What is Linux File System? Easy Guide

By on 4 Kasım 2017 in GNU/Linux

As we’ve talked about Linux on the previous post and we have chosen the best Linux distro, also we’ve learned how to install Linux. Today we will discuss the Linux file system. What Is Linux File System? Linux File System or any file system generally is a layer which is under the operating system that handles the positioning of your data on the storage, without it; the system cannot knows which file starts from where and ends where. Even if you find any unsupported file system type. You can even download a software that can deal with it. So what are Linux file system types? When you try to install Linux you will see that Linux offers many file systems like these:

Continue Reading →

Ext, Ext2, Ext3, Ext4, JFS, XFS, btrfs and swap

So what are these file systems that Linux offers?

Ext: old one and no longer used due to limitations.

Ext2: first Linux file system that allows 2 terabytes of data allowed.

Ext3: came from Ext2, but with upgrades and backward compatibility.

The only problem about it that the servers don’t use this kind of file system because this file system doesn’t support file recovery or disk snapshots.

Ext4: faster and allow large files with significant speed.

It is a very good option for SSD disks and you notice when you try to install any Linux distro that this one is the default file system that Linux suggests.

JFS: old file system made by IBM. It works very well with small and big files, but it failed and files corrupted after long time use, reports say.

XFS: old file system and works slowly with small files.

Btrfs: made by Oracle. It is not stable as Ext in some distros, but you can say that it is a replacement for it if you have to. It has a good performance.

You may notice From the comparison above  that Ext4 is the best Linux File System

 Top Level Explanation

Now you know what file system Linux is and its types. So what is inside that filesystem, I mean from the top level.

You may come from Windows, and Windows has partitions like C:\ and D:\, you can install Windows on any of these partitions, usually C:\.

What about Linux File System Structure?

Well, if you navigate to the root partition which is / you’ll see the Linux File System hierarchy.

Most distros have the same structure with some little difference between distros.

Linux File System Directories

/bin: Where Linux core commands reside like ls, mv.

/boot: Where boot loader and boot files are located.

/dev: Where all physical drives are mounted like USBs DVDs.

/etc: Contains configurations for the installed packages.

/home: Where every user will have a personal folder to put his folders with his name like /home/likegeeks.

/lib: Where the libraries of the installed packages located since libraries shared among all packages

unlike windows, you may find duplicates in different folders.

/media: Here is the external devices like DVDs and USB sticks are mounted and you can access their files from here.

/mnt: Where you mount other things Network locations and some distros you may find your mounted USB or DVD.

/opt: Some optional packages are located here and this is managed by the package manager.

/proc: Because everything on Linux is a file, this folder for processes running on the system,

and you can access them and see much info about the current processes.

/root: The home folder for the root user.

/sbin: Like /bin, but binaries here are for root user only.

/tmp: Contains the temporary files.

/usr: Where the utilities and files shared between users on Linux.

/var: Contains system logs and other variable data.

Now you have a good idea about what the Linux file system is.

Choosing the right file system can lead you to the best performance, so choose the best.

How To Install Linux Step-By-Step

By on 4 Kasım 2017 in GNU/Linux İpuçları

After you’ve chosen the Best Linux Distro, now it’s the time to know how to install Linux. If you want to install Linux, there are 2 ways to do that: The first way is to download the Linux distribution you want and burn it into a DVD or USB stick and boot your machine with it and complete the installation process. The second way is to install it virtually on a virtual machine like VirtualBox or VMware without touching your Windows or Mac system, so your Linux system will be contained in a window you can minimize and continue working on your real system. For me, I prefer VirtualBox, it’s free and runs very fast on my PC than VMware, and support installing Windows, Linux and Mac OS with all versions. Let’s choose any Linux distro and install it using both 2 ways. I’m going to choose Linux mint, they call it the Mac OS of Linux. It is a good distro for personal use. The version we are going to install is 18.1 “Serena” at the time of writing that article.

Continue Reading →

Go to this link and download it:

https://www.linuxmint.com/download.php

I prefer the Cinnamon desktop version it is promising and elegant.

Once you download the ISO file, you will have to burn it on DVD or the easy way, copying it on a USB stick using a program called universal USB installer, you can download this program from this link:

https://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/

After downloading the program, open it and choose from the list the distro you want to install, in our case we will choose Linux mint.

Make sure that you put your memory stick on the computer and click next and wait till the copying process is finished.

how to install linux using usb
how to install Linux using USB

how to install linux mint

install linux choose iso

Now Finally we click create to create bootable USB

create bootable usb install linux

And now you can boot with this memory stick.

Then Restart your PC and go to BIOS settings and select boot options and make sure that the USB is the first option, then save your BIOS settings and reboot.

boot linux

Then it will show the installation screen, press Enter and it will load the live CD content.

install linux boot menu

Now the desktop should appear like that:

linux boot complete

Click install Linux mint

Then choose the language used for installation.

choose language

install third party

Then choose the installation type, and TAKE CARE if you are installing Linux on a disk that contains other operating systems, you MUST choose the option called something else.

delete partitions

If you are installing it on a new disk, choose the option Erase disk.

Linux requires 2 partitions to work, the root partition and the swap partition.

Now we will create them by clicking the plus button and choose about 12 GB or more as you need but not less than that for root partition, and choose mount type as / which stands for root and of course format will be Ext4.

linux create partitions

Now we create a swap partition, choose the remaining free space and click the plus button and choose swap area as shown:

create root partition

choose free space

Then Create the swap area:

create swap area

Then click install now and agree about writing changes to disk:

click install linux

confirm install

Now you choose the time zone and click continue the choose the language:

choose timezone

choose linux language

Now you write your username and password and click continue:

choose username

Finally, installation started:

linux installlation started

After finishing the installation, it will prompt you to reboot the machine and remove the installation media whether it is a DVD or USB.

linux installation finished

And yes, this is how to install Linux on Physical machine.

linux welcome screen

linux start menu

The second way it to install Linux is to install it on VirtualBox First download VirtualBox from here:

https://www.virtualbox.org/wiki/Downloads

There are 2 ways to use Linux on VirtualBox:

The first way is easy, it like the normal installation process

Open VirtualBox and click new and choose Linux and Ubuntu 64:

linux virtualbox create vm

Then choose the RAM required not less than 1 GB and choose the disk file type or leave it as VDI and dynamically allocated and the size not less than 12 GB and hit ok.

linux virtualbox assign ram

linux virtualbox hdd type

linux virtualbox hdd file

linux virtualbox dynamic allocated
Then file location for disk to be used

linux virtualbox hdd size

So now the VirtualBox is created, we just need to make it boot from the DVD that we’ve downloaded.

Choose from settings > Storage and choose the ISO image and click OK.

linux virtualbox settings
Then choose the iso image
linux virtualbox boot iso
Then Click start

linux virtualbox start

After loading the desktop, click install Linux mint and the rest of the steps are the same as the above mentioned without any change, And this is how to install Linux on a virtual machine.

CMake 3.9.5 duyuruldu

By on 4 Kasım 2017 in Programlama

Çapraz platform, açık kaynak kodlu, derleyiciden bağımsız bir biçimde yazılım oluşturma sürecini yöneten bir yazılım olan CMake’in 3.9.5 sürümü, Robert Maynard tarafından duyuruldu. CMake 3.9.5’i duyurmaktan gurur duyduğunu söyleyen Maynard; destek sunan herkese teşekkür ettiklerini ifade etti. Birden çok kütüphaneye dayanan uygulamaları ve dizin hiyerarşilerini destekleyen CMake; make, Apple Xcode ve Microsoft Visual Studio yerleşik yapı ortamlarıyla birlikte kullanılabiliyor. CMake’in kendi sisteminde yalnızca C++ derleyicisi gerektiren minimum bağımlılıkları vardır. CMake’in bir diğer güzel özelliği, bir grafik editörle kullanılmak üzere tasarlanmış bir önbellek dosyası oluşturmasıdır. Çapraz platform ortamına duyulan ihtiyaç nedeniyle, 1999’da geliştirilmeye başlanan CMake; United States National Library of Medicine tarafından finanse edilmektedir. İlk olarak 2000 yılında uygulanmaya giren CMake; 2001’de daha da gelişti. CMake 3.9.5 hakkında daha ayrıntılı bilgi edinmek için sürüm duyurusunu inceleyebilirsiniz.

Kuşkusuz, bu trafiğin şöyle bir dezavantajı da vardır. Birçok sitenin açılması çok uzun sürebilmektedir. Ancak, kullanıcı .onion uzantılı web sitesini yayınlayarak bu sayede Tor Browser üzerinden yayınladığı siteye girişin hızlı olmasını sağlayabilir. Ayrıca bu siteye normal browserlar ile erişilemeyecektir, siteye yalnızca Tor Browser kullananlar ulaşabileceklerdir. Yani mükemmel bir şekilde gizlenmiş bir web sayfasıdır söz konusu olan. Tor Browser 7.0.9 edinmek için aşağıdaki linkten yararlanabilirsiniz.
