I love this series! It will be useful for many many people for years to come! Keep it up!
I really hope it keeps coming up in searches in the future, but that's definitely the goal. Thanks!
One of the most underrated channels on CZcams. Thanks a lot, Jay!
Hey Jay :)
Thank you for sharing this useful information! I'm in love with your series!
Epic! I wasn't expecting to suddenly see a solution to my 2 problems: changing username and its home directory name. Thank you!
These classes are master level, thanks Jay 🙏
Glad you like them!
Awesome as always Jay!! Thank you.
Super cool videos man! Thank you!
Jay, you are awesome in teaching
it would have been REALLY useful if I had known this 3 hours ago 😕
There's only one solution, we need to start developing time travel. Stat!
What did you do?
Thanks a lot ❤, Useful in many ways for me
I actually was here to watch your review on the pine phone 64 - loved it - but got a little bit stuck with your series. Thank you very much for sharing, amazing!
I'm so glad you like it! This is literally my favorite tutorial series that I produce at the moment. I have a ton more episodes planned through the year.
@@LearnLinuxTV Yes, sir, thank you for that as I am new to Linux and came to the right place. Amazing job you do.
great video just like the animation dropping in the back
From today I will start watching one video of yours everyday
Great series!
Best video on this topic
Your video is awesome.
Hi thank you so much for the effort and this series
Could you provide us with a tool or website where we practice these commands in shell or script
thank you this is very useful
💓
Thank you very much
Still hits today!
VIDEO IDEA:
How do you memorize-keep track of-organize the maze of commands-options-arguments required to effectively use Linux? I am a part-time Linux user and tend to struggle because I cannot remember all the tips and tricks when it is actually time to use them. I end up spending a lot of time searching the web for pretty much everything except the basics. This makes Linux very slow for me so I only use it when I have to.
How do you do it if you are not using Linux 12hrs a day for 10+ years?
FANTASTIC IDEA. I'm not sure when I'll fit it into my schedule, but that is a wonderful idea. Until the video is done, I'll just say this for now. The secret here is that you don't memorize everything. Nobody does. It's totally a myth. Sure, there are going to be a chunk of commands you will memorize eventually (just because you use them a lot) but I have at least 30 text files each about a specific command, and I just read them as needed. And believe it or not, I sometimes consult my own books when I've forgotten something!
Have you tried SRS programs? I personally recommend Anki. What I do is that whenever I find a new command I try out a few examples, then I narrow down a list of "common" expressions and finally I export them into flashcards where I include the command or options and a copy of the output of the console in HTML format. Making the cards is time consuming but in the long run I believe is worth it and you get to review all of the commands every now and then.
Thank you, cool !
Thanks!
hey Jay, thanks for explanation but what's the difference between usermod -l and passwd -l ?
Can I use this playlist to learn the UNIX commands for Mac? Or things are different between Linux and Mac?
Great review ! By the way i am watching this on Fedora 38 :)
Great!
Thanks for the awesome content....Subscribed ✌
I like this video. My liked video file gets too bogged down to keep them all.
thanks, nice
hi! in all your videos are using bash, or a different shell?
Very cool 🕶
To see if a user is locked (or not) : # passwd -S jayl (L : locked, NP : No Passwod, P : usable password) . And # usermod -L jayl is equivalent to # passwd -l jayl ; and # usermod -U jayl is equivalent to # passwd -u jayl.
Could you use newgrp groupname, to refresh group policies, users... ? Instead of logging out/in?
Nice job , could you but the playlist crash course in right order to start from zero 😢
Time to finally figure out what that weird penguin was next to the Windows and Mac logo when I wad little
With this linux crash course can we attempt redhat certification?
Hi!! how are you? when i use the comand su or su - (respond like this; su: Authentication failure
what can i do??
Great
-p flag to change passwords
More brutish than 'passwd' command, which is handy in a pinch.
Kindest regards.
👍!
Please help me, I bought FEENG 10TB External Hard Drive,Portable SSD Drive,Solid State External Hard Drives, now cannot format because show me the error:
Error wiping device: Faled to probe the device '/dev/sdh'(udisks-error-quark, 0)
How can you log in as root if only the user account is created during installation? I’ve tried installing Debian and Ubuntu, and some versions of those distributions only give you the option to enter only the user account password, not the root account password. So, if a root account exists, then you don’t know the root account password!
when you put the music on buddha gonna travel upside down and open a portal to another universe LOL 🤣
Jay, what is your keyboard brand?
I'm currently using the System76 Launch. I'm also a fan of DAS Keyboards too, however their newest model is way too distracting.
Can you move home dir to another fs?
Just out of curiosity, I pinged that server IP... it responded! What?!?!?!
Either I forgot to delete that server, or its IP was already assigned to another instance.
I am trying to change my userid in my VM and keep getting this output
"usermod -l chase kali
usermod: user kali is currently used by process 721"
I have tried logging out and logging into root but I keep getting this message and cant find anything online to help me resolve.
I'm stuck at this error message too. Did you figure out a way to resolve it?
Food for algorithm ;-)
How shortcut to logout ssh?
You allow ssh as root? Not on my machines, and no password logins either, gotta have a key! But I'm guessing you did that just to make it easier for this video or something.
These examples are done on virtual machines that are deleted after the lesson.
@@craigleemehan -- I understand, just thought I'd throw that out there for those who might not realize what a bad idea that would be on an exposed machine.
You're right, it's not good to have root and/or password access enabled. Good call! These I just consider to be disposable virtual machines, most of the time I spin up an instance for recording then delete it when I'm done. But I'm glad you mentioned that!
I love it when my machine narcs on me for fat fingering my password
No end-user should ever have to reach expert status. That is still killing Linux, where new users are told to learn Terminal and Vim, instead of focusing on real-world-daily-desktop functionality and stability.
Can't imagine what people did before 1998 and computers spoon fed people life
@@neilpatrickhairlessTry the 1980's, when the Home Computer Wars started. I was there. I can still hear Commodore's cheap dot-matrix printers grinding away; the smell of new 5 and 1/4 inch floppies; the sight of 8-bit graphics in the morning. We used dial up over copper wire to reach bulletin board services to argue with each other and download adult content. And when networks really became a thing, we networked using coaxial cable and Ethernet cards. That, Sir, was when computers were computers! And every Linux Victory Day (August 25th), I salute the fallen that went ahead of us to pave the way, and the giant's shoulders in multiple fields of science and technology on which computing stands.

Its true that Linux isn't for everyone. Its more for the explorers of alternative and sometimes better ways to achieve things. It isn't perfect but if you do have the time to learn it using your pc becomes a lot more interesting. Not everyone needs to have access to the power Linux offers, and for those people they should stick to windows or Mac. There is nothing wrong with any OS. All of them serve a purpose.
No regular user is going to be using linux. Step aside and let the enthusiasts do their thing
This lessone in crash course are in random order or have learning sense?
Does anyone knows some "crash recovery" tutorial? If we update a Linux distro and something broke, what to do? Is there some crash recovery to trouble shoot tutorial that works in any Linux distro?
Thanks!
No problem!
