Pre2b: BASH Essentials | Redirection | File Processing
Linux for Beginners.
BASH tutorial.
In this video, we will look at BASH redirection and text manipulation — essential skills for anyone working on Linux. Whether you're a researcher, developer, or just getting started with the terminal, this guide walks you through tools like cat, echo, tee, grep, sed, cut, sort, uniq, and split.
You’ll learn:
How standard streams (stdin, stdout, stderr) work
Using tee to both view and save output
Basic pattern searching with grep and regular expressions
Modifying text in files using sed
Extracting and manipulating columns using cut
Finding unique values and sorting data using sort and uniq
Splitting large files into smaller chunks using split
We’ll work with files like CSVs, simulate simple datasets, and show how these tools fit into data analysis workflows.
Perfect for Linux beginners, students, or researchers looking to improve their command-line skills.
