MERGING AND SORTING FILES IN LINUX: EASIER THAN YOU THINK

Article | November 24, 2020

There are several reasons to choose Linux over other operating systems such as Windows and macOS. Linux is an open-source, secure, and very lightweight operating system consuming minimal system resources. It also has huge community support and has a ton of distros (variants) to choose from. While we have already posted a bunch of articles on simple file handling methods in Linux, sending email from the terminal, and more, we are going to walk you through the simple yet efficient process of merging and sorting files in Linux. Just like with any other operation in Linux, there are several ways you can sort and merge the files in Linux. Choosing which method to use solely depends on the user and based on what needs to be accomplished. In this article, we will show you some easy yet powerful file sorting and merging methods in Linux while pointing out the differences and importance of each method. Cat Cat is one of the easiest and simple commands in Linux that can combine multiple files into one. All you have to do is list all the files that you wish to merge into a single file along with the new file name you wish to create. If a file with the name of the final output already exists, then it will be overwritten by the one being created. Here is a very simple implementation of cat command. $ cat file1 file2 file3 file4 > Newfile However, if you wish to append information from multiple files into an already existing file, you can use ">>" instead of ">." Below is an example $ cat file1 file2 file3 file4 >> Newfile The cat command can also be used in many ways. It is also one of the most flexible and simple ways of reading the content of the file. To view the content of a file called file1, simply use the below command. $cat file1 Join Join is another command to merge the data of multiple files. While it is as easy and simple as the cat command is, it has a catch. Unlike cat, join cannot just simple combine the data of multiple files. Instead, the command allows users to merge the content of multiple files based on a common field. For instance, consider that two files need to be combined. One file contains names, whereas the other file contains IDs, and the join command can be used to combine both these files in a way that the names and their corresponding IDs appear in the same line. However, users need to make sure that the data in both these files have the common key field with which they will be joined.

However, users need to make sure that the data in both these files have the common key field with which they will be joined. Syntax $join [OPTION] FILE1 FILE2 Example: Assume file1.txt contains ... 1 Aarav 2 Aashi 3 Sukesh And, file2.txt contains ... 1 101 2 102 3 103 The command ... $ join file1.txt file2.txt will result in: 1 Aarav 101 2 Aashi 102 3 Sukesh 103 Note that by default, the join command takes the first column as the key to join multiple files. Also, if you wish to store the final data of the two files joined into another file, you can use this command: $ cat file1.txt file2.txt > result.txt Paste The paste command is used to join multiple files horizontally by performing parallel merging. The command outputs the lines from each file specified, separated by a tab as a delimiter by default to the standard output. Assume there is a file called numbers.txt containing numbers from 1 to 4. And there are another two files called countries.txt and capital.txt containing four countries and their corresponding capitals, respectively. The command below will join the information of these three files and will be separated by a tab space as a delimiter. $ paste numbers.txt countries.txt capital.txt However, you can also specify any delimiter by adding a delimiter option to the above command. For example, if we need the delimited to be "-" you can use this command: $ paste -d “-” numbers.txt countries.txt capital.txt Sort The sort command in Linux, as the name suggests, is used to sort a file as well as arrange the records in a particular order. Sort can also be paired with multiple other Linux commands such as cat by simply joining the two commands using a pipe "|" symbol. For instance, if you wish to merge multiple files, sort them alphabetically and store them in another file, you can use this command: $ cat file1.txt file2.txt file3.txt | sort > finalfile.txt There are several reasons to choose Linux over other operating systems such as Windows and macOS.

There are several other ways of merging and sorting files and data in the Linux operating system. What makes Linux unique is its ability to pair up multiple commands to achieve its purpose. Once users start to make themselves acquainted with these commands, it can save a lot of time and effort while performing tasks with more precision and efficiency.

Noxious Zero-Click Attack: What Is It And How To Avoid It

Article | January 19, 2021

For years, we have been told that cyber-attacks happen due to human-errors. Almost every person has stressed about training to prevent cyber-attacks from taking place. We have always been on the alert to dodge errant clicks or online downloads that might infect devices with security threats. However, not all attacks need a user’s oversight to open the door. Although avoiding clicking on phishing emails is still significant but there is a cyber threat that does not need any human error and has been in the recent news. It is known as Zero-Click attack where some vulnerabilities can be misused by hackers to launch attacks even without interaction from the victim. Rather than depending on the hardware or software flaws to get access to the victim’s device, zero-click attacks eliminate the human error equation. There is nothing a victim can do once coming into the limelight of the hacker. Also, with the flourishing use of smartphones around the world that entails all the personal information and data, this thread has expanded enormously. How Zero-Click Attacks Occur? The core condition for successfully pulling off a zero-click is creating a specially designed piece of data which is then sent to the targeted device over a wireless network connection including mobile internet or wifi. This then hit a scarcely documented vulnerability on the software or hardware level. The vulnerability majorly affects the messaging or emailing apps. The attacks that have begun from Apple’s mail app on iPhone or iPad, have now moved ahead on Whatsapp and Samsung devices. In iOS 13, the vulnerability allowed zero-click when the mail runs in the background. It enables attackers to read, edit, delete, or leak the email inside the app. Later these attacks moved to Samsung’s android devices having version 4.4.4 or above. The successful attacks provide similar access to the hackers as an owner, entailing contacts, SMS, and call logs. In 2019, a breach on Whatsapp used the voice call functionality of the app to ring the victim’s phone. Even if the victim didn’t pick the call and later deleted it, the attacks still installed malicious data packets. These grants access to the hacker to take complete control of call logs, locations, data, camera, and even microphone of the device. Another similar attack had happened due to the frangibility in the chipset of WI-FI that is used in streaming, gaming, smart home devices, and laptops. The zero-click attack blooms on the increase of mobile devices as the number of smartphones have reached above 3 billion. How To Avoid Zero-Click Attacks? Most of the attacks of zero-click target certain victims including corporate executives, government officials, and journalists. But anyone using a smartphone is a possible target. These attacks cannot be spotted due to the lack of vulnerabilities. So the users have to keep the operating system along with the third-party software updated. Also, it is a must to give minimal permissions to apps that are being installed on the device. Moreover, if you own a business and are afraid of the zero-click attacks on your company’s app, you can always seek IT consultations from top-notch companies orhire developersthat will help in developing applications with hard-to-creep-into programming languages where detecting an attack is efficient.

Security News This Week: A Tiny Piece of Tape Tricked Teslas Into Speeding Up 50 MPH

Article | February 22, 2020

This week was filled with wide-scale calamity. Hundreds of millions of PCs have components whose firmware is vulnerable to hacking which is to say, pretty much all of them. It's a problem that's been known about for years, but doesn't seem to get any better. Likewise, Bluetooth implementation mistakes in seven SoC—system on chips—have exposed at least 480 internet-of-things devices to a range of attacks. IoT manufacturers will often outsource components, so a mistake in one SoC can impact a wide range of connected doodads. The most troubling part, though, is that medical devices like pacemakers and blood glucose monitors are among the affected tech. YouTube Gaming, meanwhile, wants to take Twitch's crown as the king of videogame streaming. But its most-viewed channels are almost all scams and cheats, a moderation challenge that it'll have to take more seriously if it wants the legitimacy it's spending big money to attain. In another corner of Alphabet's world, hundreds of Chrome extensions were caught siphoning data from people who installed them, part of a sprawling adware scheme.
