Linux Introduction
This page provides an introduction to the elements of working at the Linux command line and Bash scripting that are most relevant for users of the computing clusters managed by Research Computing Services (RCS) as well as Compute Canada. Working at the command line is an extremely valuable skill for anyone who handles and processes large collections of data. (Nature - Five Reasons Why Researchers Should Learn to Love the Command Line) The command line is a text-only interface that emphasizes automation of complex tasks through simple scripts or short sequences of commands. Relative to working with a graphical interface, it is somewhat less intuitive and takes some time to learn. However, with a few days of work it is possible to become proficient enough to be comfortable working on HPC systems.
