Types of operating systems.

Operating systems normally include pre-loaded on almost any Computer you purchase. Many men and women use the operating system which comes with their computer, however it is possible to update or perhaps alter operating systems. The three most frequent operating systems for personal computers are Microsoft Windows, macOS, and Linux. A GUI enables you to use your mouse to click on icons, switches , and menus, and that which is clearly displayed on the display by means of a combo of images and text. Each operating system's GUI includes a different feel and look, so if you Switch to another operating system it might appear unfamiliar at first. However, modern operating systems have been made to be effortless to utilize , and the majority of the fundamental principles are exactly the same.

Microsoft established the Windows operating platform at the mid-1980s. There have been a number of distinct variants of Windows, but the latest ones are Windows 10 (published in 2015), Windows 8 (2012), Windows 7 (2009), along with Windows Vista (2007). Windows includes pre-loaded on many new PCs, which helps to ensure it is the hottest operating system on the planet.

MacOS (formerly called OS X) is a Lineup of operating systems made by Apple. It comes preloaded on all Macintosh computers, or Macs. A number of the specific models include Mojave (published in 2018), High Sierra (2017), and Sierra (2016). Based on StatCounter Global Stats, macOS users accounts for significantly less than 10 percent of international functioning systems--considerably lower than the percent of Windows users (greater than 80 percent ). 1 reason behind this is that Apple computers have a tendency to be costlier. But a lot of individuals do prefer the appearance and feel of macOS over Windows.

Linux (pronounced LINN-ux) is a household of open-source operating systems, so they may be altered and distributed by all around the globe. This differs from proprietary program such as Windows, which may only be altered by the organization that owns it. The benefits of Linux are that it's free, and there are several different distributions or variations you may select from. Based on StatCounter Global Stats, Linux users accounts for under 2 percent of international functioning systems. But most servers run Linux since it's relatively simple to personalize.

The operating systems we have been speaking about so much were created to operate on desktop and notebook computers. Mobile apparatus like telephones , tablets , and MP3 players Are distinct from desktop and notebook computers, so that they run operating systems that have been designed especially for mobile devices. From the screenshot below, you can view iOS running in an iPad. Operating systems for mobile devices normally are not as fully featured As those created for desktop and notebook computers, and they are not capable to Run each the exact same software. But, you can still perform a Great Deal of things Together, like watch videos, browse the net, manage your calendarand play games.

Boost Up Productivity in Bash - Tips and Tricks

Bash Tips and Tricks
by Antonio Riso

Introduction

When spending most of your day around bash shell, it is not uncommon to waste time typing the same commands over and over again. This is pretty close to the definition of insanity.

Luckily, bash gives us several ways to avoid repetition and increase productivity.

Today, we will explore the tools we can leverage to optimize what I love to call “shell time”.

Aliases

Bash aliases are one of the methods to define custom or override default commands.

You can consider an alias as a “shortcut” to your desired command with options included.

Many popular Linux distributions come with a set of predefined aliases.

Let’s see the default aliases of Ubuntu 20.04, to do so simply type “alias” and press [ENTER].

Bash Tips and Tricks 1

By simply issuing the command “l”, behind the scenes, bash will execute “ls -CF”.

It's as simple as that.

This is definitely nice, but what if we could specify our own aliases for the most used commands?! The answer is, of course we can!

One of the commands I use extremely often is “cd ..” to change the working directory to the parent folder. I have spent so much time hitting...

This is definitely nice, but what if we could specify our own aliases for the most used commands?! The answer is, of course we can!

One of the commands I use extremely often is “cd ..” to change the working directory to the parent folder. I have spent so much time hitting the same keys…

One day I decided it was enough and I set up an alias!

To create a new alias type “alias ” the alias name, in my case I have chosen “..” followed by “=” and finally the command we want an alias for enclosed in single quotes.

Here is an example below.

Bash Tips and Tricks 2

Functions

Sometimes you will have the need to automate a complex command, perhaps accept arguments as input. Under these constraints, aliases will not be enough to accomplish your goal, but no worries. There is always a way out!

Functions give you the ability to create complex custom commands which can be called directly from the terminal like any other command.

For instance, there are two consecutive actions I do all the time, creating a folder and then cd into it. To avoid the hassle of typing “mkdir newfolder” and then “cd newfolder” i have create a bash function called “mkcd” which takes the name of the folder to be created as argument, create the folder and cd into it.

To declare a new function, we need to type the function name “mkcd ” follower by “()” and our complex command enclosed in curly brackets “{ mkdir -vp "$@" && cd "$@"; }”
