Building upon the content of “PACE – Linux 101”, this monthly class is designed to extend the command-line capabilities of PACE users so that they can more efficiently address computational research in a Linux environment. After taking this class, users will be able to demonstrate their ability to utilize regular expressions for stream manipulation with tools like sed and awk, compile code from source with version control and build utilities such as git and make, implement advanced I/O manipulation for in-situ processing, and integrate advanced compression with system tools for better data management. This is a hands-on class that will provide the users to follow the instructor through in-class examples, work through a template research-driven exercise, and ask questions as they arise.
