Summary

  • Experience in scripting: The scripts I have created or modified were to help automate tasks as a systems administrator: Tracking disk space usage, Searching logs for troubleshooting system problems, Rotating and truncating log files, Making IP/MAC address lists for network validation, Creating scripts to configure network interfaces for newly built Virtual Machines, Searching port numbers for tasks connected to them
  • Scripting languages I have used: Python, Ruby, and BASH.
  • I can write a script from scratch if needed, but I find it faster and easier to use Google to find something written and then modify as needed for the task at hand.
