Bash Shell Scripting - Using "I" (pipe) - sort & uniq Commands

The video tutorial demonstrates how to use the pipe symbol to connect Linux commands, focusing on a scenario where two files contain animal names written by David and Kevin. The tutorial explains how to count lines using the WC command, analyze file content for duplicates, and use sort and unique commands to filter data. Ultimately, it determines the winner based on unique animal names and emphasizes the practical application of these techniques.
