This one downloads the script at the given URL, and then the Ruby interpreter executes it. The rest of this command (the curl command) is a tool to make web requests from your command line. Let’s start by copying and pasting the following command into our command line: /usr/bin/ruby -e "$(curl -fsSL )"ĭon’t worry about what all that does-as long as you’re using MacOSX 10.7 or higher, the Ruby interpreter comes pre-installed. If you already have Homebrew installed, you can skip to Installing PostgreSQL.
To install PostgreSQL on the command line we will be using a package manager called Homebrew.
For this tutorial, let’s see how to install on the command line. You can pick whichever option is right for you.
Aside from standard relational database features, some of the most notable features in Postgres are: Postgres supports a long list of database features, including several enterprise features.
Its unique combination of simplicity and power makes it a popular choice for individual users and small businesses, but enterprise businesses like Yahoo, Uber, Disqus, and TripAdvisor as well.
It is high performance and highly scalable, capable of handling huge amounts of data and high-load internet applications with thousands of concurrent users. It runs on nearly any operating system including Linux, Unix, and Windows. Put simply, it is a database that allows you to relate one piece of data to another (thus, “relational”). PostgreSQL is an ACID-compliant Object Relational Database Management System, or ORDBMS (quite a mouthful!). Know how to use both command-line and UI tools to manage your database.Know how to create and manage databases and users.Have a running PostgreSQL 9.5.4 instance.You will need at least a basic level of comfort using the command line using either the MacOSX built-in terminal, iTerm2, Zsh, or something similar. This tutorial will teach you how to set up, configure, and use PostgreSQL on MacOSX 10.7 (Lion) and above. If you’re here reading this tutorial, hopefully, you are trying to do the same! The other day I began a new Node.js project and wanted to use PostgreSQL as my database backend. There are the original command-line tools, and there are many graphical user interfaces of varying capabilities. There are a lot of different ways to use Git. # Commit all changes and add a message that describes the commit: git commit -m "added test1.txt" However, you still need to commit this change. If you recheck the git status now, you would see that the file is now being tracked (as it changed from red to green). #Prompt Git to track the new file by running: git add test1.txt Git is tracking the folder in which the file was added, and notifies you that the changes are not being tracked. The output tells you there are untracked files inside the directory and lists file1.txt. #Add some files inside NewFolder and see how the git status changes: touch file1.txt Since the folder we created doesn’t have any files in it, the output responds with: nothing to commit. This shows the state of the working directory and displays if any changes made inside the directory. # While in the directory NewFolder, type the following command: git status Running the git init command initializes an empty git repository in this particular location. #As we want to keep track of changes inside this folder, we need to create a local Git repository for it. The path may differ according to the location where you created the new folder. mkdir /Users//Desktop/Tools/Git/NewFolder #First, open the terminal and create a new folder named NewFolder. To demonstrate how to work with files on local Git repositories, we are going to create a demo folder and file to work with. Then, add your email: git config -global user.email and Commit Changes Open the terminal and configure your GitHub username: git config -global user.name “your_github_username”
