The order in which to find and install software on Linux.
1. Desktop computer “Ubuntu Software Center” search installation
Ubuntu Software Center, or simply Software Center, is a discontinued high-level graphical front end for the APT/dpkg package management system. It is free software written in Python, PyGTK/PyGObject based on GTK.
The program was created for adding and managing repositories, as well as Ubuntu Personal Package Archives (PPA) and on Ubuntu, the Ubuntu Software Center also allowed users to purchase commercial applications.
Development was ended in 2015 and in Ubuntu 16.04 LTS. It was replaced with GNOME Software.
2. Synaptic search installation
Synaptic is a GTK-based graphical user interface for the APT package manager used by the Debian Linux distribution and its derivatives. Synaptic is usually used on systems based on deb packages but can also be used on systems based on RPM packages. It can be used to install, remove and upgrade software packages and to add repositories.
3. Ubuntu Terminal
Terminal
Working at the command line is not as daunting a task as you would think. There is no special knowledge needed to use the command line as it is a program like everything else. Most things in Linux can be done using the command line. Although there are graphical tools for most programs, sometimes they are just not enough. This is where the command line comes in handy.
The terminal is often called the command prompt or the shell. In days gone by, this was the way the user interacted with the computer; however, Linux users have found that the use of the shell can be quicker than a graphical method and still holds some merit today. Here you will learn how to use the terminal.
The original use of the terminal was as a file browser, and indeed it is still used as a file browser. You can use the terminal as a file browser to navigate your files and undo the changes that have been made.
Starting the Terminal
The Konsole can be started by choosing menu->System->Konsole (Terminal Program) from the Desktop menu system.
Common Commands
View Directories: – ls
The ls (LiSt) lists files in different colors with full formatted text.
$ sudo ls
Create Directories: – mkdir (directory name)
The mkdir (MaKeDIRectory) command will create a directory.
$ sudo mkdir directory name
Change Directories: – cd (/directory/location)
The cd (Change Directory) command will change from your current directory to any directory you specify.
$ sudo cd
$ sudo cd /directory/location
Copy Files/Directories: – cp (file or directory name) (to directory or filename)
The cp (CoPy) command will copy any files you specify. The cp -r command will copy any directories you specify.
cp folder
$ sudo cp -r /download/wordpress/ /media/user/sdb/
cp file
$ sudo cp /download/wordpress/index.html /media/user/sdb/
Copy only the contents of the folder. Remember this command as it will be useful when installing the WordPress application program on a web server.
$ sudo cp -a /download/wordpress/. /var/www/html
Free Web Server
How to start a free web server.
Remove Files/Directories: – rm (file or directory name)
The rm (ReMove) command will delete any filename you specify. The rm -r command will remove any directory you specify, and all its contents.
rm folder
$ sudo rm -r /download/wordpress/
Move/Rename Files/Directories: – mv (file or directory name)
The mv (MoVe) command will move/rename any file or directory you specify.
rm file
$ sudo rm /download/wordpress/index.html
Find Files/Directories: – locate (file or directory name)
$ sudo locate file
$ sudo locate directory name
The locate command will search for any filename you specify. It uses an index of the files on your system to work quickly. To update this index, run the command sudo updatedb. This command is run automatically each day if you leave your computer on. It needs to be run with administrative privileges “Root And Sudo”.
Command input example
$ sudo apt update
$ sudo apt upgrade
$ sudo apt install gufw
$ sudo apt remove gufw
$ sudo apt autoremove
$ sudo nano

[sudo] User password:
“sudo”?
sudo is a program for Unix-like computer operating systems that enables users to run programs with the security privileges of another user, by default the superuser. It originally stood for “superuser do”, as that was all it did, and it is its most common however, the official Sudo project page lists it as “su ‘do’ ”. The current Linux manual pages for su define it as “substitute user”, making the correct meaning of sudo “substitute user, do”, because sudo can run a command as other users as well.
Unlike the similar command su, users must, by default, supply their own password for authentication, rather than the password of the target user. After authentication, and if the configuration file (typically /etc/sudoers) permits the user access, the system invokes the requested command. The configuration file offers detailed access permissions, including enabling commands only from the invoking terminal; requiring a password per user or group; requiring re-entry of a password every time or never requiring a password at all for a particular command line. It can also be configured to permit passing arguments or multiple commands.
Simply put, a computer user.

To make it easy for beginners to understand and to prevent malfunctions, they are separated in stages. Difference between graphical interface “GUI” and “CUI” command line interface.
The “Microsoft” and “Macintosh” graphical interfaces appeared in the “Linux” command line era and fascinated users all over the world.
In “Linux“, access rights can be determined for each file, making it difficult to easily hack from outside.
On the other hand, “Microsoft” and “Macintosh” have executable file names such as “.exe” “.app” that are easy to guess from external networks. Having a large number of active users makes it easy to create hacking tools.
The reason why “Linux” is called strong in security.

“Nissan Fairlady Z”
The ultimate car design “Z” “Sexy Spider” The first car I bought.
Flowing and streamlined. A naughty body reminiscent of a woman.
Nissan Fairlady Z (S30)
The Nissan S30, sold in Japan as the Nissan Fairlady Z and in other markets as the Datsun 240Z, then later as the 260Z and 280Z, is a grand tourer produced by Nissan (Datsun in USA) from 1969 until 1978. The S30 was conceived of by Yutaka Katayama, the President of Nissan Motor Corporation U.S.A., and designed by a team led by Yoshihiko Matsuo, the head of Nissan’s Sports Car Styling Studio. It is the first car in Nissan’s Z series of sports cars.
Aiming to compete directly with established European sports cars, Datsun priced the new 240Z within $200 of the British MGB-GT in the United States, a five-year-old design that showed its age. The 240Z’s styling, engineering, relatively low price, and impressive performance resonated with the public, received a positive response from both buyers and the motoring press, and immediately generated long waiting lists.
As a halo car, the 240Z broadened the acceptance of Japanese car-makers beyond their economic image. Datsun’s growing dealer network—compared to limited production imported sports cars manufactured by Jaguar, BMW, Porsche, Alfa Romeo, and Fiat—ensured both easy purchase and ready maintenance.
All variants of the S30 have four-wheel independent suspension consisting of MacPherson struts in the front (borrowed from the Nissan Laurel C30) and Chapman struts in the back. Front disc brakes and rear drums were standard.
The 240Z used twin SU-style Hitachi one-barrel side-draft carburettors. These were replaced on the 260Z with Hitachi one-barrel side-draft carburettors beginning with model year 1973 to comply with emissions regulations, resulting in diminished overall performance. A Bosch-designed L-Jetronic electronic fuel injection was added to US market 280Zs in 1975 to compensate.
Continuing through the 1975–1978 model years, markets outside of the United States (and Japan, which only offered the 2-liter engine from 1974) still received the 260Z coupé and 2+2. The S30 240Z is unrelated to the later 240SX, which is sold as the Silvia in Japan.
The Fairlady Z was introduced in late 1969 as a 1970 model, with the L20 2.0-liter straight-six SOHC engine, rear-wheel drive, and a stylish coupe body. In Japanese specs the engine, based on the Datsun 510’s four-cylinder, produced 130 PS (96 kW; 128 hp) JIS and came with a four- or a five-speed manual transmission. For 1973, power of the carburetted engine dropped to 125 PS (92 kW; 123 hp) to meet stricter regulations. In Japan, the Fairlady was exclusive to Nissan Japanese dealerships called Nissan Bluebird Stores. Japanese buyers could also get the L24-engined Fairlady 240Z model (HS30), although the larger engine placed it in a considerably higher tax category. The Japanese-spec 2.4-liter engine produces a claimed 150 PS (110 kW; 148 hp) JIS at 5,600 rpm but was discontinued in 1973 as sales had dropped considerably as a result of the fuel crisis, and so until the August 1978 introduction of the Fairlady 280Z only two-liter Fairladys were available.

Sexy Spider knows the era “1997”
Users who Sexy Spider knows the era “1997” are not familiar with Linux. This is how to install an application software program.
1. Desktop computer “Ubuntu Software Center” search installation
2. Synaptic search installation
3. Ubuntu Terminal
Linux Pre-installed software
Firefox
Mozilla Firefox, or simply Firefox, is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. It uses the Gecko rendering engine to display web pages, which implements current and anticipated web standards. Firefox is available for Windows 10 or later versions, macOS, and Linux. Its unofficial ports are available for various Unix and Unix-like operating systems, including FreeBSD, OpenBSD, NetBSD, illumos, and Solaris Unix. It is also available for Android and iOS. However, as with all other iOS web browsers, the iOS version uses the WebKit layout engine instead of Gecko due to platform requirements. An optimized version is also available on the Amazon Fire TV as one of the two main browsers available with Amazon’s Silk Browser.
Firefox is the spiritual successor of Netscape Navigator, as the Mozilla community was created by Netscape in 1998, before its acquisition by AOL. Firefox was created in 2002 under the codename “Phoenix” by members of the Mozilla community who desired a standalone browser rather than the Mozilla Application Suite bundle. During its beta phase, it proved to be popular with its testers and was praised for its speed, security, and add-ons compared to Microsoft’s then-dominant Internet Explorer 6. It was released on November 9, 2004, and challenged Internet Explorer’s dominance with 60 million downloads within nine months. In November 2017, Firefox began incorporating new technology under the code name “Quantum” to promote parallelism and a more intuitive user interface.
Firefox usage share grew to a peak of 32.21% in November 2009, with Firefox 3.5 overtaking Internet Explorer 7, although not all versions of Internet Explorer as a whole; its usage then declined in competition with Google Chrome. As of December 2023, according to StatCounter, it had a 6.7% usage share on traditional PCs (i.e. as a desktop browser), making it the fourth-most popular PC web browser after Google Chrome (62%), Safari (13%), and Microsoft Edge (11%).
Thunderbird
Mozilla Thunderbird is free and open-source email client software which also functions as a full personal information manager with a calendar and contactbook, as well as an RSS feed reader, chat client (IRC/XMPP/Matrix), and news client. Available cross-platform, it is operated by the Mozilla Foundation’s subsidiary MZLA Technologies Corporation. Thunderbird is an independent, community-driven project that is managed and overseen by the Thunderbird Council, which is elected by the Thunderbird Community. The project strategy was originally modeled after that of Mozilla’s Firefox web browser and is an interface built on top of that web browser.
LibreOffice
LibreOffice (/ˈliːbrə/) is a free and open-source office productivity software suite, a project of The Document Foundation (TDF). It was forked in 2010 from OpenOffice.org, an open-sourced version of the earlier StarOffice. The LibreOffice suite consists of programs for word processing, creating and editing spreadsheets, slideshows, diagrams, and drawings, working with databases, and composing mathematical formulae. It is available in 115 languages. TDF does not provide support for LibreOffice, but enterprise-focused editions are available from companies in the ecosystem.
LibreOffice uses the OpenDocument standard as its native file format but supports formats of most other major office suites, including Microsoft Office, through a variety of import and export filters.
LibreOffice is available for a variety of computing platforms, with official support for Microsoft Windows, macOS and Linux and community builds for many other platforms. Ecosystem partner Collabora uses LibreOffice upstream code and provides apps for Android, iOS, iPadOS and ChromeOS. LibreOffice is the default office suite of the most popular Linux distributions.
LibreOffice Online is an online office suite that includes the applications Writer, Calc, and Impress and provides an upstream for projects such as commercial Collabora Online.
It is the most actively developed free and open-source office suite, with approximately 50 times the development activity of Apache OpenOffice, the other major descendant of OpenOffice.org, in 2015.
The project was announced, and a beta was released on September 28, 2010. In the nine months between January 2011 (the first stable release) and October 2011, LibreOffice was downloaded about 7.5 million times. In 2015, the project claimed 120 million unique downloading addresses from May 2011 to May 2015, excluding Linux distributions, with 55 million of those being from May 2014 to May 2015. The Document Foundation estimates that there are 200 million active LibreOffice users worldwide. Approximately 25% are students and 10% are Linux users; the latter usually find LibreOffice part of their preferred distribution.

Live Chat/Spy Camera/SNS
Social networking service.
social networking service or SNS (sometimes called a social networking site) is a type of online social media platform which people use to build social networks or social relationships with other people who share similar personal or career content, interests, activities, backgrounds or real-life connections.
Social networking services vary in format and the number of features. They can incorporate a range of new information and communication tools, operating on desktops and on laptops, on mobile devices such as tablet computers and smartphones. This may feature digital photo/video/sharing and diary entries online (blogging). Online community services are sometimes considered social-network services by developers and users, though in a broader sense, a social-network service usually provides an individual-centered service whereas online community services are groups centered. Generally defined as “websites that facilitate the building of a network of contacts in order to exchange various types of content online,” social networking sites provide a space for interaction to continue beyond in-person interactions. These computer mediated interactions link members of various networks and may help to create, sustain and develop new social and professional relationships.
Social networking sites allow users to share ideas, digital photos and videos, posts, and to inform others about online or real-world activities and events with people within their social network. While in-person social networking – such as gathering in a village market to talk about events – has existed since the earliest development of towns, the web enables people to connect with others who live in different locations across the globe (dependent on access to an Internet connection to do so). Depending on the platform, members may be able to contact any other member. In other cases, members can contact anyone they have a connection to, and subsequently anyone that contact has a connection to, and so on. The success of social networking services can be seen in their dominance in society today, with X (formerly Twitter) being referred to as “world town square that offers its users a real-time activity, like contacting anyone including friends, sharing images, videos and texts in form of “tweets”. Facebook having a massive 2.13 billion active monthly users and an average of 1.4 billion daily active users in 2017. LinkedIn, a career-oriented social-networking service, generally requires that a member personally know another member in real life before they contact them online. Some services require members to have a preexisting connection to contact other members. With COVID-19, Zoom, a videoconferencing platform, has taken an integral place to connect people located around the world and facilitate many online environments such as school, university, work and government meetings.
The main types of social networking services contain category places (such as age or occupation or religion), means to connect with friends (usually with self-description pages), and a recommendation system linked to trust. One can categorize social-network services into four types:
・ socialization social network services used primarily for socializing with existing friends or users (e.g., Facebook, Instagram, Twitter/X)
・ online social networks are decentralized and distributed computer networks where users communicate with each other through Internet services.
・ networking social network services used primarily for non-social interpersonal communication (e.g., LinkedIn, a career- and employment-oriented site)
・ social navigation social network services used primarily for helping users to find specific information or resources (e.g., Goodreads for books, Reddit)
There have been attempts to standardize these services to avoid the need to duplicate entries of friends and interests (see the FOAF standard). A study reveals that India recorded world’s largest growth in terms of social media users in 2013. A 2013 survey found that 73% of U.S. adults use social-networking sites.
Spy Camera.
hidden camera or spy camera is a camera used to photograph or record subjects, often people, without their knowledge. The camera may be considered “hidden” because it is not visible to the subject being filmed, or is disguised as another object. Hidden cameras are often considered a surveillance tool.
The term “hidden camera” is commonly used when subjects are unaware that they are being recorded, usually lacking their knowledge and consent; the term “spy camera” is generally used when the subject would object to being recorded if they were aware of the camera’s presence. In contrast, the phrase “security camera” refers to cameras that are visible and/or are accompanied by a warning notice of their presence, so the subject is aware of the camera’s presence and knows they are being filmed.
Live Chat.
LiveChat is an online customer service software with online chat, help desk software, and web analytics capabilities.
It was first launched in 2002 and is currently developed and offered in a SaaS (software as a service) business model by LiveChat Software S.A.
Companies use LiveChat as a single point of contact to manage from one software all customer service and online sales activities that normally are provided using channels (chat, email and social media) and multiple tools.
Cheese
Cheese is the former default webcam application for the GNOME desktop, i.e. an application to handle UVC streams over Video4Linux.

RSS feed reader?
“Website viewing application programs” were popular in the 1900s. In the 2000s, “SNS” became mainstream, and “RSS” and “FEED” and ”Atom” disappeared from almost all “WWW” and “World Wide Website Network” and “Web browsers”, “Internet“.
For the first time, I called the “website” HyperText Markup Language, a technology mainly written in “HTML”. Established “Website” and “Web Server” in 1997. They were playing with programs written in the “CGI” language, such as the “counter” that displays the number of visitors, and the communication programs “BBS” and “chat”.
In the 2000s, “BLOG” written in the “PHP” language became mainstream, and “RSS” and “FEED” and “Atom” and “Ping” programs were born. Sexy Spider Web site is created using WordPress.
As of 2024, “Youtube” is a program that combines “SNS” Social Networking Service and streaming technology that can be used even if you do not have your own website or domain. Subdomain types, external networks, and third-party programs have become mainstream.
I see “idiots” who mistakenly think that they have become “influencers” or “popular people” on the “Youtube” “SNS” domain. Subdomains of “account name@Youtube.com” and “account name@SNS.com”.
“Youtube” is an application program provided by “Google” that distributes “Video” and “Music”, but it is a common story that the web service is suddenly terminated because it is no longer profitable.
Unless a web service is provided by you and is located under “account name@yourdomain.com” under your domain, it will never be yours.
trend “Chat GDP”
We trained a model called ChatGPT that interacts conversationally. The conversational format allows ChatGPT to answer follow-up questions, admit mistakes, challenge incorrect assumptions, and deny inappropriate requests. Openai development.
If you are using “WordPress” as your platform, these “application program” functions can be completed with “plugins.”
No matter how good an application program is, it is meaningless if there is no place to install it. “Domain” and “web server” required. A “website” becomes a space that can be distributed to users around the world.

Minecraft has become the best-selling video game in history, with over 300 million copies sold and nearly 140 million monthly active players as of 2023. It has been ported to several platforms.
1. Desktop computer “Ubuntu Software Center” search installation
In Minecraft, players explore a blocky, pixelated procedurally generated, three-dimensional world with virtually infinite terrain. Players can discover and extract raw materials, craft tools and items, and build structures, earthworks, and machines. Depending on their chosen game mode, players can fight hostile mobs, as well as cooperate with or compete against other players in the same world. Game modes include a survival mode (in which players must acquire resources to build in the world and maintain health), creative mode (in which players have unlimited resources and the ability to fly), spectator mode (in which players can fly, go through blocks, and enter the bodies of other players and entities), adventure mode (in which players have to survive without being able to build and place blocks) and hardcore mode (in which the difficulty is set to Hard and dying causes the player to lose their ability to play on that world). The game’s large community also offers a wide variety of user-generated content, such as modifications, servers, skins, texture packs, and custom maps, which add new game mechanics and possibilities.
Minecraft has received critical acclaim, winning several awards and being cited by some as one of the greatest video games ever created; social media, parodies, adaptations, merchandise, and the annual Minecon conventions played prominent roles in popularizing the game. The game has also been used in educational environments to teach chemistry, computer-aided design, and computer science. In 2014, Mojang and the Minecraft intellectual property were purchased by Microsoft for US$2.5 billion. Several spin-offs have also been made, including Minecraft: Story Mode, Minecraft Earth, Minecraft Dungeons, and Minecraft Legends. In addition, a live-action film of the same name is scheduled for a theatrical release in 2025.

GNOME
GNOME (/ɡəˈnoʊm, ˈnoʊm/), originally an acronym for GNU Network Object Model Environment, is a free and open-source desktop environment for Linux and other Unix-like operating systems.
Many major Linux distributions, including Debian, Fedora Linux, Ubuntu, Red Hat Enterprise Linux, and SUSE Linux Enterprise distribute GNOME as their default desktop environment; it is also the default in Oracle Solaris, a Unix operating system.
GNOME is developed by the GNOME Project, which is composed of both volunteers and paid contributors, the largest corporate contributor being Red Hat. It is an international project that aims to develop frameworks for software development, to program end-user applications based on these frameworks, and to coordinate efforts for the internationalization, localization, and accessibility of that software.
KDE
KDE is an international free software community that develops free and open-source software. As a central development hub, it provides tools and resources that allow collaborative work on this kind of software. Well-known products include the Plasma Desktop, KDE Frameworks, and a range of cross-platform applications such as Amarok, digiKam, and Krita that are designed to run on Unix and Unix-like operating systems, Microsoft Windows, and Android.
GTK
GTK (formerly GIMP ToolKit and GTK+) is a free software cross-platform widget toolkit for creating graphical user interfaces (GUIs). It is licensed under the terms of the GNU Lesser General Public License, allowing both free and proprietary software to use it. It is one of the most popular toolkits for the Wayland and X11 windowing systems.
The GTK team releases new versions on a regular basis. GTK 4 and GTK 3 are maintained, while GTK 2 is end-of-life. GTK1 is independently maintained by the CinePaint project.
Wayland
Wayland is a replacement for the X11 window system protocol and architecture with the aim to be easier to develop, extend, and maintain.
Wayland is the language (protocol) that applications can use to talk to a display server in order to make themselves visible and get input from the user (a person). A Wayland server is called a “compositor”. Applications are Wayland clients.
Wayland also refers to a system architecture. It is not just a server-client relationship between a compositor and applications. There is no single common Wayland server like Xorg is for X11, but every graphical environment brings with it one of many compositor implementations. Window management and the end user experience are often tied to the compositor rather than swappable components.
A core part of Wayland architecture is libwayland: an inter-process communication library that translates a protocol definition in XML to a C language API. This library does not implement Wayland, it merely encodes and decodes Wayland messages. The actual implementations are in the various compositor and application toolkit projects.
Wayland does not restrict where and how it is used. A Wayland compositor could be a standalone display server running on Linux kernel modesetting and evdev input devices or on many other operating systems, or a nested compositor that itself is an X11 or Wayland application (client). Wayland can even be used in application-internal communication as is done in some web browsers.
Part of the Wayland project is also the Weston reference implementation of a Wayland compositor. Weston can run as an X client or under Linux KMS and ships with a few demo clients. The Weston compositor is a minimal and fast compositor and is suitable for many embedded and mobile use cases.
X Window System
The X Window System (X11, or simply X) is a windowing system for bitmap displays, common on Unix-like operating systems.
X provides the basic framework for a GUI environment: drawing and moving windows on the display device and interacting with a mouse and keyboard. X does not mandate the user interface – this is handled by individual programs. As such, the visual styling of X-based environments varies greatly; different programs may present radically different interfaces.
X originated as part of Project Athena at Massachusetts Institute of Technology (MIT) in 1984. The X protocol has been at version 11 (hence “X11”) since September 1987. The X.Org Foundation leads the X project, with the current reference implementation, X.Org Server, available as free and open-source software under the MIT License and similar permissive licenses.
The GNU Operating System and the Free Software Movement

Conky is highly configurable and is able to monitor many system variables including the status of the CPU, memory, swap space, disk storage, temperatures, processes, network interfaces, battery power, system messages, e-mail inboxes, Arch Linux updates, many popular music players (MPD, XMMS2, BMPx, Audacious, etc.), weather updates, breaking news, and much more. Unlike system monitors that use high-level widget toolkits to render their information, Conky is drawn directly in an X window. This allows it to be configured such that it consumes relatively few system resources.
Conky was hailed as “one of the best maintained, and definitely one of the most useful, programs in the world of open source” in Linux Magazine.
It comes pre-configured in the default installation of Pinguy OS and CrunchBang Linux.

・ GRC’s DNS Benchmark
Utility to determine the exact performance of DNS nameservers.
1. Desktop computer “Ubuntu Software Center” search installation
GRC’s DNS Benchmark performs a detailed analysis and comparison of the operational performance and reliability of any set of up to 200 DNS nameservers (sometimes also called resolvers) at once. When the Benchmark is started in its default configuration, it identifies all DNS nameservers the user’s system is currently configured to use and adds them to its built-in list of publicly available “alternative” nameservers. Each DNS nameserver in the benchmark list is carefully “characterized” to determine its suitability — to you — for your use as a DNS resolver. This characterization includes testing each nameserver for its “redirection” behavior: whether it returns an error for a bad domain request, or redirects a user’s web browser to a commercial marketing-oriented page. While such behavior may be acceptable to some users, others may find this objectionable.

Mount the created RAID disk and make it usable.
This time, /mnt/raid1 will be the mount destination.
user@computername:~$ sudo su
[sudo] User password:
root@computername:/home/user#
mkdir -p /mnt/raid1
mount -t ext4 /dev/md0 /mnt/raid1
If the mount destination is displayed in Mounted on, it is working properly.

Automatically mount on reboot
If you reboot, the mount settings will be reset.
Since it is troublesome to configure the settings manually again, we will configure the settings to mount automatically when restarting.
Write the settings at the end of /etc/fstab as shown below.
$ sudo nano /etc/fstab
…
/dev/md0 /mnt/raid1 ext4 defaults 0 0
Points to note when restarting
When restarting, /dev/md0 is automatically changed to /dev/md127.
Mounting will fail if the device name is changed, so it is necessary to prevent the device name from changing.
Write the current RAID settings in the mdadm configuration file (/etc/mdadm/mdadm.conf).
user@computername:~$ sudo su
[sudo] User password:
root@computername:/home/user#
mdadm –detail –scan /dev/md0 >> /etc/mdadm/mdadm.conf

GNOME Disks
GNOME Disks is a graphical front-end for udisks. It can be used for partition management, S.M.A.R.T. monitoring, benchmarking, and software RAID (until v. 3.12). An introduction is included in the GNOME Documentation Project.
Disks used to be known as GNOME Disk Utility or palimpsest Disk Utility. Udisks was named DeviceKit-disks in earlier releases. DeviceKit-disks is part of DeviceKit which was planned to replace certain aspects of HAL. HAL and DeviceKit have been deprecated.
GNOME Disks has been included by default in several Linux distributions including Debian, Ubuntu, Linux Mint, Trisquel, Fedora, Red Hat Enterprise Linux and CentOS.
Linux Pre-installed software
Recently, large-capacity “HDD” have been sold cheaply, so the following commands are useful for “backup” and “duplication” purposes for those who do not need to incorporate RAID. If your “HDD” is not working properly, it is faster to replace it with a new “HDD” and perform a clean OS install. We recommend storing the OS startup “HDD” and important data “HDD” separately.
