No lie, he literally condensed a whole 16 week semester of the Linux class I took a year ago at college in 10 minutes. Sir you are a scholar and a gentleman.
There are some lazy Linux teachers out there. They just show their students some commands they could read in a book or watch on RUclips and call that "education". A good teacher should get them programming real stuff in C/C++ and how to shell script properly. I happened to have a really knowledgeable Linux professor that made sure we knew Unix and Linux inside and out by the end of that class, not just some commands.
@theacp127 that maybe fine for someone already familiar with the CLI but for a complete novice, you need at least 4 weeks of reading and trying things out to get familiar. Another 4 weeks of to heavy use to get comfortable and understand what commands you are running. The last 8 weeks would be for understanding the linuxOS and other stuff. This video is good for reviewing commands that you haven't used in a while.

A gentleman and a scholar! Thank you for this. Didn't even have to watch the video. Just goes to show that it's best to learn through reading the documentation, user manuals. It's not only faster but way more informative than watching RUclips videos. It's best if you actually want to learn these skills and remember them. No more 10 hour long "tutorials" that are often wrong and outdated. Even 10 minutes is too much time lost when you could have been learning something more useful. That combined with hands on experience using the command line and you're in business.
@@Average_Josh How do you memorize concepts like its so hard to try and remember all the info. Im trying to get into cyber but I want to learn networking to be good at it.
@@ender_3807 I don't tend to memorize things. I am constantly looking things up. However I work to gain an understanding of how things work. I understand how eigrp, ospf, and bgp function, the specifics can always be referenced. I work to make my brain kinda like packet tracer was. So I can simulate in my head what is going on, even if I can't emulate the full process. That's how my brain has always worked. It also helps me that I enjoy doing that.
You should really research your college before signing up. Also should probably learn that Linux commands isn't universal for all Linux os' if you didn't learn that you probably didn't go to college
Side note: "clear" (Ctrl+K) not only clears the viewport, but the history too. Therefore, if you wanna see what command you run before - it will be impossible. Instead, if you want to clear the viewport but retain the history, use Ctrl+L
Being a newbie to linux, I have been taking a course. Its nice to watch something like this and actually know most of the commands already. Feels motivating.
This might be the greatest RUclips video ever ever made, not that it helps me, but the ease of information that is not as digestible. Great work. This was a master class in tutorials
Saying this again because you deserve the engagement. You basically condensed the better part of 1-2 Linux courses over 10-14 weeks into a 10-minute video.
I love these videos... Not for the initial learning, but as a quick refresher when you're trying to memorize all these or don't use them everyday, it's perfect.
I don't comment often, but here's one for ya. I'm a Sr. Neteng at a small Telco, and I've got two peers that are constantly watching your videos and telling me what they learned from you. I'm pretty impressed with how much they have absorbed from your videos, including this one! Keep up the great content, and maybe you can slide over to the dark side of networking and ditch Cisco for Juniper :)
…but didn't explain a lot of what the options or "funky regexes" did. Yes, it's a nice reminder of which commands there are, but otherwise kinda unhelpful.
I've been procrastinating your channel for years man, mostly because of my own ego as an IT and Cybersecurity specialist but sometimes you need to step down a notch and start from scratch just to see those many many things you overlooked over the years cutting corners to win the rat race. I just decided to left the rat race and start my own business and BOOM now I have time to properly do all this thing again. Thank you, I really enjoy reviewing my entire career in IT with you Chuck! Not because I want to become a better productive employee, nah., because i want to know stuff better this time just for me!
@@gggggggz5 always remember that there is a child behind the keyboard if you see "once i land a job", chill out dude, he's just a kid, we were like him once too.
@@muditkhanna8164 "there is a child behind the keyboard" yeah, the same kids they use slang acronyms and/or abbreviations such as .... tbh, kewl, sh, yolo ... yada yada 🤣😂
Thank you Chuck. It's been 4 months that I'm using Linux bare metal [11 months if virtual machines is counted, 9 months if wsl is counted]. It all started when your video appears in my feed saying "you need to learn virtual machine right now", still remember that feeling, heart beats so fast, hands are getting cold while setting up my very first virtual machine lol. Thank you, learned a lot in this video, and all of ur vids😊❤️
So happy that i knew 99% of it, i've been studying linux for a couple of months and i guess i just haven't been giving myself enough praised for all i learned so far.
I have been in this industry 20 years and I was sure I must know all of these. Never used cmp before. I usually just use an option on diff. Thanks for the new command.
It would be a pleasure to have you as a teacher in a week long course. It wouldn‘t be as boring as in most other courses I attended so far and I believe I would take an understanding and knowledge with me as of a week long training. Thank you for all your efforts!
This is amazing, I'm just starting my adventure with Ubuntu on M1 MacBook Pro using a virtual machine with UTM and I really needed some interesting and useful commands and boom your video appeared on the home page. You explain everything very simply and in a short time. And I absolutely love your videos, keep it up 🙂
For shutdown/restart you can just use "shutdown now" without the -h. Adding -h leaves it up to the system to decide whether to halt or actually shutdown. The -H is for halt which stops processes but doesn't cut the power. I haven't seen anyone halt a system in the field.
Also, depending on your distro shutdown may not actually do anything or exist as a command. systemctl poweroff is cleaner then. (can also be caused by typing su root instead of su root - before shutdown because only the latter properly changes environment variables…)
Great video NetworkChuck. I'm a little farther along in my Linux journey that a beginner so this rapid-fire format is great for me. I can do my research on my own for the commands that are unfamiliar to me. Thanks man! Love this channel.
I haven't use unix/linux for more than a decade. Watching this video made me feel nostalgic. I remember getting MKS Tools just to get started with Unix commands. Later, I got Coherent (Unix for PCs). When Linux became popular, they close.
@NetworkChuck You are amazin. Saved my 10 hours of studying and your videos are actually the best ones out there. You are always my number 1 choice for anything related networking or learning something new. You are Amazing. Keep up with the good work
@@timarmstrong8765 I don't fully agree, there are many companies looking for people who have no experience and are passionate about Linux and getting better! I've enrolled in Computer Science university some years ago, but I paused it because it was not really interesting, I wanted hands-on experience. I started learning Linux and coding by myself in my free time and started in a hosting company as a Junior Support Engineer up to Senior Technical Engineer in 3 years and then I was mentoring members of our team. After that I joined a company as a sysadmin, so everything is possible if you are passionate about what you are doing! :) Good luck mate!
@ 10:00 - using 'kill -9' will send a SIGKILL signal to the process, which can cause issues. If the process has an open port or writing to a file, it can cause issues with your operating system. Best practice is to use a regular 'kill' command to send a "SIGHUP" signal, which tells the process to try to clean up what it was doing before exiting.
Linux desktop is my daily machine for over 10 years now, but i am in linux space since 20 years and even if i know many of these commands is still watch these videos because it makes me remember other commands i don't use that often or i find out something new even after so long, and makes me love linux flexibility even more. And i love this channel.
I knew them all and more(after over 15 years growing my expertise in linux) but I enjoyed watching this video, I just enjoy anything linux,programming and networks!
I wasn't familiar with shred, so I looked it up, and found an interesting warning that users should be aware of: "Take note that shred relies on an important assumption: that the file system overwrites data "in-place." This assumption is the traditional way to do things, but many modern file systems do not do things exactly this way." It goes on to explain that if you use log or journal structured file systems like XFS, Ext3, RAID, etc. the command may not work as expected.
The commands really aren't relatable ? We get that you know big names but it's almost comical when you just throw them around like that without knowing what you're talking about
Awww....This takes me 12 Years back when i started as a fresher in IT. My first job was to manage ETL & Databases in LINUX environment. Seeing this video takes me back to those days, also remembering some wonderful things i did and hope that helps in a upcoming interview!
Absolutely incredible video! I already knew almost all of them but you created a masterpiece of compressed informative walkthrough of important and handy linux commands!
Beware! netstat is NO longer included with some Debian based distros. They say it's depreciated. Maybe they are really trying to depreciate the knowledge of us that have been around for a while. You can install it again with the net-tools package available in some distros.
OMFG. Thank you so much for your amazing video. This is the best video I've ever seen for me personally as an inpatient learner. There are thousands of Linux command videos around on RUclips, but they either talk slowly or are unprepared. I am glad I found your video. Thank you!
i literally have a operating systems test next week and cried when this video popped up on my screen. Thank you so much Network Chuck. someday when I become an actual programmer, i will buy you a coffee :)
I've used Linux for almost a decade as my primary OS on my desktop and laptop, and I never knew about shred. 95% of this stuff I knew already. About 5% of it I use on a regular basis - Vim, sudo apt update and ssh/sftp mostly. Sometimes mv for moving a boatload of files around, or some combination of commands to grab a list of certain files and move/delete them.
When you forget to add sudo to the front of the command that you just executed, just type: "sudo !!" (without the quotes) to run the previous command with sudo. Clear the terminal with Ctrl+l (lowercase L). Much faster than typing clear everytime. Type: ll (lowercase LL) instead of "ls -al". When running ps there's no need to add the dash (-) for the aux. "ps aux" works exactly the same as ps -aux. Save one character. Type: "cd -" to go to the previous directory that you were just in. Extremly useful.
excellent video. I usually don't comment on any of the videos. but he made me do it. He taught me all the Linux commands that I learned in my 4 year engineering course. Hats off to you sir
Personally I'd add "cd -" to go back to the last directory, sed and tr are useful with grep and awk, and "while read do done", super useful when looping through find results (which can use a command that's escaped with "{} \;". I used to pipe stuff into perl -e a lot too but I haven't done much scripting for the last decade or so, I started about 25 years ago in the late 90's on Solaris and sh & ksh before bash.
oh, also must suggest 'dd' command for super useful way of converting data. About a handful of times I've done a full disk replication using an Ubuntu recovery loaded from USB drive, and these handful of times have saved my system state without loss of data, at no cost and enabling me to fix a problem with a backup state. I couldn't find a Windows equivalent that didn't involve substantial cost for drive duplication.
Could you do a video on bash tricks from beginner to advanced? Beginner would be like piping and redirecting stdin, stdout, and stderr. Advanced would be like all the alt hot keys and similarly esoteric tricks.
Damn... that´s probably the best linux basic commands training ever put into the internet. I am completely new to linux and got a bit scared but your video is amazingly informative, only giving information about what command, what to use it for and how it basically works. Thanks a lot
as a linux user i can confirm the best tool to have is google, because most of the commands are rarely used and will be forgotten sooner or later. videos like these are great way to refresh your memory of the things i learned in the past and forgot.
👌Awesome video Chuck to get people started quickly. It all begins with being pointed in the right direction when trying to learn, newbies en pro's alike. These things took me years to learn by googling it together. 👍 Thank you, nice work.
Hey. I have ADHD. It's really bad and its hard to focus. Your video pacing, energy, and humor is really fun and helpful to me and enables me to learn and even be enthusiastic about this. Thanks for this video and the one about SQL basics. an SQL advanced tutorial would be awesome, learning things like how foreign keys work and how to manage more advanced SQL systems.
I usually watch these type of videos to relax as I know all basic commands. I'm not super user in any means, just regular guy working on Linux, but 'cd (space)' will be so useful
Great, these are indeed the most important commands (for debian user :-) Just missing command for groups, pipes (,|) and compile tools (configure, make, install)
fd > find. Yes, you may need to install it. And if you have a really complex query, you may need to fall back on find. But for common searches, it's simpler, more concise, easier to understand, and faster. Personally I just .. don't use find, ever, anymore. It's unnecessary. On another topic, the grep example also seemed like it was really an interactive task and so using fzf instead of grep would be more effective.
This has to be the video that has had the most impact on me! I recently transitioned into DevOps and i need to learn Linux and this is so straightforward! Coupled with ChatGPT i think I'm gonna soar!!!!!

Thnx dude 😊
You are so gooood.May you get successful in life.. my notes are made.❤
A gentleman and a scholar! Thank you for this. Didn't even have to watch the video. Just goes to show that it's best to learn through reading the documentation, user manuals. It's not only faster but way more informative than watching RUclips videos. It's best if you actually want to learn these skills and remember them. No more 10 hour long "tutorials" that are often wrong and outdated. Even 10 minutes is too much time lost when you could have been learning something more useful. That combined with hands on experience using the command line and you're in business.
As a network engineer, I thoroughly enjoy your videos and appreciate the effort and energy you put into them.
hey i have one question, is it possible to contact you? (i am studying to be a network engineer)
@@sulimanmuhammad1350 just put your question here and I should get back to it within a week since I figured out how to find my old comments.
@@Average_Josh How do you memorize concepts like its so hard to try and remember all the info. Im trying to get into cyber but I want to learn networking to be good at it.
@@ender_3807 I don't tend to memorize things. I am constantly looking things up. However I work to gain an understanding of how things work. I understand how eigrp, ospf, and bgp function, the specifics can always be referenced.
I work to make my brain kinda like packet tracer was. So I can simulate in my head what is going on, even if I can't emulate the full process.
That's how my brain has always worked. It also helps me that I enjoy doing that.
He is not truly a network engineer. He only knows crappy token ring
bro just taught me more than almost 7 weeks of college classes. Thank you, wish I had lecturers as passionate and well spoken like you.
You should really research your college before signing up. Also should probably learn that Linux commands isn't universal for all Linux os' if you didn't learn that you probably didn't go to college

Side note: "clear" (Ctrl+K) not only clears the viewport, but the history too. Therefore, if you wanna see what command you run before - it will be impossible. Instead, if you want to clear the viewport but retain the history, use Ctrl+L
Just tried it on fresh Kali, clear doesnt clear the history and ctrl+K does nothing
Is Ubuntu acceptable to use for Linux commands?
Just use: clear -x
It won't clear scroll history

Ctrl + K erases everything after your cursor
Ctrl + U erases the whole line
Ctrl + L erases all bottom lines except the line you are typing
Being a newbie to linux, I have been taking a course. Its nice to watch something like this and actually know most of the commands already. Feels motivating.
7 months of studying later. Its funny to think I felt good knowing just these basic commands lol. Just got my linux+ and getting ready for RHCSA.
@@arandomdude8701good stuff mane
@@arandomdude8701 So these 60 commands aren't enough?
@@arandomdude8701 Which course?
@@tanvir3947Nowhere near enough, they're awesome for beginners but obviously not everything
This might be the greatest RUclips video ever ever made,
not that it helps me, but the ease of information that is not as digestible. Great work.
This was a master class in tutorials
Saying this again because you deserve the engagement. You basically condensed the better part of 1-2 Linux courses over 10-14 weeks into a 10-minute video.
I love these videos... Not for the initial learning, but as a quick refresher when you're trying to memorize all these or don't use them everyday, it's perfect.
I don't comment often, but here's one for ya. I'm a Sr. Neteng at a small Telco, and I've got two peers that are constantly watching your videos and telling me what they learned from you. I'm pretty impressed with how much they have absorbed from your videos, including this one! Keep up the great content, and maybe you can slide over to the dark side of networking and ditch Cisco for Juniper :)
Aruba is the way my friend.
I didn’t even realised how fast 10 minutes went, but the amount of knowledge shared in that short duration was very helpful.
I finished this while video in 2 days 😀
This guy summarized 15 weeks of unix learning in just 10 minutes
…but didn't explain a lot of what the options or "funky regexes" did.
Yes, it's a nice reminder of which commands there are, but otherwise kinda unhelpful.
I've been procrastinating your channel for years man, mostly because of my own ego as an IT and Cybersecurity specialist but sometimes you need to step down a notch and start from scratch just to see those many many things you overlooked over the years cutting corners to win the rat race. I just decided to left the rat race and start my own business and BOOM now I have time to properly do all this thing again. Thank you, I really enjoy reviewing my entire career in IT with you Chuck! Not because I want to become a better productive employee, nah., because i want to know stuff better this time just for me!
@TheDrAkira so how is you business going after the year? I'm just curious random guy from internet :)
I'm studying for Comptia A+, this video covered many basic command needed to use Linux. Thanks
I love this dude... im leaning cloud computing (GCP) once i land a job, im defff supporting this channel in everyway i can... thank you Chuck!!
Graduate from highschool first
@@gggggggz5 always remember that there is a child behind the keyboard if you see "once i land a job", chill out dude, he's just a kid, we were like him once too.
@@muditkhanna8164 "there is a child behind the keyboard" yeah, the same kids they use slang acronyms and/or abbreviations such as .... tbh, kewl, sh, yolo ... yada yada 🤣😂
Here for the same reason rn. Interview I'm 10 minutes lol
Thank you Chuck. It's been 4 months that I'm using Linux bare metal [11 months if virtual machines is counted, 9 months if wsl is counted]. It all started when your video appears in my feed saying "you need to learn virtual machine right now", still remember that feeling, heart beats so fast, hands are getting cold while setting up my very first virtual machine lol. Thank you, learned a lot in this video, and all of ur vids😊❤️
Hands shaking on making a machine that literally can be fucked up without worry ? Are you a child playing with a pc for the first time ?
Man you are awesome i want a teacher like you.
I guess already you have it 😜
I was thinking the same thing.
awesome indeed.
Gigalinux chad
Right here he is.
This video nails it!!! Absolutely excellent: No BS, no blabla, just pure knowledge.
The BEST of all. Thanks Chuck!
So happy that i knew 99% of it, i've been studying linux for a couple of months and i guess i just haven't been giving myself enough praised for all i learned so far.
that 1% was worth it because the video was just 10minutes
I have been in this industry 20 years and I was sure I must know all of these. Never used cmp before. I usually just use an option on diff. Thanks for the new command.
It would be a pleasure to have you as a teacher in a week long course. It wouldn‘t be as boring as in most other courses I attended so far and I believe I would take an understanding and knowledge with me as of a week long training. Thank you for all your efforts!
Make sure you have 15000 coffees ready, he can't do shit without it and a gazillion tantrums! He can barely act professional, can't be a teacher
this is my kind of video, no pre-yapping, no post-yapping just 10mins of actual. Another Sub here mate.
10 minutes of yapping about non universal commands
1:27 > will replace content of existing file. >> will append.
This is amazing, I'm just starting my adventure with Ubuntu on M1 MacBook Pro using a virtual machine with UTM and I really needed some interesting and useful commands and boom your video appeared on the home page. You explain everything very simply and in a short time. And I absolutely love your videos, keep it up 🙂
For shutdown/restart you can just use "shutdown now" without the -h. Adding -h leaves it up to the system to decide whether to halt or actually shutdown. The -H is for halt which stops processes but doesn't cut the power. I haven't seen anyone halt a system in the field.
reboot & shutdown 0
Good info… our LOP has a shutdown -h now…. Later I learned I could just type reboot
Also, depending on your distro shutdown may not actually do anything or exist as a command. systemctl poweroff is cleaner then.
(can also be caused by typing su root instead of su root - before shutdown because only the latter properly changes environment variables…)
Great video NetworkChuck. I'm a little farther along in my Linux journey that a beginner so this rapid-fire format is great for me. I can do my research on my own for the commands that are unfamiliar to me. Thanks man! Love this channel.
I also love:
tldr - for man but with examples in quick
tree - to look how the folder struckture is below the current or specified directory
I haven't use unix/linux for more than a decade. Watching this video made me feel nostalgic.
I remember getting MKS Tools just to get started with Unix commands.
Later, I got Coherent (Unix for PCs). When Linux became popular, they close.
@NetworkChuck You are amazin. Saved my 10 hours of studying and your videos are actually the best ones out there. You are always my number 1 choice for anything related networking or learning something new.
You are Amazing. Keep up with the good work
I've been using Linux for 25yrs and you taught me a couple of new ones. Cheers😁
whos here because they have forgotten 90% of commands again
Not me
Not all of us are drug users sorry bub
I'm a sysadmin and use Linux for years, I'm glad I knew all the commands shown on this video! :D
Keep up the great work Chuck!
I would love to be sys admin as well but with self taught Linux CLI, it take me nowhere. At the end experience matter
@@timarmstrong8765 I don't fully agree, there are many companies looking for people who have no experience and are passionate about Linux and getting better!
I've enrolled in Computer Science university some years ago, but I paused it because it was not really interesting, I wanted hands-on experience. I started learning Linux and coding by myself in my free time and started in a hosting company as a Junior Support Engineer up to Senior Technical Engineer in 3 years and then I was mentoring members of our team. After that I joined a company as a sysadmin, so everything is possible if you are passionate about what you are doing! :)
Good luck mate!
What is the .awesome extension used with echo?
One of the best videos you ever made.🤜
The info, pacing, humor and energy of this tutorial was just amazing, a masterpiece.
@ 10:00 - using 'kill -9' will send a SIGKILL signal to the process, which can cause issues. If the process has an open port or writing to a file, it can cause issues with your operating system.
Best practice is to use a regular 'kill' command to send a "SIGHUP" signal, which tells the process to try to clean up what it was doing before exiting.
I think the default is SIGTERM rather than SIGHUP
If SIGKILL will cause problems to OS then OS will not allow SIGKILL.
SIGKILL will not work if the process is in uninterruptable state.
Linux desktop is my daily machine for over 10 years now, but i am in linux space since 20 years and even if i know many of these commands is still watch these videos because it makes me remember other commands i don't use that often or i find out something new even after so long, and makes me love linux flexibility even more. And i love this channel.
So you watch a 10 minute video to hunt down a command instead of just googling it ? Sure ya do
Hes just wstching it to watch something he enjoys. Not thst deep man lol @@gggggggz5
Wow! 20 years! I am 72 and have been learning for 2 months.
I would also add the command locate. I use it all the time as a quick way to find files etc on the system.
I knew them all and more(after over 15 years growing my expertise in linux) but I enjoyed watching this video, I just enjoy anything linux,programming and networks!
Chuck you're a beast! Just know that. This is too powerful. Thanks man!!!🙌🙌🙏
Man!!!! I learn much better in your videos than at school. You are a genius

@7:57 - traceroute will list every hop /that responds back to the trace/. Not every node will necessarily respond back to traceroute, FYI.
I wasn't familiar with shred, so I looked it up, and found an interesting warning that users should be aware of:
"Take note that shred relies on an important assumption: that the file system overwrites data "in-place." This assumption is the traditional way to do things, but many modern file systems do not do things exactly this way."
It goes on to explain that if you use log or journal structured file systems like XFS, Ext3, RAID, etc. the command may not work as expected.
As an App Support Engineer, using UNIX OS for support. The commands are almost similar from UNIX to Linux. Thanks for sharing this, Sir. 😊
The commands really aren't relatable ? We get that you know big names but it's almost comical when you just throw them around like that without knowing what you're talking about
@@gggggggz5 bro's name is cutie dutch come on how can you be mad at him lol
@@gggggggz5The commands are very similar in naming scheme and function.
Everytime I watch your video, I always have a reason to watch it more.
Thanks so much sir
This is amazing! I wish I found out about your channel when I first started uni.
I would have saved a lot of the hours being lost.
Awww....This takes me 12 Years back when i started as a fresher in IT. My first job was to manage ETL & Databases in LINUX environment. Seeing this video takes me back to those days, also remembering some wonderful things i did and hope that helps in a upcoming interview!
Absolutely incredible video!
I already knew almost all of them but you created a masterpiece of compressed informative walkthrough of important and handy linux commands!
Been in linux every day for like 12 years and still got some gems from that. Well done
Love these kinds of content. Brief, concise, and packed with so much knowledge.
Beware! netstat is NO longer included with some Debian based distros. They say it's depreciated. Maybe they are really trying to depreciate the knowledge of us that have been around for a while. You can install it again with the net-tools package available in some distros.
It has it issues and was replaced, which was partially mentioned
netstat -> ss
ipconfig -> ip
OMFG. Thank you so much for your amazing video. This is the best video I've ever seen for me personally as an inpatient learner. There are thousands of Linux command videos around on RUclips, but they either talk slowly or are unprepared. I am glad I found your video. Thank you!
@shwn2737: You disrespectful asshole!
Be careful you don't get struck down using such blasphemy.
Awesome! And you timestamped all the commands. Kudos man.
This guy timestamps!
Excellent content. Everyone that uses Linux needs to watch this...RIGHT NOW!
Great video, really helpful. please continue making more awesome stuff like this
i literally have a operating systems test next week and cried when this video popped up on my screen. Thank you so much Network Chuck. someday when I become an actual programmer, i will buy you a coffee :)
Excellent video. You present it in an easy-to-learn fashion. Thanks!
I teach a group Afghan refugees (network/security/linux) and this video is great for them. Thanks!
Took a month long Linux intro course. This video teaches everything that took that month but in a much more to the point and easier to understand way.
One of the best videos on internet. Also, every second in this video is useful which is crazy. Thanks Chuck
I've used Linux for almost a decade as my primary OS on my desktop and laptop, and I never knew about shred. 95% of this stuff I knew already. About 5% of it I use on a regular basis - Vim, sudo apt update and ssh/sftp mostly. Sometimes mv for moving a boatload of files around, or some combination of commands to grab a list of certain files and move/delete them.
we need a linux course from you bro your explanations and the way you hand the information are literally the best
Very nice! I am surprised to know that I already know half of the commands that you listed, thanks!! ❤️
When you forget to add sudo to the front of the command that you just executed, just type: "sudo !!" (without the quotes) to run the previous command with sudo.
Clear the terminal with Ctrl+l (lowercase L). Much faster than typing clear everytime.
Type: ll (lowercase LL) instead of "ls -al".
When running ps there's no need to add the dash (-) for the aux. "ps aux" works exactly the same as ps -aux. Save one character.
Type: "cd -" to go to the previous directory that you were just in. Extremly useful.
Nice list, also made me happy, that I know them all :)
As an MS DOS user 20 years ago, this was perfect for me to get back into cmd line.
that feels pretty good to already know most of these commands
excellent video. I usually don't comment on any of the videos. but he made me do it. He taught me all the Linux commands that I learned in my 4 year engineering course. Hats off to you sir
Could be little bit slower, but content is great and useful. Ďakujem.
I found myself pausing to practice. Yeah, it was fast.
@@FlamingCockatiel I changed the 'speed' to 3/4 and "still Paused to practice" :)
Everyone should know this command "sudo !!"
It repeats your last command with sudo infront, for those times when you forget to sudo your commands.
Thank you 😊
I watch these on the way to work and play around once I’m off work these help with my IT courses thank you!
Personally I'd add "cd -" to go back to the last directory, sed and tr are useful with grep and awk, and "while read do done", super useful when looping through find results (which can use a command that's escaped with "{} \;". I used to pipe stuff into perl -e a lot too but I haven't done much scripting for the last decade or so, I started about 25 years ago in the late 90's on Solaris and sh & ksh before bash.
oh, also must suggest 'dd' command for super useful way of converting data. About a handful of times I've done a full disk replication using an Ubuntu recovery loaded from USB drive, and these handful of times have saved my system state without loss of data, at no cost and enabling me to fix a problem with a backup state. I couldn't find a Windows equivalent that didn't involve substantial cost for drive duplication.
Honestly, all your videos are amazing> Thank you> Thank you
Awesome Chuck❤️❤️
Best Linux Commands tutorial video on the RUclips, very effective and straight forward. Thank you so much.
10:45 Just wanted to point out that it's faster to use sudo poweroff than sudo shutdown -h now
u r right
I recently started learning linux, i think this video is for me, it just came the right time . Thanks
Could you do a video on bash tricks from beginner to advanced? Beginner would be like piping and redirecting stdin, stdout, and stderr. Advanced would be like all the alt hot keys and similarly esoteric tricks.
Damn... that´s probably the best linux basic commands training ever put into the internet. I am completely new to linux and got a bit scared but your video is amazingly informative, only giving information about what command, what to use it for and how it basically works. Thanks a lot
Also tell us about plugins you use, like fzf or j and stuff.
It's hard to find out what people are doing that make their experience productive
Tbh i think the whole point is that you create your own productivity
This video is directly going to my favs! even though I have 10+ experience with linux you never stop learning
Thank you sir!
Awesome. Good vid :)
I'm so recommending this video to on board newbies in my development team. Thanks.
My dad was watching me type “finger dad” and was looking at me like 🤨
as a linux user i can confirm the best tool to have is google, because most of the commands are rarely used and will be forgotten sooner or later. videos like these are great way to refresh your memory of the things i learned in the past and forgot.
👌Awesome video Chuck to get people started quickly. It all begins with being pointed in the right direction when trying to learn, newbies en pro's alike. These things took me years to learn by googling it together. 👍 Thank you, nice work.
Hey. I have ADHD. It's really bad and its hard to focus. Your video pacing, energy, and humor is really fun and helpful to me and enables me to learn and even be enthusiastic about this. Thanks for this video and the one about SQL basics. an SQL advanced tutorial would be awesome, learning things like how foreign keys work and how to manage more advanced SQL systems.
Continue python course please!!
Yes!
I usually watch these type of videos to relax as I know all basic commands. I'm not super user in any means, just regular guy working on Linux, but 'cd (space)' will be so useful
I made a video on password cracking and short videos on Linux Commands.kindly watch it and do support ☺️
Can we ALL vote to get chuck his own school?
Great, these are indeed the most important commands (for debian user :-)
Just missing command for groups, pipes (,|) and compile tools (configure, make, install)
Drinking knowledge from the fire hose. Good vid!
as a first year student in informatics, you are my hero and i love you
Seriously this dud has some serious teaching skills great video!
As someone who is studying Linux and it's command this is actually useful and fun to watch
fd > find. Yes, you may need to install it. And if you have a really complex query, you may need to fall back on find. But for common searches, it's simpler, more concise, easier to understand, and faster.
Personally I just .. don't use find, ever, anymore. It's unnecessary.
On another topic, the grep example also seemed like it was really an interactive task and so using fzf instead of grep would be more effective.
This has to be the video that has had the most impact on me! I recently transitioned into DevOps and i need to learn Linux and this is so straightforward! Coupled with ChatGPT i think I'm gonna soar!!!!!
Thanks for putting this together. Been messing around with Linux for awhile and this has helped put all the great commands in one place to reference.
Great video. Keep it up! Been following your channel for the past few years now. Love your vids.
