Have you ever had to go through a gigantic test file with tons of "fluff", looking for just a few lines out of the ordinary? The lines weren't exactly the same, but you know the structure you were looking for, or the structure of all the fluff you weren't looking for. If you could only sort out the different kinds of structures, everything would be much clearer...
Well, Regular Expressions help you so just that, and apart from being available in many text editors, there are additional things you can do with them using the built in linux/(iOS) tools grep and awk, or Powershell on windows. Join this workshop to get your text-manipulation skills to the next level, and get ready to dazzle your coworkers with the kind of information you can find in multi Megabyte text file in a few minutes.

Key takeaways:
  •  Learn how to filter out just the parts you want from a gigantic logfile, and save them separately. 
  • Learn how to clean away similar recurring phrases from a textfile to find structure and anomalies easier.
