You might be using many popular operating systems like Apple, Windows but here we will pick \u2018Linux\u2019 – what it is and what benefits it offer over other OS. <\/span><\/p>\n

So, Let\u2019s get started.<\/span><\/p>\n

Linux \u2013 What and Who?<\/b><\/span><\/p>\n

\n

\n

Linux is an operating system or kernel. It\u2019s idea was given by young & bright Linus Torvalds when he was computer science student. In those days, he used to work on UNIX OS and thought of improving it. His suggestions were rejected, so, he decided to launch an OS with modifications suggested by its users.<\/span><\/p>\n

Linus devised it and named \u2018Linux\u2019 around 1991. Now, he needed programs which can run on it. The time passed and he started collaborating with other programmers which gave rise to Linux \u2013 one of the most love and open source OS options available today!<\/span><\/p>\n

What is Linux Distribution?<\/b><\/span><\/p>\n

\n

\n

Linux is free to use kernel for programmers, profit and non-profit organizations. They exploit Linux for creating Operating system to satisfy their individual requirements. <\/span><\/p>\n

Many organizations keep Linux OS private and many other make variations of Linux available to public. These types\/versions\/kinds of Linux OS are called as <\/span>Distributions.<\/b><\/span><\/p>\n

Hundreds of distributions are available today (also called Linux Distro) – <\/b><\/span><\/p>\n

Arch<\/span><\/p>\n

CentOS<\/span><\/p>\n

Debian<\/span><\/p>\n

Fedora<\/span><\/p>\n

LinuxMint<\/span><\/p>\n

Ubuntu<\/span><\/p>\n

But, naming, which is the best Linux Distribution is different as each one of them is made to suit different purposes. <\/span><\/p>\n

Also, There are various methods to install Linux in your system – <\/b><\/span><\/p>\n

USB stick<\/span><\/p>\n

Live CD<\/span><\/p>\n

Virtual Installation<\/span><\/p>\n

Making a Big Switch…<\/b><\/span><\/p>\n

\n

\n

Here we discuss about things that get changed when you switch from Windows or Mac OS to Linux. Unlike Windows, where files are stored in folders under drives like C: D: etc, in Linux files are ordered in the hierarchy. <\/span><\/p>\n

Types of Files used in Linux & Unix <\/b><\/span><\/p>\n

General files<\/span><\/p>\n

Directory files<\/span><\/p>\n

Device files<\/span><\/p>\n

3 Types of Users in Linux<\/b><\/span><\/p>\n

Regular<\/span><\/p>\n

Root<\/span><\/p>\n

Service<\/span><\/p>\n

And, the file convention used in Linux is case sensitive i.e. plain and PLAIN are 2 different files.<\/span><\/p>\n

Linux File Management<\/b><\/span><\/p>\n

\n

\n

You can either use CLI (Terminal) or GUI (File manager) for managing your files in Linux. Both have their relative advantages. <\/span><\/p>\n

For launching terminal, use dashboard or press shortcut key Ctrl+Alt+T. <\/span><\/p>\n

Various command used in Terminal File manager:<\/b><\/span><\/p>\n

cd or cd ~ (for navigating to home directory)<\/span><\/p>\n

cd.. (moving one level up)<\/span><\/p>\n

cd (moving to particular directory)<\/span><\/p>\n

cd\/ (moving to root directory)<\/span><\/p>\n

Must-Know Linux Commands<\/b><\/span><\/p>\n

\n

\n

If you know the right command, then, managing files become easy. So, here are the list of commands that you must know: <\/span><\/p>\n

ls, for listing files<\/span><\/p>\n

ls \u2013 R, for listing files in sub directories<\/span><\/p>\n

ls \u2013 a, for listing hidden files<\/span><\/p>\n

cat>filename, for creating new file<\/span><\/p>\n

cat filename, for displaying file content<\/span><\/p>\n

sudo, allowing users to run program with security privileges of superuser or root<\/span><\/p>\n

rm, for deleting files<\/span><\/p>\n

man, gives help information<\/span><\/p>\n

history, gives list of past commands<\/span><\/p>\n

clear, clears terminal<\/span><\/p>\n

mkdir, makes new directory<\/span><\/p>\n

mv, used to rename a directory<\/span><\/p>\n

Wrapping Up<\/b><\/span><\/p>\n

\n

\n

Thus, A Unix based Linux OS helps made all resources associated with your computer system \u2013 files, directories, etc. <\/span><\/p>\n

It is free, open source and licensed under GPLv2. Hope, now, you\u2019ve got basic idea of Linux OS \u2013 what, why, how\u2019s…..!<\/span><\/p>\n
