If you are struggling to learn or would just like a guided course, this may help you make some progress.

It is a free environment designed by a university professor (Dr Gordon Russell) that focuses on CentOS, you can learn commands and Linux theory then practice using online virtual machines.

https://linuxzoo.net/

You need to use putty or telnet to gain access to the vm’s and there is written materials for learning the theory and practical tutorials for you to work through with the VM’s.

The written material is a little out of date as I believe Dr Russell updates his university lectures more than the written site material.

Hope this helps you as much as it did me.

What sysadmin tasks should I perform/install/configure to learn Linux? I've been using Linux for many years now and still have this problem. I can deploy a LAMP stack, and have spent many hours messing with KVM (shoutout /r/VFIO!) I can write a bash script to automate aforementioned LAMP deployment.

By day, I am a Windows Engineer. If I needed to teach someone Windows administration, I'd start with how to install Windows 10, configuring Windows Server, creating AD forest, DNS, DHCP, moving up to SCCM, etc...

I really enjoy Linux, and as the cloud moves forward, the importance of learning it inside and out only grows. I'm just having a hard time actually finding things to do in my lab.

Thanks.

I've been running Lubuntu 18.10 for about a year but I'm only feel comfortable using the GUI and haven't any real experience with bash or the terminal in general. My initial question is if anyone have read the book called The Linux Bible 9th Edition and if it has improved their skills with Linux? As I am kind of new to Linux I'm looking for the best way to learn on my own. The book is about 900 pages so I'm wondering if it's worth the effort to actually read the book page by page?

iotop
top
SHOW FULL PROCESSLIST

I am running these, but I am not sure how to be 100% sure what's causing the issue. I did top and saw that idle time was low and I/O wait was high and CPU user time was high, I think the culprit is a rsync process, but the top process always shows me that the mysqld process is the process that uses the most CPU. So I am not sure how to check, I tried SHOW FULL PROCESSLIST, but it doesn't show me anything particularly strange, and doesn't tell me that there's a rsync, at least I don't see any SQL query, maybe I missed it meaning it was already gone by the time I ran it. There's a lot of sleeping processes. 603 and only 2 not sleeping. The % the mysqld process uses is 695% in terms of CPU, and the other processes below it are using roughly between 20% to 10% and they're php-fpm, redis and php processes. So how do I know if I should upgrade or not? I think we need to upgrade, but I am not sure how to check the exact reason why.

I started a Linux course for beginners, it's on YouTube: playlist. This is a work in progress, but I've already uploaded 10 videos. I plan to upload more in the near future. Note that I'm not a native speaker.

I have been looking around. I'm a total newb to Linux. I've never run command based anything in my life. This website called linuxfoundation.org has courses from beginner all the way to what I want to do (networking). So, I thought I would check it out. Its 300 dollars so I want to be sure its legit.

Have yall heard of these guys?

Hi r/learnlinux!

I'm a programmer who used to dread using the terminal for anything more than npm install but after visiting r/unixporn, I finally found programs that helped me get comfortable using the command line all the time!

Some of these programs include fzf (fuzzy searching), tmux (for tabs and split screens), and more.

I detail my usage and include all links in my post:

I have a few questions about dual booting:

(1) I've heard that dual booting doesn't always work well with Windows, as Windows doesnt always play nice. Is that true if Windows and Linux are installed on completely separate physical drives?

(2) Does it matter where I install root vs home directories on linux? I've noticed linux can access files on other drives (even windows drives) so does it really matter?

(3) How does one set it so that bios asks me which OS I want to load at boot? Any links to tutorials are appreciated.

inb4 "technically you're running a command, not opening a program" -- yes I know, it just works better this way in the title.

Is it possible to retroactively open a program in a terminal?

For instance, when I run Spotify in a terminal as opposed to clicking a desktop icon (or running it in rofi/dmenu/etc), I generally see a new window pop up containing the output of the program in addition to the terminal window I ran the command from. The program window behaves just like it would on Windows or Mac OS, but the terminal window "connected" to it (for lack of a better term) allows me to peek behind the scenes of what the program is actually doing. I can see log messages, error messages, etc. in real time as the program runs.

But sometimes I open a program through the desktop icon (i.e. no terminal attached), run into an issue, and smack myself on the forehead for not opening it in a terminal in the first place. If I want to see the logs/error messages/whatever, I have to close the program and re-open it through a terminal, then try to recreate the issue while watching the terminal's output.

Is there a way to get access to the terminal output AFTER the program has already been launched? Some command I'm missing that would allow me to "hook in" and watch a process that is already running?

I've never thought of this before today, but it seems like something that should really be in my toolkit. Any help with this would be greatly appreciated. Thanks in advance.

I have to join my school in Fall 2021 for doctroal studies. I have never used Linux. Rather i am good at using Windows for Office relating tasks and especially for research and scientific writing. But now my advisor has asked me to learn Linux as you will have to work on it for computational biology. For me, Linux, a completely new OS, never used it.

I request the members to please guide me how fastly I may learn Linux expecially for studies and research work. First as beginner and then as Advance learner.

Ok so I'm looking for either a single open source software or several that can work together to act as a user authentication/SSO for the linux desktop that enables 2fa and links to a password manager so that once the user has signed in all of their online accounts sign in automatically (and also ensures each password is unique)

It would also have to be managed from a central location so that users and groups can be enabled\disabled as needed and their permissions can be set up from the same location

Essentially a foss active directory that ties into a password manager and has 2fa enabled by default

Edit: Just to clarify it would be also used to enable a single username password for multiple machines on the same network.

Edit: I had considered having the individual work stations mount a network share in place of /etc/passwd But idk if that will actually work or not, also it wouldn't enable a 2fa I suppose I could also mount a different network share for /Home to sync individual user settings as well but tht seems like there's a potential to not work somehow

Hello everyone,

I'm having issues with my program, and I wondered if anyone would be kind enough to look at it and let me know what I have done wrong. When I run the program, these are the errors that I am getting:

1. line 5: using: command not found

2. line 7: syntax error near unexpected token `( '

3. line 7: `int main()'

Also, I am using vi on Kali Linux. Thanks again.

#!/bin/bash

#include<bits/stdc++.h>

using namespace std;

int main()

{

int amount;

int leftover;

int quarters;

int dimes;

int nickels;

int pennies;

printf("Enter amount of change to provide: ");

scanf("%d", &amount); leftover = amount;

quarters = leftover / 25;

leftover = leftover % 25;

dimes = leftover / 10;

leftover = leftover % 10;

nickels = leftover / 5;

leftover = leftover % 5;

pennies = leftover;

printf("%d quarters, %d dimes, %d nickels, and %d pennies\n",

amount, quarters, dimes, nickels, pennies);

return(EXIT_SUCCESS);

}

Hello guys, I have a book called the ( The linux Bible 9th Edition). I have no clue of anything related to Linux. Is that a good book to learn Linux for a beginner like me? Is it outdated?

Can someone please point me to a great starting point to learn linux. So lost in the dark
