About This Class

699b1d62

This beginner friendly course is specifically designed to show you how to use Bash commands and shell programming to handle textual data which can be a csv format data or systems log file. In this course you will  learn Bash by doing projects. 

However, you need to understand the fact that Bash may not the best way to handle all kinds of data! But there often comes a time when you are provided with a pure Bash environment, such as what you get in the common Linux based Super-computers and you just want an early result or view of the data before you drive into the real programming, using Python, R and SQL, SPSS, and so on. Expertise in these data-intensive languages also comes at the price of spending a lot of time on them.

In contrast, bash scripting is simple, easy to learn and perfect for mining textual data! Particularly if you deal with genomics, microarrays, social networks, life sciences, and so on. It can help you to quickly sort, search, match, replace, clean and optimise various aspect of your data, and you wouldn’t need to go through any tough learning curves. We strongly believe, learning and using Bash shell scripting should be the first step if you want to say, Hello Big Data!

Authored by Ahmed Arefin, PhD and thankfully voiced by A. Collinwood (voice artist). This course is a core component of the 'Learn Scientific Programming' initiative.
