The shell (or command-line) is the most commonly used (for advanced operations) interface to Unix-like operating systems. In this session we'll introduce some of the most commonly used command-line/shell features and how they may be used in a hypothetical research project, using real astronomical data sets. The session plan (with a listing of used commands and short explanation) is available here: https://gitlab.com/makhlaghi/smack-talks-iac/-/blob/master/smack-2-shell.md

An introduction to the Unix-like operating systems, starting with a review of the very interesting history behind it.

Hands-on introduction on the inner working of NoiseChisel by Dr. Mohammad Akhlaghi. NoiseChisel is a program in GNU Astronomy Utilities (Gnuastro) that is in charge of separating signal from noise in a 2D image or 3D datacube (and as a side-effect, measuring an accurate background level for the data). This video was made with Gnuastro 0.15 (released on 2021-05-31). Updates in NoiseChisel will be published in the Gnuastro manual (discussed in video).
