   • Examples of command chains for efficient data processing

2. Lesson: Input/Output Redirection

   • Redirecting command output to a file using >
   • Appending command output to a file using >>
   • Redirecting input from a file using <
   • Combining input/output redirection and command chaining

3. Lesson: Powerful Command-Line Filters

   • Using grep to search for specific patterns in files
   • Filtering and processing text using regular expressions
   • Extracting specific columns of data using awk
   • Stream editing with sed for search and replace operations

4. Exercise: Command Chains and Filters

   • Create command chains to process and filter data
