips Was Loading 😂😂👏
So funny, very nice mr.Chuck, your intro is pretty convincing!
I hope it's not a clickbait, I quit my job yelling atop of my lungs before playing this video! Let's go!
Good video & Thanks ! As a side note, I accidentally left the $ out of the RANDOM in the getrich expression and it still worked!?
This whole video is awesome! I am learning so much! Love it.
Man... Chuck... Seeing you and your energy made me notice how I am when I'm lazered on coffee XP
Love it!
beside your awesome videos, i really really like your video editor's job nicely done nick
Every time he says "Aren't you excited??", my heart races and I'm like bro of course i am!!!
MAN !!! what a video, I am amazed when I think that you made this no one infront of you. well spent 19 minutes
What a great teaching style! Looks like I'm gonna deep-dive in ChuckWorld.
Interesting video . Would you ever consider doing a video doing BGP ( ip sharing ) and how they are beneficial? Thanks. Love your videos.
You break every myth from technology. Keep it up Sir.
Cool Chuck, u give the beginners some exciting perspective and teach bash to them in a fun way. And although these things u show isnt nearly begining to scratch the surface of what bash scripting is u plant a seed they can continue growing on their own (luckily at this point they still r clueless of how deep the rabbit hole is..). Congrats, this is a noble cause.
Now regarding bash, did u know u can also perform math on bash using ---> let ?
The syntax would be something like this:
let i=$MYVAR+1
Thanks Chuck for your time!
Shebang!! Did that scare u!? Lol 😂 love ❤️ u man, thanks so much for the great content and the fun that comes with watching it!!!
Lol nice presentation, love the way you present variables n simple math in bash, awesome
Command 1: Calm down
Command successfully run.
Command 2: Take a sip of coffee.
Heats right back up
Thanks a Lot! @Chuck, I just solved a problem of "command not found" with export
The sound of that mechanical keyboard is on point!
Olá! Big fan from Portugal. I Starter Linux watching your amazing tutorials. Have you ever done one about crontab?
every freaking time I watch one of your videos I learn something. I learned about the $(()) and read $variable expression this time! I always learn some new trick that I no longer have to google!
I’m highly interested in sooo many different things; all of which, I also, HIGHLY *SUCK* AT. What I’m getting at here.. is that.. if I felt I had any chance in hell at becoming great at computers, it would be your videos that probably could get me there; and where I’d start my learning.. You make things very understandable.. and, dare I say it, *fun* to learn! Keep up the good work, Chuck. Thanks.
You make linux tech understandable! Thanks Chuck!
Dear chuck i have a question here 8:45 , you had set up the variable twitter in your console but do we have to export twitter again when we close the console and open it up again or does the script has some sort of memory? Thank you
10:40 ahh got it thanks!
LOL! Chuck, you are amazingly fun. Thank you for what you do.
You are awesome. Thank you very much for making such interesting learning videos.
Am 31 and starting my journey into cyber security, I have alot to learn am learning python, SQL , Linux and bash ugh
But am lucky enough to find such amazing content..
It was outstanding chuck!
We need more videos tho :)
