SSH (Secure Shell) is a protocol that allows you to securely transfer files between machines, as well as remotely access and manage them. In this article, we will explore different ways to transfer files over SSH and demonstrate the process with examples and commands. Setting up SSH Before you can transfer files over SSH, you need to set up SSH on both the source and destination machines. SSH is a secure communication protocol that allows you to remotely access and manage your Linux ... Read More
We can add a star rating feature in NextJS by using a library such as react-star-rating. This library allows us to easily display a star rating system and allows for customization of the number of stars and the ability to handle user interactions.Next.js is an open-source web development framework. The Next.js is React Based framework with server side rendering capability. Both speed and SEO are excellent. You can simply build and test sophisticated react-based applications using Next.js. Next.js is written in Typescripts. It offers a Link component that links other components together and has a prefetch property that allows for ... Read More
Introduction On the Linux operating system, the "uniq" command is used to remove duplicate lines from a sorted file. However, sometimes you may need to remove duplicates based on a specific column, rather than the entire row. This becomes particularly useful when working with column-based input files, such as CSV files. In this article, we'll explore several ways to do this per-column "uniq'ing" on Linux. Method 1: Use sort command The sort command is a simple and effective way to sort rows by a specific field and remove duplicates from the sort result. For duplicates, only the first instance will ...

Introduction In this article, we will discuss how to shut down and restart Linux systems from the terminal. The ability to shut down and restart a system from the command line can be useful in a variety of situations, such as when the GUI is unavailable or when automating tasks via Linux shell scripts. Overview Linux is a fairly robust operating system, and as such, rebooting Linux servers is rarely necessary. However, sometimes there are reasons why you need to restart your system. For example, if we are running Linux on our personal computer, restarting and shutting down the system ... Read More
What is a string and a substring? A substring in Go is a portion of a larger string. It is specified by providing a start index and a length, and it contains the characters of the original string starting at the start index and going up to the specified length. The characters in a substring are still a part of the original string and share the same memory. In Go, a string is a sequence of characters. It is an immutable data type, meaning that once a string is created, it cannot be modified. Strings are enclosed in double quotes ... Read More
We can use conditional rendering to only display the spinner when certain conditions are met, such as when data is being fetched from an API. Additionally, we can use CSS to style the spinner and make it match the overall design of our website. What is NextJS? Next.js is a JavaScript framework for building server-rendered React applications. It provides a set of features and tools that make it easy to build and deploy high-performance web applications, such as automatic code splitting, server-side rendering, and static site generation. Next.js also simplifies the setup process and provides a development environment that allows ... Read More
What is String Concatenation? In Go, string concatenation is the process of combining two or more strings into a single string. There are several ways to concatenate strings in Go. We shall discuss them in this article. Method 1: By Using User-Defined Function The function that we create will take two strings as arguments and will return the resultant string by combining both of them as the result. Algorithm Step 1 − First, we need to import the fmt package. Step 2 − Then create a function that will join the two strings together. The function accepts two ... Read More
In the go programming language, there are several types of special escape sequence characters. Usage of each one of them implements a different type of functionality. We shall discuss each one of them one by one in the upcoming examples. Example 1 In this example, we will write a go language program to demonstrate the backlash (//) character. It is used to display a slash in the output of the program. package main import "fmt" func main() { fmt.Println("Program to display a backslash using in the program") } Output Program to display a backslash using in the program\ ...
