The course aims to help undergraduates (sophomore to senior) and incoming graduate students quickly get familiar with various computing tools and shell languages in the cost-free Linux (the affinity of Unix) system used mostly in geophysics and seismology community. The students can then use these tools or write their own programs for homework assignments and research studies. The topics covered in the course will be introductory and mainly for Geoscience-majored students but the content should be general and useful enough for other students who need to do programming and computing for their study. In addition, the basic concepts and applications of statistical data analysis, regression, discrete fourier transform, and signal filtering and processing will be also introduced to deomonstrate the functionality of these computing tools.
