Learn how to use bash scripting to automate common tasks on Linux, while you study for the related objectives from the RHCE certification exam. This course is part of Grant McWilliam’s comprehensive series that prepares you for the Red Hat Certified Engineer (RHCE) exam—the benchmark certification for Red Hat Enterprise Linux. It covers the foundations of creating and debugging bash scripts, including scripts that accept input via positional arguments, pipes, and file parsing. Plus, learn how to get data out of bash scripts and set up conditional and looping code blocks. Grant also solves some real-world problems, using bash to monitor user space and CPU usage.

Topics include:

  • Basics of bash scripting
  • Bash debugging
  • Loading files in scripts
  • Prompting for input
  • Piping data into a script
  • Outputting data from a script
  • Controlling the flow of bash scripts with conditions
  • Looping bash scripts
  • Reviewing real-world examples
