Workshop Description (Introductory Course)

Unix is a command-line-based platform that is a highly powerful and flexible tool for data management and analysis. First, this workshop introduces the basic concepts of UNIX operating system and shell scripting. We will explore essential hands-on skills to confidently use the command line interface on either a local (laptop) or a remote (hoffman2 cluster) computer running the Unix system. Next, this workshop covers how to navigate around the Unix file system from the command line and use a number of basic, common Unix commands. The course is supplemented with many hands-on examples. No prior knowledge of Unix or programming is required.

Workshop Materials

  • Learning the fundamentals of Unix
  • Understand the underlying philosophy of Unix and command line interface
  • Login and log out of a Hoffman2 Cluster (Unix file system)
  • Navigate through the Unix file system

Slides: Day 1

  • Use the productivity features of the Unix shell
  • Create and modify files using Unix editor
  • Copy, rename, and display files

Slides: Day 2

  • Use tools for processing text files
  • Edit files in non-interactive mode using sed
  • Process tab delimited files using awk
  • Write simple shell scripts
  • Submit jobs via qsub on hoffman2

Slides: Day 3

I really loved that she shared advice on the best way to learn about new commands/modules, which are often very inaccessible to beginners. Going forward I feel that I have a really strong foundation in UNIX command line, and working with bioinformatics data in general, that I can build upon. Perfect introduction course for those that want to learn bioinformatics!
It’s a great workshop. Highly recommend for whoever wants to learn -omics analysis without any programming background!

It was great! I have learned a lot!

I learned much more than when I tried to learn this on my own!

This has been a great experience, it was very easy to follow and the instructor was phenomenal! I learned a lot and I feel much more comfortable opening a terminal and learning how to work with it now.
