Command Line: Introduction

beginner bash hpc data science


Overview

Using the command line (aka Unix shell, or terminal) is fundamental to using both your computer and more powerful cloud and cluster computational resources effectively. Whether using Quest (Northwestern’s high performance computer cluster), managing software and package installations locally, interacting with databases, using version control systems like git, or running machine learning models in the cloud, being comfortable with the command line will open up new computational possibilities.
