 ### Description
 
-This repository has teaching materials for a **3 hour**, hands-on **Intermediate bash** workshop led at a relaxed pace. Many tools for the analysis of big data require the use of a high performance compute cluster and a knowledge of the command line. In this workshop we invite users of the HMS Research Computing Cluster O2 and members of the Harvard community who are interested in using a compute cluster to join us as we demonstrate some very helpful tips and best practices. We will introduce participants to various commands and approaches to help effectively navigate use the cluster and complete tasks in an efficient manner.
