Graphics user interface as how?

Borwe:


You mean Java the Oracle version?
Yeah I know, and if you want to use it, just learn java.

orobogenius:
This is good sir. Quick question: what does the -n option in echo and -d option in the if condition do?

Ok ladies and gentlemen, I apologise for having not updated this thread in a long time, I have gone ahead and created a script for you guys to assess. Again, its a very simple script written in the BASH programming language. The purpose of the script is to iterate through an entire process in which it searches an entire Directory (utilising a For Loop), and then upon reading the directory, it returns whether the elements within the directory are either a File or another directory within a directory.

In Image 1, I created a few files with names of our beautiful Nigerian Ethnicities (sorry if you do not see your own, I was in a hurry to update this thread), and 2 directories in which I place Fulani Music and Hausa Music. Please have a look.

In Image 2, you can find the source code of this simple script.

Okay. Cool!!


I have a question. I have been hearing alot about LINUX and trust me, I wish to know. The noise is too much.


To the question :-

DO WE HAVE COMPUTERS PRE-INSTALLED WITH LINUX? I mean, Hp makes WINDOWS INSTALLED PC. Apple, MAC OS X . . . Do we have for Linux?




Second, what are the minimum requirements if I were to say that :- I WANT TO REMOVE/FORMAT MY HARD DISK AND INSTALL LINUX FRESH!!




Can I erase Windows on an Hp or Windows laptop generally, and put Linux there? Does that mean that the computer's keypads (like start button) will be obsolete on Linux? Or Linux also has something for that?



Please, i have NEVER USED ANOTHER OS apart from Almighty Punny Windows. I even taught myself to use a PC. Didn't attend a computer training like my friends. HAVEN'T EVEN PERSONALLY USE MAC OS X before.

MOM1:
How do you test Oracle network connectivity by using command on the Virtual Machine?

Fulaman198:


Hey brother, you have some very excellent questions. Before I address them, I wanted to take the time to say that your story about teaching yourself general computing was very heart-warming and i urge you to continue on that path. Now, let me address your questions.

Are there computers that come pre-installed/pre-loaded with Linux? Yes, there are a few, one may be able to find Ubuntu Linux on Dell, HP, Lenovo and Asus computers. However, they are hard to find.

Minimum requirements for installing Ubuntu Linux are even less demanding than Windows OS, they are as follows: Ubuntu Desktop Edition
700 MHz processor (about Intel Celeron or better)
512 MiB RAM (system memory)
5 GB of hard-drive space (or USB stick, memory card or external drive but see LiveCD for an alternative approach)
VGA capable of 1024x768 screen resolution.
Either a CD/DVD drive or a USB port for the installer media.

I do urge you to install Ubuntu as using it is quite simple. The GUI is quite easy to familiarise yourself with.

You definitely can overwrite Windows OS all together with a fresh Ubuntu Linux installation. It may take about half an hour or so for the entire installation process. Feel free to ask as many questions as you like.

Dekatron:


This is really good news!!




But, I wish to know :- WHAT EXACTLY CAN LINUX DO THAT WINDOWS CAN NEVER TRY?



If I wanted to port to Windows back, how do I do that??



Can I create a partition on my PC (Hp, SATA HDD) and then install Ubuntu on the second partition?


THANKS SIR.

Fulaman198:


I am a bit confused by your question my friend. Testing network connectivity can be done in numerous ways.

For example, if you want to test LAN connectivity (meaning Inter-Network connectivity) what you could simply do is ping devices on your network. Some devices would include your network printer, another computer, your non-VM local IP address, etc.

To test and see if you have connectivity outside of the network, you can try pinging google.com. Let me know if this answers your question. Thanks!

MOM1:



When running the oracle virtual machine. If you need to test connectivity with the host. N.B. the host did not provide the ip address. How can one use the command TSNping

Borwe:


Which OS is that your using?

Fulaman198:


That is Linux, but CentOS Linux.

Borwe:

Looks like white version of Debian

Fulaman198:
Is there anything in specific that you guys would like me to show you or demonstrate?

gimakon:


Have you ever used mandriva linux?

Fulaman198:


Nope never, only Kali Linux/BackTrack, RedHat/CentOS, and Ubuntu. Is there anything significant or special about it?

gimakon:


Um... not really. that's what I used before switching to kali. But it's flexible from what I see.

I have so many bash scripts written by me. This script works at least 85% as the builtin id command . enjoy

Dual-booting Ubuntu Linux is quite possible and very easy to do. There should be numerous videos on how to do it on YouTube. Porting back to Windows is very easily done as long as you hold onto your Windows Product Key. Make sure you keep that for safeguarding.

Ubuntu Linux has some things that Windows lacks (mainly at the command line). But you have to be very technical to use these tools. Linux has built-in SSH capability at the command line. With Windows, you need a 3rd party tool like PuTTY in order to utilise this command line function.

There are many ways to install Ubuntu, you don't even have to create partition, you can also create a Virtual machine and see if you enjoy it (though depending on your current computer specifications, Ubuntu may not run quickly as a VM). VMPlayer and Oracle VirtualBox are free VMWare software that enables one to install a virtual machine image of their choice.

Practically, I view Linux as a more secure and stable OS than Windows. It really is a great OS for developers and people who are just every day users.

Dekatron:



sorry for the no-response. I have been lazy to reply mentions- most mentions.



Sir, does that mean that I can download a VM of Linux. By that, you mean I CAN RUN LINUX AS THOUGH AS ITS THE INSTALLED PRIMARY OS?




If I were to download the VM, do we have ubuntu Linux VM? Where can I download? HOW MUCH IS THE DATA SIZE? 3GB? 10GB?




Do you have the idea of the minimum spec needed for the Linux Ubuntu VM (If the particular type exists?


Thanks in advance. I'd resuming to sch probably this week (EEE, 200L). I'd have access to WiFi (not free though), so I wanna know all I should abt the VM. . . . And possibly, I'd buy a SPECIAL HDD for Linux. Will you, as an experienced computer person advice that? Using different HDD for each O.S?



Thanks.

Fulaman198:


My brother, thank you for listening!

You would want to install Oracle Virtual Box prior to downloading the 1.2ish gigabyte Ubuntu Linux.

To get Virtual Box, go here: https://www.virtualbox.org/ then click on downloads.

Once you have done that, you would want to go to Ubuntu's main website and download the .iso file associated with Ubuntu. That can be found here: http://www.ubuntu.com/desktop

Let me know if you need anything else.

I need your opinion on something. My PC fell and the hard disk started making this clicking sound, I think they call it the click of death. I have very important files in it and I didn't back them up. What do you suggest I should do?
