      # Learning Objectives
      *After completing the work in this module you will be able to:*
      1. Run commands more efficiently by using advanced features of the Bash shell, shell scripts, and various Red Hat Enterprise Linux utilities.
      1. Run repetitive tasks with `for` loops, evaluate exit codes from commands and scripts, run tests with operators, and create conditional structures with `if` statements.
      1. Create regular expressions to match data, apply regular expressions to text files with the `grep` command, and use `grep` to search files and data from piped commands.

      # Key Takeaways
      1. Create and execute simple Bash scripts to accomplish simple administration tasks.
      1. Use loops to iterate through a list of items from the command line and in a shell script
      1. Use conditional structures to incorporate decision-making into shell scripts.
      1. Search for text in log and configuration files by using regular expressions and the `grep` command.
