#11 Pipes and the Unix Philosophy - Introduction to Linux Command Line

In this video, we explore pipes in Linux — one of the most powerful ideas in the Unix world.
Pipes allow you to take the output of one program and feed it directly as input to the next. This lets you chain simple commands together to perform more complex tasks, all from the command line.

We start with a quick recap of input/output redirection, then move into:

How pipes work in Bash

Treating programs as filters

Combining commands to build processing pipelines

The Unix philosophy: small programs that do one thing well
Sending stdout only, stderr only, or both through pipelines
Using tools like cat, sort, uniq, tr, and aspell together
How to clean and normalize text using pipelines
How process substitution allows piping only stderr
By the end of the video, you’ll understand how to create powerful command chains that transform data step by step — the way Unix was designed to be used.

👉 In the next video, we’ll explore essential filters like grep, wc, head, tail, sort, and more.
