The video tutorial explains the concept of the Internal Field Separator (IFS) in shell scripting, its default behavior, and how it can be modified to handle different data formats like CSV files. It demonstrates using IFS in while loops to read and process file content line by line, and how to use the AWK command to filter out headers.
