In this article, the user will learn the method to generate random positive numbers without duplicate values in Excel. This article briefs learners on two strategies to perform this same task. The first example uses VBA code to generate unique random numbers, while the second example will perform the same task by using the kutool. The main point to understand while performing a task is that a single task can be done in many ways. So, learners should know which one should be used to generate the results accurately and precisely. Example 1: To generate random number in excel ... Read More
Linux is a widely used open-source operating system that offers users the flexibility to execute programs from any location on the system. Unlike other operating systems, Linux does not have fixed program directories, enabling users to access programs from anywhere. This feature is advantageous for users who require a particular program to run from multiple locations. To execute programs from anywhere in Linux, users need to set the PATH environment variable, which contains the locations where Linux searches for executable files. The directories that contain the programs in Linux include /usr/bin, /usr/local/bin, and /sbin. The /usr/bin directory contains most of ... Read More
Introduction If we want to rename any file in Linux, we use “mv” command. But mv command can only rename one file at a time, it can not rename multiple files at one time in terminal. If we want to rename multiples files then we have to use mv command in different way . Also there are other commands available like “rename” , “mmv”, “renameutils” etc. Though some of these commands are not installed default in Linux , we need to install them separately. In this artile, let us understand each command with some example. Approach 1: Using “mv” command ... Read More
Random data can be identified as random values, used to obtain some results. It can be used to perform simulations, to understand the pattern of different system components. It is useful when a user requires a large data set to evaluate some common feature. This article allows the user to generate a random string with three possible methods. The first method is based on the user-defined formula, the second method is based on the use of VBA code, and the final third method is based on the use of kutool. Example 1: To generate random character string in a range ... Read More
Introduction Hidden files in Linux operating system are files that are not displayed when the ls command is executed. A hidden file's name begins with a dot. Not only files, but also directories, can be hidden in Linux. Files in Linux are hidden for a variety of purposes. One of them is to prevent us from accidentally modifying the contents of these files. Another possibility is to avoid these files from being accidentally deleted. Files on shared networks may be hidden for privacy reasons. The majority of hidden files contain environment settings or data that are viewed by applications that ... Read More
Introduction As we increasingly depend on digital media for storing our important files, we tend to accumulate a large number of files over time. It can be challenging to manage these files, particularly when we have multiple copies of the same file that can consume storage space. To solve this issue, Unix provides several methods to find and remove duplicate files, saving us time and disk space. In this article, we will explore various approaches to find duplicate files in Unix and demonstrate the terminal commands that can be used for each method. With these various approaches, we can choose ... Read More
Permutation can be defined as the arrangement of objects in a specific order. In this article, the user would understand the method of generating the permutation by using the VBA code. To do so, the user needs to open the code editor for VBA and after that simply click on the “OK” button. Finally, run the written code, and the permutation sequence will be displayed on the sheet normally. Refer to all the listed steps, to understand the complete method. Example 1: To generate or list all possible permutations in excel by using the VBA code Step 1 To understand ... Read More
This article describes the user with 3 possible ways to generate the possible combination of 3 or more available columns in Excel. The first example is based on using the user-defined formula, to generate the possible combination. The second example is based on the method to use the VBA code, to generate the required combination. While the last example is based on using the Kutool to generate the same data. All three methods are completely accurate and can generate valid and unique results. Example 1: To generate the combination of 3 or multiple columns in Excel by using the formula ... Read More
Among the well-known cloud computing platforms is AWS (Amazon Web Services). Elastic Compute Cloud, or AWS EC2, is a well-known Amazon service. The Amazon CLI (Command Line Interface) is a potent tool that enables users to interact with the EC2 service via the command line in order to effectively administer EC2 instances. In-depth coverage of the Amazon CLI is provided in this article, along with examples of how to carry out various EC2 operations like establishing, listing, initiating, and terminating EC2 instances. The Amazon CLI can be used by users to automate challenging tasks and simplify cloud infrastructure management. Customers ... Read More
Golang, also known as Go, is a popular programming language that is known for its simplicity, efficiency, and performance. Slices are an important data structure in Golang that allows us to work with a sequence of elements of the same type. In this article, we'll discuss how to pass a slice to a function in Golang, and provide a step-by-step guide on how to achieve this task. What is a Slice in Golang? A slice in Golang is a dynamic array, which means it can grow or shrink as needed. It's a powerful data structure that allows us to work ... Read More
