## Basic Web Development Environment Setup
Basic Web Development Environment Setup (CLICK HERE)
#### Windows Subsystem for Linux (WSL) and Ubuntu Test if you have Ubuntu installed by typing "Ubuntu" in the search box in the bottom app bar that reads "Type here to search". If you see a search result that reads **"Ubuntu 20.04 LTS"** with "App" under it, then you have it installed. ``` 1. In the application search box in the bottom bar, type "PowerShell" to find the application named "Windows PowerShell" 2. Right-click on "Windows PowerShell" and choose "Run as administrator" from the popup menu 3. In the blue PowerShell window, type the following: `Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux` 4. Restart your computer 5. In the application search box in the bottom bar, type "Store" to find the application named "Microsoft Store" 6. Click "Microsoft Store" 7. Click the "Search" button in the upper-right corner of the window 8. Type in "Ubuntu" 9. Click "Run Linux on Windows (Get the apps)" 10. Click the orange tile labeled **"Ubuntu"** Note that there are 3 versions in the Microsoft Store… you want the one just entitled 'Ubuntu' 11. Click "Install" 12. After it downloads, click "Launch" 13. If you get the option, pin the application to the task bar. Otherwise, right-click on the orange Ubuntu icon in the task bar and choose "Pin to taskbar" 14. When prompted to "Enter new UNIX username", type your first name with no spaces 15. When prompted, enter and retype a password for this UNIX user (it can be the same as your Windows password) 16. Confirm your installation by typing the command `whoami 'as in who-am-i'`followed by Enter at the prompt (it should print your first name) 17. You need to update your packages, so type `sudo apt update` (if prompted for your password, enter it) 18. You need to upgrade your packages, so type `sudo apt upgrade` (if prompted for your password, enter it) ``` ### Git Git comes with Ubuntu, so there's nothing to install. However, you should configure it using the following instructions. Open an Ubuntu terminal if you don't have one open already. 1. > You need to configure Git, so type `git config --global user.name "Your Name"` with replacing "Your Name" with your real name. 2. > You need to configure Git, so type `git config --global user.email your@email.com` with replacing "your@email.com" with your real email. **Note: if you want git to remember your login credentials type:** git config --global credential.helper store ### Google Chrome Test if you have Chrome installed by typing "Chrome" in the search box in the bottom app bar that reads "Type here to search". If you see a search result that reads "Chrome" with "App" under it, then you have it installed. Otherwise, follow these instructions to install Google Chrome. ### Node.js Test if you have Node.js installed by opening an Ubuntu terminal and typing `node --version`. If it reports "Command 'node' not found", then you need to follow these directions. 1. > In the Ubuntu terminal, type `sudo apt update` and press Enter 2. > In the Ubuntu terminal, type `sudo apt install build-essential` and press Enter 3. > In the Ubuntu terminal, type `curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.2/install.sh | bash` and press Enter 4. > In the Ubuntu terminal, type `../.bashrc` and press Enter 5. > In the Ubuntu terminal, type `nvm install --lts` and press Enter 6. > Confirm that **node** is installed by typing `node --version` and seeing it print something that is not "Command not found"! ### Unzip You will often have to download a zip file and unzip it. It is easier to do this from the command line. So we need to install a linux unzip utility. In the Ubuntu terminal type: `sudo apt install unzip` and press Enter Mocha.js Test if you have Mocha.js installed by opening an Ubuntu terminal and typing `which mocha`. If it prints a path, then you're good. Otherwise, if it prints nothing, install Mocha.js by typing `npm install -g mocha`. ### Python 3 Ubuntu does not come with Python 3. Install it using the command `sudo apt install python3`. Test it by typing `python3 --version` and seeing it print a number. ### Note about WSL As of the time of writing of this document, WSL has an issue renaming or deleting files if Visual Studio Code is open. So before doing any linux commands which manipulate files, make sure you **close** Visual Studio Code before running those commands in the Ubuntu terminal. ### Some other common instillations ```bash # Installing build essentials sudo apt-get install -y build-essential libssl-dev # Nodejs and NVM curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.2/install.sh | bash source ~/.profile sudo nvm install 7.10.0 sudo nvm use 7.10.0 node -v #nodemon sudo npm install -g nodemon sudo npm install -g loopback-cli # Forever to run nodejs scripts forever sudo npm install forever -g # Git - a version control system sudo apt-get update sudo apt-get install -y git xclip # Grunt - an automated task runner sudo npm install -g grunt-cli # Bower - a dependency manager sudo npm install -g bower # Yeoman - for generators sudo npm install -g yo # maven sudo apt-get install maven -y # Gulp - an automated task runner sudo npm install -g gulp-cli # Angular FullStack - My favorite MEAN boilerplate (MEAN = MongoDB, Express, Angularjs, Nodejs) sudo npm install -g generator-angular-fullstack # Vim, Curl, Python - Some random useful stuff sudo apt-get install -y vim curl python-software-properties sudo apt-get install -y python-dev, python-pip sudo apt-get install -y libkrb5-dev # Installing JDK and JRE sudo apt-get install -y default-jre sudo apt-get install -y default-jdk # Archive Extractors sudo apt-get install -y unace unrar zip unzip p7zip-full p7zip-rar sharutils rar uudeview mpack arj cabextract file-roller # FileZilla - a FTP client sudo apt-get install -y filezilla ```

Remove duplicate lines from a text file ### Description > Notes: > //...syntax of uniq...// > $uniq [OPTION] [INPUT[OUTPUT]] > The syntax of this is quite easy to understand. Here, INPUT refers to the input file in which repeated lines need to be filtered out and if INPUT isn't specified then uniq reads from the standard input. OUTPUT refers to the output file in which you can store the filtered output generated by uniq command and as in case of INPUT if OUTPUT isn't specified then uniq writes to the standard output. Now, let's understand the use of this with the help of an example. Suppose you have a text file named kt.txt which contains repeated lines that needs to be omitted. This can simply be done with uniq. ###### code ```bash sudo apt install uniq uniq -u input.txt output.txt ``` --- ## 21.

OVERWRITE LOCAL CHANGES ### Description Important: If you have any local changes, they will be lost. With or without --hard option, any local commits that haven't been pushed will be lost.[*] If you have any files that are not tracked by Git (e.g. uploaded user content), these files will not be affected. > Notes: > First, run a fetch to update all origin/ refs to latest: ###### code ```bash git fetch --all ## Backup your current branch: git branch backup-master ## Then, you have two options: git reset --hard origin/master ## OR If you are on some other branch: git reset --hard origin/ ## Explanation: ## git fetch downloads the latest from remote without trying to merge or rebase anything. ## Then the git reset resets the master branch to what you just fetched. The --hard option changes all the files in your working tree to match the files in origin/master git fetch --all git reset --hard origin/master ``` --- ## 28.

↞↠ Getting Started With GatsbyJS ↞↠
# --- ## 🚀 Quick start 1. **Create a Gatsby site.** Use the Gatsby CLI to create a new site, specifying the default starter. ```bashell # create a new Gatsby site using the default starter gatsby new my-default-starter https://github.com/gatsbyjs/gatsby-starter-default ``` 1. **Start developing.** Navigate into your new site's directory and start it up. ```bashell cd my-default-starter/ gatsby develop ``` 1. **Open the source code and start editing!** Your site is now running at `http://localhost:8000`! _Note: You'll also see a second link:_`http://localhost:8000/___graphql`_. This is a tool you can use to experiment with querying your data. Learn more about using this tool in the [Gatsby tutorial](https://www.gatsbyjs.com/tutorial/part-five/#introducing-graphiql)._ Open the `my-default-starter` directory in your code editor of choice and edit `src/pages/index.js`. Save your changes and the browser will update in real time! ## 🧐 What's inside? A quick look at the top-level files and directories you'll see in a Gatsby project. . ├── node_modules ├── src ├── .gitignore ├── .prettierrc ├── gatsby-browser.js ├── gatsby-config.js ├── gatsby-node.js ├── gatsby-ssr.js ├── LICENSE ├── package-lock.json ├── package.json └── README.md 1. **`/node_modules`**: This directory contains all of the modules of code that your project depends on (npm packages) are automatically installed. 2. **`/src`**: This directory will contain all of the code related to what you will see on the front-end of your site (what you see in the browser) such as your site header or a page template. `src` is a convention for "source code". 3. **`.gitignore`**: This file tells git which files it should not track / not maintain a version history for. 4. **`.prettierrc`**: This is a configuration file for [Prettier](https://prettier.io/).

Full documentation for Gatsby lives [on the website](https://www.gatsbyjs.com/). Here are some places to start: - **For most developers, we recommend starting with our [in-depth tutorial for creating a site with Gatsby**](https://www.gatsbyjs.com/tutorial/).\*\* It starts with zero assumptions about your level of ability and walks through every step of the process. - - **To dive straight into code samples, head [to our documentation**](https://www.gatsbyjs.com/docs/).\*\* In particular, check out the *Guides*, *API Reference*, and *Advanced Tutorials\* sections in the sidebar. --- ### Gatsby With Netlify CMS This tutorial will use [gatsby-personal-starter-blog](https://github.com/thomaswang/gatsby-personal-starter-blog), a Gatsby starter based on the official [gatsby-starter-blog](/starters/gatsbyjs/gatsby-starter-blog/). The differences are that `gatsby-personal-starter-blog` is configured to run the blog on a subdirectory, `/blog`, and comes pre-installed with [Netlify CMS](https://www.netlifycms.org/) for content editing. It also adds VS Code highlighting for code blocks. ## Prerequisites - A GitHub account - The [Gatsby CLI](/docs/reference/gatsby-cli/) installed ## Set up a Netlify CMS-managed Gatsby site in 5 steps ### Step 1 Open your Terminal and run the following command from the Gatsby CLI to create a new Gatsby site using [gatsby-personal-starter-blog](https://github.com/thomaswang/gatsby-personal-starter-blog). ```shell gatsby new [your-project-name] https://github.com/thomaswangio/gatsby-personal-starter-blog ``` ### Step 2 Once the Gatsby site is finished installing all the packages and dependencies, you can now go into the directory and run the site locally. ```shell cd [your-project-name] gatsby develop ``` Now you can go to `http://localhost:8000` to see your new site, but what's extra cool is that Netlify CMS is pre-installed and you can access it at `http://localhost:8000/admin` A CMS, or content management system, is useful because you can add content like blog posts from a dashboard on your site, instead of having to add posts manually with Markdown. However, you'll likely want to be able to access the CMS from a deployed website, not just locally. For that, you'll need to deploy to Netlify through GitHub, set up continuous deployment, and do a few configurations. You'll go over this in [Step-5](#step-5). ### Step 3 Open the project in your code editor and open `static/admin/config.yml`. Replace `your-username/your-repo-name` with your GitHub username and project name. This step is important for managing and deploying the Netlify CMS interface. ```diff backend: - name: test-repo + name: github + repo: your-username/your-repo-name ``` #### Customizing your site Head into `gatsby-config.js` and you can edit your siteMetadata, add a Google Analytics tracking ID, and your app icon/favicon. Test out the edits for the deployed build by quitting the development server and running `gatsby build && gatsby serve`. You'll likely also want to edit the `README.md` and `package.json` files to include your own project details. ### Step 4 Open [github.com](https://github.com) and create a new repository, with the same name as your project. Push your new Gatsby site's code to GitHub using the following Terminal commands: ```shell git init git add . git commit -m "initial commit" git remote add origin https://github.com/[your-username]/[your-repo-name].git git push -u origin master ``` Then, open [app.netlify.com](https://app.netlify.com) and add a "New site from Git". Choose your newly created repo and click on "Deploy site" with the default deployment settings. > _Note: if you don't see the correct repo listed, you may need to install or reconfigure the Netlify app on GitHub._ ![Netlify Dashboard for Creating a new site](netlify-dashboard.png) ### Step 5 To make sure that Netlify CMS has access to your GitHub repo, you need to set up an OAuth application on GitHub. The instructions for that are here: [Netlify's Using an Authorization Provider](https://www.netlify.com/docs/authentication-providers/#using-an-authentication-provider). For the "Homepage URL" – you can use your Netlify subdomain, `[name-of-your-site].netlify.com`, or you can use a custom domain. To customize the subdomain, look for the "Edit site name" field under "Domain Management" for your project on the [Netlify app](https://app.netlify.com). To connect your Netlify site to your custom domain instead, see [Netlify’s instructions on custom domains](https://www.netlify.com/docs/custom-domains/). Once you've configured an authentication provider then you'll be able to use Netlify CMS at your deployed site to add new posts. ![Netlify and GitHub Authorization](https://cdn.netlify.com/67edd5b656c432888d736cd40125cb61376905bb/c1cba/img/docs/github-oauth-config.png) Copy the credentials of your new app listed on [GitHub OAuth Apps](https://github.com/settings/developers) and install a new auth provider on Netlify using them. ![Setting up access control](netlify-install-oauth-provider.png) #### Benefits of Netlify CMS, GitHub, and Netlify Workflow Congrats! Now that Netlify CMS is successfully configured to your project, every time you add a new post, the content will be stored in your repository and versioned on GitHub because Netlify CMS is Git-based. Also, thanks to [Netlify's Continuous Deployment](https://www.netlify.com/docs/continuous-deployment/), a new version will be deployed every time you add or edit a post. ## You can learn more about Netlify CMS and how to configure it further in the [Netlify CMS documentation](https://www.netlifycms.org/docs/intro/) --- ## Gatsby Project Structure | Gatsby > ## Excerpt > > Inside a Gatsby project, you may see some or all of the following folders and files: Folders /.cache Automatically generated.

[Gatsby's approach to layouts](https://www.gatsbyjs.com/docs/how-to/routing/layout-components/#gatsbys-approach-to-layouts) Gatsby does not, by default, automatically apply layouts to pages (there are, however, ways to do so which will be covered in a later section). Instead, Gatsby follows React's compositional model of importing and using components. This makes it possible to create multiple levels of layouts, e.g. a global header and footer, and then on some pages, a sidebar menu. It also makes it possible to pass data between layout and page components. [What are layout components?](https://www.gatsbyjs.com/docs/how-to/routing/layout-components/#what-are-layout-components) Layout components are for sections of your site that you want to share across multiple pages. For example, Gatsby sites will commonly have a layout component with a shared header and footer. Other common things to add to layouts are a sidebar and/or navigation menu. On this page for example, the header at the top is part of gatsbyjs.com's layout component. [How to create layout components](https://www.gatsbyjs.com/docs/how-to/routing/layout-components/#how-to-create-layout-components) It is recommended to create your layout components alongside the rest of your components (e.g. into `src/components/`). Here is an example of a very basic layout component at `src/components/layout.js`: ``` import React from "react"export default function Layout({ children }) { return (
{children}
)} ``` [](https://www.gatsbyjs.com/docs/how-to/routing/layout-components/#how-to-import-and-add-layout-components-to-pages)How to import and add layout components to pages If you want to apply a layout to a page, you will need to include the `Layout` component and wrap your page in it. For example, here is how you would apply your layout to the front page: ``` import React from "react"import Layout from "../components/layout"export default function Home() { return (

I'm in a layout!

);} ``` Repeat for every page and template that needs this layout. [How to prevent layout components from unmounting](https://www.gatsbyjs.com/docs/how-to/routing/layout-components/#how-to-prevent-layout-components-from-unmounting) As mentioned earlier, Gatsby does not, by default, automatically wrap pages in a layout component. The "top level" component is the page itself. As a result, when the "top level" component changes between pages, React will re-render all children. This means that shared components like navigations will unmount and remount. This will break CSS transitions or React state within those shared components. If you need to set a wrapper component around page components that won't get unmounted on page changes, use the **`wrapPageElement`** [browser API](https://www.gatsbyjs.com/docs/reference/config-files/gatsby-browser/#wrapPageElement) and the [SSR equivalent](https://www.gatsbyjs.com/docs/reference/config-files/gatsby-ssr/#wrapPageElement). Alternatively, you can prevent your layout component from unmounting by using [gatsby-plugin-layout](https://www.gatsbyjs.com/plugins/gatsby-plugin-layout/), which implements the `wrapPageElement` APIs for you. ## Adding Markdown Pages | Gatsby > ## Excerpt > > Gatsby can use Markdown files to create pages in your site. > You add plugins to read and understand folders with Markdown files and from them… --- Gatsby can use Markdown files to create pages in your site. You add plugins to read and understand folders with Markdown files and from them create pages automatically. Here are the steps Gatsby follows for making this happen. 1. Read files into Gatsby from the filesystem 2. Transform Markdown to HTML and [frontmatter](https://www.gatsbyjs.com/docs/how-to/routing/adding-markdown-pages/#frontmatter-for-metadata-in-markdown-files) to data 3. Add a Markdown file 4. Create a Collection Route component for the Markdown files [](https://www.gatsbyjs.com/docs/how-to/routing/adding-markdown-pages/#read-files-into-gatsby-from-the-filesystem)Read files into Gatsby from the filesystem Use the plugin [`gatsby-source-filesystem`](https://www.gatsbyjs.com/plugins/gatsby-source-filesystem/#gatsby-source-filesystem) to read files. [](https://www.gatsbyjs.com/docs/how-to/routing/adding-markdown-pages/#install)Install `npm install gatsby-source-filesystem` [Add Plugin](https://www.gatsbyjs.com/docs/how-to/routing/adding-markdown-pages/#add-plugin)Add plugin Open `gatsby-config.js` to add the `gatsby-source-filesystem` plugin. The `path` option is how you set the directory to search for files. ``` module.exports = { siteMetadata: { title: "My Gatsby Site", }, plugins: [ { resolve: `gatsby-source-filesystem`, options: { name: `markdown-pages`, path: `${__dirname}/src/markdown-pages`, }, }, ],} ``` Completing the above step means that you've "sourced" the Markdown files from the filesystem. You can now "transform" the Markdown to HTML and the YAML frontmatter to JSON. [Transform Markdown to HTML and frontmatter to data using `gatsby-transformer-remark`](https://www.gatsbyjs.com/docs/how-to/routing/adding-markdown-pages/#transform-markdown-to-html-and-frontmatter-to-data-using-gatsby-transformer-remark) You'll use the plugin [`gatsby-transformer-remark`](https://www.gatsbyjs.com/plugins/gatsby-transformer-remark/) to recognize files which are Markdown and read their content. The plugin will convert the frontmatter metadata part of your Markdown files as `frontmatter` and the content part as HTML. [Install transformer plugin](https://www.gatsbyjs.com/docs/how-to/routing/adding-markdown-pages/#install-transformer-plugin) `npm install gatsby-transformer-remark` [Configure plugin](https://www.gatsbyjs.com/docs/how-to/routing/adding-markdown-pages/#configure-plugin) Add this to `gatsby-config.js` after the previously added `gatsby-source-filesystem`. ``` module.exports = { siteMetadata: { title: "My Gatsby Site", }, plugins: [ { resolve: `gatsby-source-filesystem`, options: { name: `markdown-pages`, path: `${__dirname}/src/markdown-pages`, }, }, `gatsby-transformer-remark`, ], } ``` [Add a Markdown file](https://www.gatsbyjs.com/docs/how-to/routing/adding-markdown-pages/#add-a-markdown-file) Create a folder in the `/src` directory of your Gatsby application called `markdown-pages`. Now create a Markdown file inside it with the name `post-1.md`. [Frontmatter for metadata in Markdown files](https://www.gatsbyjs.com/docs/how-to/routing/adding-markdown-pages/#frontmatter-for-metadata-in-markdown-files) When you create a Markdown file, you can include a set of key/value pairs that can be used to provide additional data relevant to specific pages in the GraphQL data layer. This data is called "frontmatter" and is denoted by the triple dashes at the start and end of the block. This block will be parsed by `gatsby-transformer-remark` as YAML. You can then query the data through the GraphQL API from your React components. src/markdown-pages/post-1.md ``` ---slug: "/blog/my-first-post"date: "2019-05-04"title: "My first blog post"--- ``` What is important in this step is the key pair `slug`. The value that is assigned to the key `slug` is used in order to navigate to your post. [](https://www.gatsbyjs.com/docs/how-to/routing/adding-markdown-pages/#create-a-collection-route-for-the-markdown-files)Create a Collection Route for the Markdown files Create `src/pages/{MarkdownRemark.frontmatter__slug}.js` and add the following code: src/pages/{MarkdownRemark.frontmatter\_\_slug}.js ``` import React from "react" import { graphql } from "gatsby"export default function Template({ data, }) { const { markdownRemark } = data const { frontmatter, html } = markdownRemark return (

{frontmatter.title}

{frontmatter.date}

)}export const pageQuery = graphql` query($id: String!) { markdownRemark(id: { eq: $id }) { html frontmatter { date(formatString: "MMMM DD, YYYY") slug title } } }` ``` Two things are important in the file above: 1. A GraphQL query is made in the second half of the file to get the Markdown data. Gatsby has automagically given you all the Markdown metadata and HTML in this query's result. **Note: To learn more about GraphQL, consider this [excellent resource](https://www.howtographql.com/)** 2. The result of the query is injected by Gatsby into the component as the `data` prop. `props.data.markdownRemark` is the property that has all the details of the Markdown file. Next you could create a page component at `src/pages/blog/index.js` to serve as a listing page for all your blog posts. This should get you started on some basic Markdown functionality in your Gatsby site. You can further customize the frontmatter and the component file to get desired effects! For more information, have a look in the working example `using-markdown-pages`. You can find it in the [Gatsby examples section](https://github.com/gatsbyjs/gatsby/tree/master/examples).

--- ### Overview The **`_.get()` method** in Lodash retrieves the object’s value at a specific path. If the value is not present at the object’s specific path, it will be resolved as `undefined`. This method will return the default value if specified in such a case. ### Syntax ```js _.get(object, path, defaultValue); ``` ### Parameters This method accepts the following parameters: - **`object`**: The object in which the given path will be queried. - **`path`**: The path used to retrieve the value from the object. - **`defaultValue`**: The default value that will be returned for resolved values that are undefined. ### Return value This method will return the value at the specified path if found. Otherwise, it will return the default value if specified. ### Example Let’s look at an example of the `_.get()` method in the code snippet below: ### Explanation In the HTML tab: - **Line 5**: We import the `lodash` script. In the JavaScript tab: - **Lines 2 to 15**: We create an object to perform a query. - **Line 18**: We define a variable `collegeYopPath` to get the value. - **Lines 19**: We use the `_.get()` method and pass the `object`, `collegeYopPath`, and a default value as parameters. - **Line 22**: We define a variable `falsyPath` to get the value. - **Lines 23**: We use the `_.get()` method and pass the `object`, `falsyPath` and a `default value` as parameters. ### Output - The `_.get()` method at **line 19** contains a valid path, and therefore the expression is resolved, and `2021` is printed on the console. - The `_.get()` method at **Line 23** contains an invalid path, and therefore the expression is resolved as `undefined`. ``` module.exports = { siteMetadata: { title: "My Gatsby Site", }, plugins: [ { resolve: `gatsby-source-filesystem`, options: { name: `markdown-pages`, path: `${__dirname}/src/markdown-pages`, }, }, ],} ``` Completing the above step means that you've "sourced" the Markdown files from the filesystem.

## Basic Web Development Environment Setup
Basic Web Development Environment Setup (CLICK HERE)
#### Windows Subsystem for Linux (WSL) and Ubuntu Test if you have Ubuntu installed by typing "Ubuntu" in the search box in the bottom app bar that reads "Type here to search". If you see a search result that reads **"Ubuntu 20.04 LTS"** with "App" under it, then you have it installed. ``` 1. In the application search box in the bottom bar, type "PowerShell" to find the application named "Windows PowerShell" 2. Right-click on "Windows PowerShell" and choose "Run as administrator" from the popup menu 3. In the blue PowerShell window, type the following: `Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux` 4. Restart your computer 5. In the application search box in the bottom bar, type "Store" to find the application named "Microsoft Store" 6. Click "Microsoft Store" 7. Click the "Search" button in the upper-right corner of the window 8. Type in "Ubuntu" 9. Click "Run Linux on Windows (Get the apps)" 10. Click the orange tile labeled **"Ubuntu"** Note that there are 3 versions in the Microsoft Store… you want the one just entitled 'Ubuntu' 11. Click "Install" 12. After it downloads, click "Launch" 13. If you get the option, pin the application to the task bar. Otherwise, right-click on the orange Ubuntu icon in the task bar and choose "Pin to taskbar" 14. When prompted to "Enter new UNIX username", type your first name with no spaces 15. When prompted, enter and retype a password for this UNIX user (it can be the same as your Windows password) 16. Confirm your installation by typing the command `whoami 'as in who-am-i'`followed by Enter at the prompt (it should print your first name) 17. You need to update your packages, so type `sudo apt update` (if prompted for your password, enter it) 18. You need to upgrade your packages, so type `sudo apt upgrade` (if prompted for your password, enter it) ``` ### Git Git comes with Ubuntu, so there's nothing to install. However, you should configure it using the following instructions. Open an Ubuntu terminal if you don't have one open already. 1. > You need to configure Git, so type `git config --global user.name "Your Name"` with replacing "Your Name" with your real name. 2. > You need to configure Git, so type `git config --global user.email your@email.com` with replacing "your@email.com" with your real email. **Note: if you want git to remember your login credentials type:** git config --global credential.helper store ### Google Chrome Test if you have Chrome installed by typing "Chrome" in the search box in the bottom app bar that reads "Type here to search". If you see a search result that reads "Chrome" with "App" under it, then you have it installed. Otherwise, follow these instructions to install Google Chrome. ### Node.js Test if you have Node.js installed by opening an Ubuntu terminal and typing `node --version`. If it reports "Command 'node' not found", then you need to follow these directions. 1. > In the Ubuntu terminal, type `sudo apt update` and press Enter 2. > In the Ubuntu terminal, type `sudo apt install build-essential` and press Enter 3. > In the Ubuntu terminal, type `curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.2/install.sh | bash` and press Enter 4. > In the Ubuntu terminal, type `../.bashrc` and press Enter 5. > In the Ubuntu terminal, type `nvm install --lts` and press Enter 6. > Confirm that **node** is installed by typing `node --version` and seeing it print something that is not "Command not found"! ### Unzip You will often have to download a zip file and unzip it. It is easier to do this from the command line. So we need to install a linux unzip utility. In the Ubuntu terminal type: `sudo apt install unzip` and press Enter Mocha.js Test if you have Mocha.js installed by opening an Ubuntu terminal and typing `which mocha`. If it prints a path, then you're good. Otherwise, if it prints nothing, install Mocha.js by typing `npm install -g mocha`. ### Python 3 Ubuntu does not come with Python 3. Install it using the command `sudo apt install python3`. Test it by typing `python3 --version` and seeing it print a number. ### Note about WSL As of the time of writing of this document, WSL has an issue renaming or deleting files if Visual Studio Code is open. So before doing any linux commands which manipulate files, make sure you **close** Visual Studio Code before running those commands in the Ubuntu terminal. ### Some other common instillations ```bash # Installing build essentials sudo apt-get install -y build-essential libssl-dev # Nodejs and NVM curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.2/install.sh | bash source ~/.profile sudo nvm install 7.10.0 sudo nvm use 7.10.0 node -v #nodemon sudo npm install -g nodemon sudo npm install -g loopback-cli # Forever to run nodejs scripts forever sudo npm install forever -g # Git - a version control system sudo apt-get update sudo apt-get install -y git xclip # Grunt - an automated task runner sudo npm install -g grunt-cli # Bower - a dependency manager sudo npm install -g bower # Yeoman - for generators sudo npm install -g yo # maven sudo apt-get install maven -y # Gulp - an automated task runner sudo npm install -g gulp-cli # Angular FullStack - My favorite MEAN boilerplate (MEAN = MongoDB, Express, Angularjs, Nodejs) sudo npm install -g generator-angular-fullstack # Vim, Curl, Python - Some random useful stuff sudo apt-get install -y vim curl python-software-properties sudo apt-get install -y python-dev, python-pip sudo apt-get install -y libkrb5-dev # Installing JDK and JRE sudo apt-get install -y default-jre sudo apt-get install -y default-jdk # Archive Extractors sudo apt-get install -y unace unrar zip unzip p7zip-full p7zip-rar sharutils rar uudeview mpack arj cabextract file-roller # FileZilla - a FTP client sudo apt-get install -y filezilla ```

Remove duplicate lines from a text file ### Description > Notes: > //...syntax of uniq...// > $uniq [OPTION] [INPUT[OUTPUT]] > The syntax of this is quite easy to understand. Here, INPUT refers to the input file in which repeated lines need to be filtered out and if INPUT isn't specified then uniq reads from the standard input. OUTPUT refers to the output file in which you can store the filtered output generated by uniq command and as in case of INPUT if OUTPUT isn't specified then uniq writes to the standard output. Now, let's understand the use of this with the help of an example. Suppose you have a text file named kt.txt which contains repeated lines that needs to be omitted. This can simply be done with uniq. ###### code ```bash sudo apt install uniq uniq -u input.txt output.txt ``` --- ## 21.

OVERWRITE LOCAL CHANGES ### Description Important: If you have any local changes, they will be lost. With or without --hard option, any local commits that haven't been pushed will be lost.[*] If you have any files that are not tracked by Git (e.g. uploaded user content), these files will not be affected. > Notes: > First, run a fetch to update all origin/ refs to latest: ###### code ```bash git fetch --all ## Backup your current branch: git branch backup-master ## Then, you have two options: git reset --hard origin/master ## OR If you are on some other branch: git reset --hard origin/ ## Explanation: ## git fetch downloads the latest from remote without trying to merge or rebase anything. ## Then the git reset resets the master branch to what you just fetched. The --hard option changes all the files in your working tree to match the files in origin/master git fetch --all git reset --hard origin/master ``` --- ## 28.

## Basic Web Development Environment Setup
Basic Web Development Environment Setup (CLICK HERE)
#### Windows Subsystem for Linux (WSL) and Ubuntu Test if you have Ubuntu installed by typing "Ubuntu" in the search box in the bottom app bar that reads "Type here to search". If you see a search result that reads **"Ubuntu 20.04 LTS"** with "App" under it, then you have it installed. ``` 1. In the application search box in the bottom bar, type "PowerShell" to find the application named "Windows PowerShell" 2. Right-click on "Windows PowerShell" and choose "Run as administrator" from the popup menu 3. In the blue PowerShell window, type the following: `Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux` 4. Restart your computer 5. In the application search box in the bottom bar, type "Store" to find the application named "Microsoft Store" 6. Click "Microsoft Store" 7. Click the "Search" button in the upper-right corner of the window 8. Type in "Ubuntu" 9. Click "Run Linux on Windows (Get the apps)" 10. Click the orange tile labeled **"Ubuntu"** Note that there are 3 versions in the Microsoft Store… you want the one just entitled 'Ubuntu' 11. Click "Install" 12. After it downloads, click "Launch" 13. If you get the option, pin the application to the task bar. Otherwise, right-click on the orange Ubuntu icon in the task bar and choose "Pin to taskbar" 14. When prompted to "Enter new UNIX username", type your first name with no spaces 15. When prompted, enter and retype a password for this UNIX user (it can be the same as your Windows password) 16. Confirm your installation by typing the command `whoami 'as in who-am-i'`followed by Enter at the prompt (it should print your first name) 17. You need to update your packages, so type `sudo apt update` (if prompted for your password, enter it) 18. You need to upgrade your packages, so type `sudo apt upgrade` (if prompted for your password, enter it) ``` ### Git Git comes with Ubuntu, so there's nothing to install. However, you should configure it using the following instructions. Open an Ubuntu terminal if you don't have one open already. 1. > You need to configure Git, so type `git config --global user.name "Your Name"` with replacing "Your Name" with your real name. 2. > You need to configure Git, so type `git config --global user.email your@email.com` with replacing "your@email.com" with your real email. **Note: if you want git to remember your login credentials type:** git config --global credential.helper store ### Google Chrome Test if you have Chrome installed by typing "Chrome" in the search box in the bottom app bar that reads "Type here to search". If you see a search result that reads "Chrome" with "App" under it, then you have it installed. Otherwise, follow these instructions to install Google Chrome. ### Node.js Test if you have Node.js installed by opening an Ubuntu terminal and typing `node --version`. If it reports "Command 'node' not found", then you need to follow these directions. 1. > In the Ubuntu terminal, type `sudo apt update` and press Enter 2. > In the Ubuntu terminal, type `sudo apt install build-essential` and press Enter 3. > In the Ubuntu terminal, type `curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.2/install.sh | bash` and press Enter 4. > In the Ubuntu terminal, type `../.bashrc` and press Enter 5. > In the Ubuntu terminal, type `nvm install --lts` and press Enter 6. > Confirm that **node** is installed by typing `node --version` and seeing it print something that is not "Command not found"! ### Unzip You will often have to download a zip file and unzip it. It is easier to do this from the command line. So we need to install a linux unzip utility. In the Ubuntu terminal type: `sudo apt install unzip` and press Enter Mocha.js Test if you have Mocha.js installed by opening an Ubuntu terminal and typing `which mocha`. If it prints a path, then you're good. Otherwise, if it prints nothing, install Mocha.js by typing `npm install -g mocha`. ### Python 3 Ubuntu does not come with Python 3. Install it using the command `sudo apt install python3`. Test it by typing `python3 --version` and seeing it print a number. ### Note about WSL As of the time of writing of this document, WSL has an issue renaming or deleting files if Visual Studio Code is open. So before doing any linux commands which manipulate files, make sure you **close** Visual Studio Code before running those commands in the Ubuntu terminal. ### Some other common instillations ```bash # Installing build essentials sudo apt-get install -y build-essential libssl-dev # Nodejs and NVM curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.2/install.sh | bash source ~/.profile sudo nvm install 7.10.0 sudo nvm use 7.10.0 node -v #nodemon sudo npm install -g nodemon sudo npm install -g loopback-cli # Forever to run nodejs scripts forever sudo npm install forever -g # Git - a version control system sudo apt-get update sudo apt-get install -y git xclip # Grunt - an automated task runner sudo npm install -g grunt-cli # Bower - a dependency manager sudo npm install -g bower # Yeoman - for generators sudo npm install -g yo # maven sudo apt-get install maven -y # Gulp - an automated task runner sudo npm install -g gulp-cli # Angular FullStack - My favorite MEAN boilerplate (MEAN = MongoDB, Express, Angularjs, Nodejs) sudo npm install -g generator-angular-fullstack # Vim, Curl, Python - Some random useful stuff sudo apt-get install -y vim curl python-software-properties sudo apt-get install -y python-dev, python-pip sudo apt-get install -y libkrb5-dev # Installing JDK and JRE sudo apt-get install -y default-jre sudo apt-get install -y default-jdk # Archive Extractors sudo apt-get install -y unace unrar zip unzip p7zip-full p7zip-rar sharutils rar uudeview mpack arj cabextract file-roller # FileZilla - a FTP client sudo apt-get install -y filezilla ```

Remove duplicate lines from a text file ### Description > Notes: > //...syntax of uniq...// > $uniq [OPTION] [INPUT[OUTPUT]] > The syntax of this is quite easy to understand. Here, INPUT refers to the input file in which repeated lines need to be filtered out and if INPUT isn't specified then uniq reads from the standard input. OUTPUT refers to the output file in which you can store the filtered output generated by uniq command and as in case of INPUT if OUTPUT isn't specified then uniq writes to the standard output. Now, let's understand the use of this with the help of an example. Suppose you have a text file named kt.txt which contains repeated lines that needs to be omitted. This can simply be done with uniq. ###### code ```bash sudo apt install uniq uniq -u input.txt output.txt ``` --- ## 21.

OVERWRITE LOCAL CHANGES ### Description Important: If you have any local changes, they will be lost. With or without --hard option, any local commits that haven't been pushed will be lost.[*] If you have any files that are not tracked by Git (e.g. uploaded user content), these files will not be affected. > Notes: > First, run a fetch to update all origin/ refs to latest: ###### code ```bash git fetch --all ## Backup your current branch: git branch backup-master ## Then, you have two options: git reset --hard origin/master ## OR If you are on some other branch: git reset --hard origin/ ## Explanation: ## git fetch downloads the latest from remote without trying to merge or rebase anything. ## Then the git reset resets the master branch to what you just fetched. The --hard option changes all the files in your working tree to match the files in origin/master git fetch --all git reset --hard origin/master ``` --- ## 28.
