Windows is not the only operating system in the world! But, it is one of the most widely used operating systems due to its user-friendly interface. Apart from Windows, there are various other operating systems such as MacOS, Android, Ubuntu, etc.

This is a Linux distro, based on Debian. It was initially released in the year 2004 and is still being used by a number of people around the world! The default installation of Ubuntu comes with several other software such as LibreOffice, Firefox, Thunderbird, Transmission, etc. Also, there are several pre-installed games such as Sudoku and chess.

You can also use this command to move a file from one location to another. For example, to move log.txt to /home/folder, run the command ‘mv log.txt /home/folder.’

To copy a file from one directory to another, you can use the ‘cp‘ command. For example, cp log.txt /home/folder will create a copy of log.txt in the /home/folder directory.

To remove a file, one can make use of the ‘rm‘ command. In this command, you are expected to enter a filename as an argument. For example, rm log.txt will remove the text file, if present in the current directory, while rm /home/folder/test/log.txt will remove the text file present in the test directory.

To remove a directory, use the -r command line option with the rm command. For example, rm -r /home/folder/test/ will delete the test directory with all its subdirectories and files.

#4 How to search for a file?

To search for a file, you can make use of ‘find‘ command. You need to enter the directory path and filename along with this command. If you do not specify the directory, find command searches for your file in the present working directory.

#5 SuperUserDo (sudo).

This command sudo is an abbreviation for SuperUserDo. You will have to use it while typing commands which require permission from the root (if you are not a root user). All you need to do is, simply place this command before the command that you want to execute with root permission.

#6 Power-off computer (Poweroff).

This command shows you to power off your computer using the Ubuntu terminal. You can use this command as a substitute for the traditional method of turning off your computer.

Top 10 Best Linux Distro of 2017 | For Developers, Beginners
Top 10 Best Linux Distro of 2019 | For Developers, Beginners

Linux is an open-source operating system similar to UNIX and is free for download and use. Linux is cross-platform and thus can be installed on PCs, laptops, mobile phones, video game consoles, TVs, netbooks, cameras, DVD players, planes, servers, Large Hadron Collider and supercomputers. The popular mobile operating system Android is based on a Linux kernel. The operating system can be redistributed, expanded and used completely free of charge and since it is open source, updates are quickly released by users and bugs are squashed by the community.

Linux has many different variants called flavors or distros built by the community. Each distro offers specific features to the user such as programs for server maintenance or security testing. Here are some distros we think are worth taking a look at:

#1 Kali Linux: Best Linux Distro

Kali Linux is a Linux distro developed for penetration testers. It offers a broad range of tools and programs for testing security of a network. It also contains tools to hack wireless networks and perform man-in-the-middle attacks. Several programs also offer password cracking, network mapping, wiretap, packet sniffing, and port scanning functionality.

#2 SteamOS: Best Debian Distro

SteamOS is based on the Debian distro and is designed to run games from Steam and Valve. It lacks essential programs like a file browser and media manager and is meant only to be used on gaming machines. It is being worked on for everyday use. It has updated third-party drivers and can handle switching from games to Steam and SteamOS. They are in talks with Twitch for live streaming without the use of any other software. It has a built-in Steam store, and so installing games is easy.

#3 Remix OS: Easy Linux Distros

Want to use Android on PC but don’t want to install emulators? Then this is the right distro for you. Remix OS brings the functionality of Android to your PC by allowing you to access over 2 million apps on the Play Store. It runs on Android Marshmallow and is currently available on hardware made by Jide, but you can also download it for machines running x86 or ARM architectures.

#4 Chromium OS

ChromeOS is the commercial version of this distro which ships with Chromebooks. ChromiumOS is open source and is light on the hardware. Google developed it exclusively to work with web applications such as Google Slides and Google Spreadsheet. The drawback of this operating system is that it becomes less useful without a good internet connection.

#5 ElementaryOS

If you want your computer to run MacOS but don’t have a Mac then this distro might interest you. Although it is not MacOS, it looks similar to it. It focuses on an easy user interface with functionality and minimal documentation. You cannot create shortcuts on the desktop but can run apps from the app drawer. You can use this as your daily driver if you don’t mind the glitches and bugs.

#6 Mint

One of the more user-friendly distros, Mint comes with many popular free packages such as LibreOffice and Firefox browser. It is updated every six months, and new features are integrated. If you are new to Linux and don’t know which distro to use, you can reliably use this one. Mint comes in two flavors – Debian and Ubuntu, but the differences between them are not noticeable.


RHEL or Red Hat Enterprise Linux claims to offer military-grade security for networks with 99.99% of uptime. It provides services such as network firewalls to isolate applications and protect users from breaches and intrusions. You can safely deploy RHEL in your virtual or cloud networks. Although it is now discontinued, many new distros like CentOS derive inspiration from it.

#8 Raspbian

If you have used Raspberry Pi computers before you might want to look at this. Raspbian is made bearing in mind the hardware restrictions of the single chip Raspberry Pi computer. It is derived from Linux Debian and uses an LXDE environment for low power and resource consumption.

#9 Ubuntu: Best Linux Distro

Ubuntu is a most used operating system for hacking and programming. This is one of the best Linux distros that you can use instead of kali and windows. The support provided by the Canonical and open source is just awesome. Ubuntu is one of the highlights of Linux desktop situation.

#10 Zorin OS

Another best Linux distributions that you can use right next to your windows. While one may claim that allow it to be widely used and Canonical has worked hard to produce Ubuntu, other operating system programmers have committed themselves to make among the Linux distros. Zorin OS is another player who has concentrated itself to reliability and user-friendliness.
