Practical Linux Command Line 2.0 - Pipe with Examples

The video tutorial explains how to use pipes in the command line to chain multiple commands together, redirecting the output of one command to the input of another. It provides examples using the 'WC' and 'grep' commands, demonstrating how to count lines and search for specific text. The tutorial also covers chaining multiple pipes and redirecting output to files. An exercise is provided to practice these concepts, followed by a detailed solution.
