Welcome to the course: Command Line 101¶
This material
Here you will find the content of the workshop “Command Line 101”.
- Documentation about Linux at some of the Swedish HPC centres
- HPC2N: https://docs.hpc2n.umu.se/tutorials/linuxguide/
- UPPMAX: https://docs.uppmax.uu.se/getting_started/linux/
- LUNARC: https://lunarc-documentation.readthedocs.io/en/latest/guides/linux/linux_basics_intro/

Prerequisites
- You need access to a Linux system.
- The course project will be on Tetralith, but you can use your own computer or any other computer you have access to that runs Linux.
- For those using Tetralith, there is a Get started guide for NSC here.
Content
- This NAISS course aims to give a brief, but comprehensive introduction to the Linux operating system.
- You will learn about
- the command line
- navigating the file system
- editors on the Linux system
- data handling
- 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.
- It is the first instance of this course, so we will be grateful if you will fill the evaluation survey so we can improve the course: https://forms.office.com/e/n2ss7F4h3C.
Cluster-specific approaches
The course is given by HPC2N (Kebnekaise), but will be done under NAISS on the NAISS system “Tetralith”. There is a Get started guide for NSC here.
- The login node for Tetralith is
tetralith.nsc.liu.se. - It looks like this when I login the first time from my computer “defiant”:
bbrydsoe@defiant:~$ ssh x_bibr@tetralith.nsc.liu.se The authenticity of host 'tetralith.nsc.liu.se (2001:6b0:17:140::1:10)' can't be established. ECDSA key fingerprint is SHA256:dwFmOFzy59e+OdZmMLAW3fj+GeMGACYwjPgc7LKZgSU. Are you sure you want to continue connecting (yes/no/[fingerprint])? yes Warning: Permanently added 'tetralith.nsc.liu.se,2001:6b0:17:140::1:10' (ECDSA) to the list of known hosts. Password: Verification code: - The verification code it askes about is a 2FA that you need to set. See here: https://www.nsc.liu.se/support/2fa/.
- The project storage for the course project is in
/proj/intro-linux/users/YOUR-USERNAME.
Important info¶
- There is an “important info” page for this course, containing info on the course project, login info for Tetralith, etc. It can be found here: https://umeauniversity.sharepoint.com/:w:/s/HPC2N630/Ed16r0fqgGpLm6T2u-bl5yIBZjmV_GvBy-EOsg9fcWK-UQ?e=LDLQX4
- 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://umeauniversity.sharepoint.com/:w:/s/HPC2N630/EQUtySAkcGREswBAeZiGJgUBilEListST0Oftyf2FqSnSg?e=DPcQoP
