Welcome to the course: Linux command line 101

This material

Here you will find the content of the workshop "Command line 101".

Prerequisites

  • You need access to a Linux system.
  • You will use your own computer or any other computer (including computing access at computing centers) you have access to and that runs Linux.
  • The course project will be on Arrhenius, ONLY for those that do not have other access to a computer that runs Linux.

Learning outcome

  • This NAISS course aims to give a brief, but comprehensive introduction to the Linux operating system.

  • What is Linux and why should I use it?

  • You will learn about
  • the command line interface (CLI)
  • navigating and modifying the file tree
    • ls
    • mkdir
    • cd
    • mv
  • editors on the Linux system
  • pipes, sorting, filters
    • redirection
    • pipes
    • etc.
  • patterns
  • scripting

  • some handy hints and tricks

  • This course will consist of lectures and type-alongs, as well as a few exercises where you get to try out what you have just learned.

  • This course has been somewhat reworked based on previous participant input. We would be grateful if you will fill the evaluation survey so we can further improve the course: https://forms.cloud.microsoft/e/Bhq1g06R05.

Cluster-specific approaches

The course is given by application experts from several NAISS branches. It is agnostic, but the course project for those who do not have their own Linux access will the NAISS system "Arrhenius". There is a Get started guide for Arrhenius here.

  • The login node for Arrhenius is login.hpc.arrhenius.naiss.se for regular SSH connections. More info here: Terminal login.
  • There is also ThinLinc access. Use tl.hpc.arrhenius.naiss.se as server. More information here: ThinLinc info.

Important info

  • There is an "important info" page for this course, containing info on the course project. It can be found here: https://nextcloud.naiss.se/s/iffFCJxy2diP9gc
  • There is a Q/A page for use during the lectures. Since the lectures are recorded, you may get recorded if you ask questions in the Zoom, but you can always write questions on the Q/A and get answers there. It also has the advantage that you can go back and look at the answers later. The Q/A page can be found here: https://nextcloud.naiss.se/s/2KJXbN2NmESEYKw

Preparations

In order to type along and do the exercises, please prepare your course environment now:

  1. Login to the system you are using (NAISS system, Arrhenius, your own computer, other system)
  2. Create a directory to work in (mkdir intro-linux) and then switch to it (cd intro-linux)
  3. Download the exercises with wget https://gitlab.naiss.se/hpc/training/linux-command-line-101/-/raw/main/exercises.tar.gz
  4. Check the contents of the file tar tzvf exercises.tar.gz
  5. Extract the exercises with tar xzvf exercises.tar.gz
  6. Enter the directory that was created: cd exercises

Remark: By default the utility wget is not installed on a Mac. You can download from the website: https://gitlab.naiss.se/hpc/training/linux-command-line-101/-/raw/main/exercises.tar.gz and move the file: mv ~/Downloads/exercises.tar.gz . instead of step 3.
