Introducing to Linux Shell

Description: Working with many of the HPC systems in Canada involves using the Linux/UNIX command line. This provides a very powerful interface, but it can be quite daunting for the uninitiated. In this half-day session, you can become initiated with this course. This hands on session will cover basic commands and scripting, as well as touching on some powerful constructs like awk. It could be a great boon for your productivity!

Participants are expected to bring a laptop for hands-on exercises.
