Any tips on what to study???

@joebe123 6 ай бұрын

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

@@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.

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

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

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

@Accuni Жыл бұрын

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 Жыл бұрын

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

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

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 +

@@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.

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 Жыл бұрын

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.

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

@BrandonVout 24 күн бұрын

That's just a helpful side effect, like how Viagra started out as a heart medication. In all serious, it just reads and prints the files you give it in the order you give them. The user can just choose to output it to a file, which works with any command output.

@jjvexist 26 күн бұрын

in regards to the apt-get command: How does linux obtain the files necessary to install wire shark? Does it pull it straight from the web after inputting the command, or are the files pre placed within the OS and the command is unpacking them?

@dcirino24 26 күн бұрын

They are pulled from servers that are defined as sources in the package manager, your distro will have some defaults but in some cases you may have to add a new source to install something. These are stored at /etc/apt/sources.list.d in Ubuntu

@DougFrantz Жыл бұрын

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 6 ай бұрын

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.

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

@Bosscona Жыл бұрын

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 Жыл бұрын

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.

@gravity_well5627 10 ай бұрын

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

@BrandonVout 24 күн бұрын

Yes, it's not useful for your typical files but there are a few special cases where it can be. For example, log files where you want users' systems to append their logs onto them without letting users read each others' logs. Outside of files, some commands and external devices are write-only. There's no reason to give anyone read-access to those.
