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 00:00 - Introduction 00:30 - Text Editors 01:50 - cat 02:25 - stdout 03:13 - echo 04:05 - stdin 05:20 - stderr 06:55 - wc 07:40 - Pipe 08:05 - tee 09:45 - /dev/null 10:35 - grep 15:10 - CSV files 16:10 - less, head, tail 17:35 - TSV files 18:00 - sed 21:20 - cut 23:55 - sort & uniq 25:50 - split 28:18 - Up Next 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. Up next: File permissions and system information commands!
