In this article we will demonstrate 16 useful cp command examples specially for the linux beginners. Following is the basic syntax of cp command, Copy a file to another file# cp {options} source_file target_fileCopy File(s) to another directory or folder# cp {options} source_file   target_directory Copy directory to directory# cp {options} source_directory target_directoryLet’s jump into the practical examples of cp command,Example:1) Copy file to target directory Let’s assume we want copy the /etc/passwd file to /mnt/backup directory for some backup purpose, so run below cp command,root@linuxtechi:~# cp /etc/passwd /mnt/backup/ root@linuxtechi:~#Use below command to verify whether it has been copied or not.root@linuxtechi:~# ls...

Combined companies will offer endpoint security with built-in cloud backup. The data backup and storage company Carbonite has announced that it has acquired endpoint security provider Webroot for $618m. The deal will allow Carbonite to combine the strengths of both companies to provide customers with automated cloud security software that has emergency backup already built in.

This tutorial shows you how to list users in Linux. You’ll also learn to list only the logged users. Today different Operating Systems have the capability to use multiple users, each one with their settings and custom configurations to make things easier for administrators and operators to work in together on the same system.Linux on the other hand is very strong on this matter as it allows multiple users to work at the same time on the system in an independent way. It can even allow a single user to open several sessions even from different locations in order to...

As its name suggests, rsync is a synchronization tool. The first time you use it, it simply copies files and directories from one location to another. Subsequent uses, however, synchronize only the differences between these locations. So, if you add one file to the source directory, rsync will copy only the new file to the destination. This saves a lot of time and bandwidth, especially when copying to a remote location.Imagine you have 50GB of data you have to synchronize to a remote server. You can schedule rsync to run daily. Instead of having to copy the whole 50GB...

Expansion Each time you type a command line and press the enter key, bash performs several processes upon the text before it carries out your command. We have seen a couple of cases of how a simple character sequence, for example “*”, can have a lot of meaning to the shell. The process that makes this happen is called expansion. With expansion, you type something and it is expanded into something else before the shell acts upon it. To demonstrate what we mean by this, let's take a look at the echo command. echo is a shell builtin that performs...

A Guided Tour It's time to take our tour. The table below lists some interesting places to explore. This is by no means a complete list, but it should prove to be an interesting adventure. For each of the directories listed below, do the following: cd into each directory. Use ls to list the contents of the directory. If you see an interesting file, use the file command to determine its contents. For text files, use less to view them. Interesting directories and their contents Directory Description / The root directory where the file system begins. In most cases the...

When Linux was originally made public, it lacked many useful applications that the major competitor -Microsoft Windows was successfully supporting. Linux thus created a compatibility layer which was used to run the Windows application on Linux itself called Wine. PlayOnLinux is a front-end UI for the Wine application. It lets you install many popular Windows applications that you otherwise missed to use on Linux. You can run Microsoft Office, Microsoft Internet Explorer, Safari, iTunes and many other applications on your Linux system through PlayOnLinux.In this article, we will explain how to install PlayOnLinux on your Ubuntu both through the command...

Why Bother? Why do you need to learn the command line anyway? Well, let me tell you a story. A few years ago we had a problem where I used to work. There was a shared drive on one of our file servers that kept getting full. I won't mention that this legacy operating system did not support user quotas; that's another story. But the server kept getting full and it stopped people from working. One of our software engineers spent the better part of a day writing a C++ program that would look through all the user's directories and...

Changing operating systems is a big step for anybody -- all the more so because many users are uncertain about exactly what an operating system is.However, switching from Windows to Linux is especially hard. The two operating systems have different assumptions and priorities, as well as different ways of doing things. As a result, it is easy for new Linux users to wind up confused because the expectations they have developed using Windows no longer apply.For instance, here, in no particular order, are seven mistakes that refugees from Windows can fall into when they start to use Linux:7. Choosing the...

Learn a few techniques for avoiding the pipe and making your command-line commands more efficient. Anyone who uses the command line would acknowledge how powerful the pipe is. Because of the pipe, you can take the output from one command and feed it to another command as input. What's more, you can chain one command after another until you have exactly the output you want. Pipes are powerful, but people also tend to overuse them. Although it's not necessarily wrong to do so, and it may not even be less efficient, it does make your commands more complicated. More important...

The linux terminal is not always dull and boring. There are commands to make it do some funny acts to entertain the user. Here is a small collection of such commands.1. Cowsay Install cowsay with apt.$ sudo apt-get install cowsayCowsay is a talking cow that will speak out anything you want it to.$ cowsay "Hi, How are you" _________________ < Hi, How are you > ----------------- \ ^__^ \ (oo)\_______ (__)\ )\/\ ||----w | || ||Don't like cows ? No problem there are other animals in the cow zoo. To find out how many, use the l option to get...

Mirror, mirror, on the wall, which is the best desktop environment of all? While diversity is one of the best features of the Linux community, as users can try various options and find out which one suits the best for them, sometimes it can also create confusions. Especially if you’re new to Linux community, you can easily be overwhelmed by the number of choices you have. When it comes to Desktop Environments, there’s no exception. But trying out each and every desktop environments is a very time-consuming and tiring task.Here, we’ve created a list of the best desktop environments available for Linux distros...

Many of you are Windows 7 users. I get it. Windows 7 just works. But the clock is ticking for Windows 7. In less than a year, Windows 7's free support ends. Come that day, you'll have a choice: You can either run it without being certain you'll get vital security patches (that would be really stupid), or you can pay for Windows 7 Extended Security Updates (ESUs) on a per-device basis, with the price increasing each year. We don't know how much that will be, but I think we can safely assume it won't be cheap. Or, you can...

A simple description of the UNIX system, also applicable to Linux, is this:"On a UNIX system, everything is a file; if something is not a file, it is a process."This statement is true because there are special files that are more than just files (named pipes and sockets, for instance), but to keep things simple, saying that everything is a file is an acceptable generalization. A Linux system, just like UNIX, makes no difference between a file and a directory, since a directory is just a file containing names of other files. Programs, services, texts, images, and so forth, are...

During me being at my parents over the holidays (Christmas 2017) I had the usual IT-support stuff to do, that always happens to tech savvy kids when they are back at home. As I am a happy Linux user for over a decade now, I asked myself if it would be a good idea to switch my parents away from Win 10 to a GNU/Linux (I will call it only Linux during the rest of the post. Sorry Richard ;) ) based system. I did that and now 2 years later I still think it was a good idea: I...

!= If you've been pointed at this page, then the chances are you're a relatively new Linux user who's having some problems making the switch from Windows to Linux. This causes many problems for many people, hence this article was written. Many individual issues arise from this single problem, so the page is broken down into multiple problem areas.Problem #1: Linux isn't exactly the same as Windows. You'd be amazed how many people make this complaint. They come to Linux, expecting to find essentially a free, open-source version of Windows. Quite often, this is what they've been told to...

Myth 1:   Linux is too difficult for ordinary people to use because it uses only text and requires programming. The truth:   Although Linux was originally designed for those with computer expertise, the situation has changed dramatically in the past several years. Today it has a highly intuitive GUI (graphical user interface) similar to those on the Macintosh and Microsoft Windows and it is as easy to use as those operating systems. No knowledge of programming is required. This ease of use is evidenced by the fact that more and more people, including elementary school students and others with...

There are 4 ways of "installing" Linux: "no-install": a "Run-from-CD" LiveCD distribution. Everything runs from the CD and RAM, leaving the hard drive untouched -- completely avoiding the trickiest part of setting up Linux, "hard drive partitioning". After you take out the CD and reboot, everything is restored to the way it was before. (Many of these work just as well with USB flash drive as with CD)Linux on top of Windows: it's possible to keep windows applications running, and run Linux like any other application side-by-side with the Windows applications (this is an advantage compared to dual-booting, which shows...

Weird Linux Display issue Some time back I retired my old Pine64 Media Center. I replaced it with an Intel NUC cube which I'd loaded up with 16GB of RAM and a 1TB hard disk. Soeed isn't really an issue with this system, so I went with spinnign platters rather than an SSD. I installed Linux Mint XFCE4 on it along with all of my music (90GB) and vids of various movies and cartoons I've ripped over the years. Everything is working great, and in fact, today I finally made it all the way through my first complete pass through...

Introduction Welcome to Linux! GNU/Linux is descended from the UNIX operating system, but is open source software, which means that you can view its source code and change it to suit your needs. Of course since this book is geared to those new to Linux, we stay away from very technical issues that are more suited to Linux veterans. This book is going to try to be geared toward the person who has heard about Linux and might be considering trying it out or perhaps the person who has already "taken the plunge" and is looking for more information or...
