海外TECH DEV Community Mastering the awk command in Linux https://dev.to/k1lgor/mastering-the-awk-command-in-linux-5d34 Mastering the awk command in Linux IntroductionHey there As a Linux user you might have heard about the powerful AWK command but you might not be fully familiar with its capabilities AWK is a text processing tool that can help you manipulate data in many ways In this blog post let s dive deep into the AWK command explore its features use cases and some tips to help you master it AWK BasicsAWK is a line oriented programming language that can be used to search and manipulate text files It operates by performing actions on each line of a file based on the patterns specified in the command The basic syntax of the AWK command is as follows awk pattern action filenameThe pattern can be a regular expression or a string and specifies the lines to which the action should be applied The action can be any valid AWK command and is enclosed in braces The filename is the name of the file to be processed Printing ColumnsOne of the most common use cases for AWK is to extract columns from a file The following command will print the first and second columns of a file separated by a comma awk print people txtThe and represent the first and second columns respectively The comma is added to separate the columns Conditional StatementsAWK also supports conditional statements such as if else The following command will print lines from a file that contain the word error awk error print people txtThe pattern error specifies the lines that contain the word error The action print prints those lines CalculationsAWK can be used to perform calculations on data in a file The following command will print the sum of the values in the third column of a file awk sum END print sum people txtThe sum variable is initialized to zero and then incremented by the value of the third column for each line The END keyword specifies that the final action should be performed after all lines have been processed In addition to the basic features of AWK there are many advanced features that can be used to manipulate data in powerful ways Regular ExpressionsAWK supports regular expressions which can be used to search for patterns in text The following command will print lines from a file that start with the word error awk error print error txtThe symbol indicates the start of the line The pattern error specifies lines that start with the word error Field SeparatorsBy default AWK assumes that fields in a file are separated by colon However it is possible to specify a different field separator using the F option The following command will print the first column of a file that is separated by colon awk F print number txtThe F option sets the field separator to colon The represents the first column User Defined FunctionsAWK allows users to define their own functions which can be used to perform custom data processing The following command defines a function called double that multiplies a number by awk function double x return x print double number txtThe function double x takes an argument x and returns x multiplied by The print double action applies the double function to the first column of each line ConclusionIn this blog post we have explored the AWK command in Linux including its basic syntax common use cases and advanced features With this knowledge you can use AWK to manipulate data in a variety of ways Don t forget to experiment with different patterns and actions to fully leverage the power of AWK Good luck Thank you for reading ‍Stay tuned for more ️and logout 2023-03-03 20:38:47

海外TECH DEV Community Learn Context in React in simple steps https://dev.to/uddinarsalan/learn-context-in-react-in-simple-steps-39pc Learn Context in React in simple stepsHey coders in this blog we are going to discuss how to use context in React for passing data between componentsFirst we have to understand how we can share data between different components without using Context we can do it using Props and we are going to learn when to use Props and when to use Context for data state functions etc sharing Suppose we have a simple state in our App jsx file that is responsible for changing the theme either the dark theme or light theme of an App based on when a user clicks on a button that is in the Navbar of our app Now the problem is that our state is in the App jsx and button which changes the state is in Navbar how can we get the data in this case setState in the Navbar to change the theme on user click there are solutions to this problem either we can move the state into Navbar or we can pass it using propsWe can follow the first step also but let us assume that we want to keep the state in the App jsx file onlyFirst let s see the code of the App jsximport React useState from react import Navbar from Navbar import MainSection from MainSection import Footer from Footer const App gt const theme setTheme useState false return lt div style backgroundColor theme fff ffffff gt lt Navbar setTheme setTheme gt lt MainSection gt lt Footer gt lt div gt export default AppIn this App jsx we have set up the state theme using useState and set its default value to false and pass the setTheme function to Navbar using propsNow let s see the Navbar how can we use the passed data in this component to change the theme when the user clicks on the buttonimport React from react const Navbar props gt return lt div gt lt ul gt lt li gt Home lt li gt lt li gt About lt li gt lt li gt Services lt li gt lt ul gt lt button onClick gt props setTheme prevTheme gt prevTheme gt lt button gt lt div gt So this is a simple way of managing state and passing data using propsNow let s see when we can pass data using props and when we should notSuppose there is some state in the App jsx and we want to use it in the first child of the first parent then how can we do it we have to pass data in the form of props to the grandparent and then the parent and then to the child which finally use it But it s not the optimized or a good solution for a more complex React application as the grandparent and parent component are not using the passed data still they are accepting it via props which are rendered each time the state changes this problem of passing props between different components is called props drilling What happens if we have some state in the third grandparent and we want to use it in the child of the first grandparent we cannot pass it using props as they are not hierarchically related to each other in this case what we can do is move the state to App jsx and then pass it using props to the respected components which are not we required every time we used it To solve all these problems React introduced the concept of ContextContext API is a kind of new feature added in version of React that allows one to share state across the entire app or part of it lightly and with ease React context API How it works First we have to create the context using React createContext It returns a consumer and a provider The provider is a component that as its name suggests provides the data to its children Consumer as it so happens is a component that consumes and uses the state Now let us understand how to use it import React createContext from react const UserContext createContext const ContextProvider children gt const theme setTheme useState light function toggleTheme setTheme prevState gt prevState light dark light return lt UserContext Provider value theme toggleTheme gt children lt UserContext Provider gt export ContextProvider UserContext In the above example we first create a context using createContext and then provide the value we need to provide to other components in UserContext Provider and export the Context and ContextProvider componentIt is necessary to wrap the main JSX in vite or App jsx component with ContextProvider so the Context can pass the data or states to other components import React from react import App from App import ReactDOM from react dom import ContextProvider from Context ReactDOM render lt ContextProvider gt lt App gt lt ContextProvider gt document getElementById root Now we can consume the data in any component using the useContext Hookimport React useContext from react import UserContext from Context function Header props const theme toggleTheme useContext UserContext we destructure it to get theme and toggleTheme passed using Context Provider in value return lt header gt lt h gt theme light Light Dark Theme lt h gt lt button onClick toggleTheme gt Set Theme lt button gt lt header gt export default HeaderNow we can pass data using Context from Producer to Consumer even if they are not in hierarchy order and directly from Provider to Consumer this solves the problem of Props drilling and also our data can be managed in only one content normally in the context file This provides a cleaner way of maintaining code and implementing the DRY Don t Repeat Yourself in our code
