[@aclg6616]

just passed my 1102 and got my certification. Thank you professor!!!! and good luck everyone

[@vitme0090]

Any tips on what to study???

[@joebe123]

i know this is super late but you could check out the professor messer practice exams and crucial exams. the messer exams were the closest to the real exam if yo uask me and they explain all of the wrong and right answers@@vitme0090

[@joebe123]

@@mister4875 I don't know I haven't used them but some people say they are good but contain some information that isn't on the exam objectives. I just did crucial because it was 10 bucks for a lifetime membership. They have PBQs and flash cards. The only issue with Messer is he doesn't make more tests lol. They are really worth the $50 and I feel good supporting someone like him.

[@shadowmario111]

Agreed. I was able to pass 1101 with a 704, but I'm having a harder studying for this one.@@vitme0090

[@elimanator]

Definitely the harder of the lessons for me but after revisiting and writing it all down after hearing it I get it a lot better now. Awesome video

[@s3thsational]

Just took 4 pages of notes on this video, there's definitely a lot to remember about Linux commands.

[@Accuni]

Doing it in a VM Ubuntu alongside the video is pretty fun, and clears up some misconceptions I had while only writing notes/not testing it out myself. I find the Linux terminal is much more of a cohesive and friendly language to learn than Windows CLI. Thanks as always, professor.

[@ReDiiKuLuS]

I agree, and it helps those like myself who have to do the thing to learn... So a VM has made this a breeze :D

[@HughIrons]

Powershell is definitely easier to use than command prompt and has a lot of the same commands as bash.

[@keniqueanderson5409]

Man these videos are great. Brand spanking new to the IT world and your videos have dramatically increased my comprehension. Well done Professor Messer. Thanks for this great content.

[@PUBBYDO]

20:21 I thought that was humorous, the way you said that. Excellent video!

[@curtislee7852]

Hey professor. leaning what i can, looks like i am going to be here a longtime.

[@Bosscona]

Great Summary Professor! The video is concise and very easy to follow

[@christianwinter20]

Great video and content- impressive how many informative content you have packed into this one video :-) also thank you for alle the great and free content you have produced so far :-) Many of your videos have helped me to build a foundational knowledge related to managing operating systems, networking, and security related topics 👍🏻 I would love to see more Linux related content from you >> LPIC-1 or Linux +

[@XyZ-vv1qh]

Easiest material for me. Been using Linux for years, excited to really dive in.

[@CrownedJulz]

Google IT Professional Support Cert really helped with these concepts - good review here and picking back up like a charm. Thanks Messer!

[@ifraaaxwarsame6962]

Thanks prof! Really appreciated for your great content

[@phillipivanov7410]

great video proffesor!!!

[@girlstarawesome]

Thanks for these videos!! You are helping me on my path to the CompTIA certifications

[@akenjigibbons8645]

Impressive thank you for imparting

[@joysticksforjesuschrist]

I like to call this channel Messerpotamia.

[@Lusifer666ful]

While taking a class for linux, my professor would hammer in not to set permitions to 777 or use the command chmod 777

[@phu3393]

To be honest, this video inspired me to study coding lol Have you considered teaching coding classes? 😄 Thank you professor.

[@Ceez350]

Don’t do coding its like learning a new language

[@normalthenormalguy1456]

how is the coding journey going?

[@Kyle-hf2hk]

@@Ceez350 Easier in some ways. With a language if you don't have another person who speaks it to practice with, it's a lot harder. With coding, the best practice is just doing what you learned on a screen.

[@Fizz17]

@@Ceez350 Let the man learn what he wants to learn lol. It's not overwhelmingly complicated

[@PatrickTower-ln7oi]

If he taught Python the way he’s teaching this then he’d be raising an army of programmers

[@raymondmoore5113]

I love seeing all of the Stargate references!

[@nathanwade6726]

this was well done!

[@whiteguydre]

As someone who has never touched a Linux machine I wasn't expecting to learn as much as I did in this video! Would you recommend Ubuntu for Linux beginners?

[@gregperez90]

I have a laptop with Ubuntu, I would recommend it. It's pretty user friendly. The most annoying thing I've encountered is downloading apps. Some must be downloaded via sudo commands, etc. It can get pretty technical.

[@gravity_well5627]

Would you ever have write access without read access? how would that work?

[@hellothisis4u]

I thought the cat command is used to display the contents of files?

[@hassan5708]

Thanks, prof!

[@youngskeamz7270]

It’s tuff to learn Linux language

[@DougFrantz]

Does the mv command then actually move the file into a new file and remove the original file? Meaning it would not longer be on the same part of the physical disk?

[@arstgkneio]

Good question. Looked this up and apparently the file itself isn't physically copied and then deleted. Instead, the filesystem efficiently updates the file's metadata, which includes its location. This change in metadata effectively moves the file without altering its actual data blocks on the drive.

[@lennoxcrockett7511]

If you concatenate 2 files with different permissions what does the new file inherit?

[@Bosscona]

The contents add up when you use for example cat text.txt text2.txt > both.txt this is concatenate the contents of both text file in the new file both.txt

[@HughIrons]

I just tested this and it seems like the new file uses the default permission 644. I used the cat command on files with the permissions of 777 and 644.

[@skayakitty625]

linux my beloved

[@matthewnelson3048]

I tried creating a first.txt file in the directory but Ls -l L but it is not listed

[@professormesser]

You could always use nano to save a file with specific text inside. Nano is the last utility demonstrated in the video.

[@matthewnelson3048]

@@professormesser i figured it out... thanks Prof.... I'm a linux noob :P
