Welcome back to the Linux CLI tools series. Today’s focus is on awk, a versatile text-processing tool, and how to use it to filter out events from a calendar file. This had a specific use case for me, because I wanted to filter out all events from an exported .ics file before a certain date. I needed to import the filtered events to a new calendar and want to avoid duplicating events. So, my main goal: Delete all calendar events before April 1, 2025, from a .ics file, using just the command line.
