The Complete Practical Docker Guide - Data Streams of the Process

This video tutorial explains how to use process utilities like PS top and Edge top. It introduces the concept of data streams in processes, specifically stdin, stdout, and stderr, and how they function. The tutorial demonstrates how to redirect these streams to different processes and provides practical examples using the LS and Mkdir commands. The video concludes with a summary of key points and a preview of the next lecture.
