Linux Terminal Basics 3 | Paths, Storage and System Monitoring 

I studied the book "The Linux® Command Line" by William E. Shotts, Jr. And now I follow along your videos on my Linux Mint 19.03 PC to cement this knowledge with practice. I thank you for having such kind heart and share your knowledge with us. May God bless you.

Joe. You have always helped with these linux videos. I couldn't fully get into linux and understand the basics stuff about linux if it wasn't for your videos back in my windows 7/XP days. You have inspired me to do like you tried helping other understand linux. You mad geeky stuff down the earth for the simple user. Thanks my path/future in linux you have truly played a part in.

I have many fathers, you are one of them. Much Love

Joe, thanks for this series of videos on BASH. Very informative, you are a good teacher

Just learning and loving it! Keep them coming brother.

Completely agree to not cut the misstakes, we all do them and we learn from them. When you mounted the wrong device, it will learn everyone to do ls before anything else just to check. You probably saved someone from a Ooops situation. One common misstake is ls somedir , see some junk and then rm * :-) There is no undelete, but there is timeshift and backup/restore and they are the rescue.

Thank you so much for sharing your experience and time ! I'm quite new to Linux (few weeks), and my first experience was installing MX Linux 19.2 Beta on an old Dell Inspiron 1720 Laptop. Had a lot of fun, learned a lot, then I came across your site a few days ago, and based on a few of your other Vids, I installed Linux Mint on another laptop yesterday! Like em both for now, Mint for obvious reasons as you so clearly show in the video, and I'll just keep MX around to play with, and this series is just in time for me! Thanks again!

Joe, thank you so much for your time and effort creating this great series and all of your other content. You are a great teacher and not editing out your mistakes teaches me so much more. I'm so glad I found your Channel. Keep up the great work!

I already have a lot of experience with Linux, as it has been my daily driver for a few years now, but still it was really nice watching this video summarize everything and just being like "Oh yeah, that thing was there" Very nice video!

Great video Joe! Clear and concise!

Excellent Joe, really like this series, I'm a newbie to Linux; running Linux Mint 19.2 Tina. Can't wait for the next part. Thank-you.

Mr. Collins, awesome series so far ..i combine the series on bash shell script basics with this series and i have found my self at the point where i am starting to guess whats coming next before you say it..that tells me im no longer totally befuddled ..im finally seeing it make sense and how it flows.. its even sticking in this 59 yr old brain..lol..look forward to the rest of the series with antisapation..and thanks for the chuckles in this one.. :)

for the mount command you can use mount | column -t to format it in the tabular format.

Another great video. Regarding swap. Completely agree with Joe. You can change the "Swapiness" to 10. This will tell the kernel to prioritize memory over the swap.

Thank you Sir for your efforts.

Thankyou thankyou thankyou... that tutorial helps SOOOO much!!!

Great video Joe. Learnt heaps and many thanks! I find the mistakes are a great learning tool as after a while we can spot the mistakes as they occur. FWIW, I was able to run blkid without sudo - my system is running Linux Mint 19.2 I did not copy what you were doing with the USB stick as I could see the power of the dd command in wiping the drive - I just watched what you did. Great way to learn to respect the power of your OS. :)

About the swap thing, another point to mention ... if you ever plan to hibernate your system, you need swap of at least the same size as your RAM. Else it cannot save what's in memory and then recall it once you turn the machine back on again. So yeah, swap has some uses besides just running out of memory.

Glad you're back pal!. I'm using parrot os for a while but unfortunately my btrfs file system has been corrupted. I've tried in several ways to fix it off but nothing is working. I'm just getting csum failed in my kernel ring buffer. I came to know about that something is going on in my system internally by taking a look at my system monitoring gui utility. Dmesg helps me to view the errors msg. And I tried the tools like scrub etc... Is there any possibility to fix it?.I googled and raised this queries in many forums but I didn't find the perfect solution. I'm just stumbling with it.

Hi, first of all , i just wanna say thank you for all these videos that you're making, they are extremely helpful! Could you please tell me what is the theme that you're using for your terminal? It looks great! Thanks and keep on rockin'!

Good stuff. Thank you!

All very helpful Thank You :-) Just one question, are you near a train track or am i hearing things again?

Good video... Could you make a video that teaches more how to use chown and mounting drives... I got a little lost in the video when you did chown joe: joe... how do I know who owns which file? ls -al ?

Thank you, Sir.

Thank you

JOE, Now why do you have duplicate path elements? One path element missing is ‘.’, and that usually (should be) the last element in PATH. If that element is in PATH, it will execute scripts in the current directory. Because it is the last element, any “spoofed” command that pretends to be a system command won’t get executed because the system directories will be found first. Also, ~/bin should NOT be found before any system path. It should be next to last in PATH. Again, for security reasons.

I think if you have a Threadripper 3990wx with 1TiB of RAM you don't need a swap file.

added to my list... PS:the "bs" was welcome....

Warning to those who like to blindly follow along with the commands on their machine. DONT. I would have wiped out my home drive if I had done that because my sdb is my home drive. Don't set cruise on your RV and get up and go to the bathroom. It wont work. 53:25 HEADPHONE ALERT!!
