  • I tried this and the output was just every line in the text file, regardless of whether or not it included ERROR. It's entirely likely I did something wrong, as I mentioned I'm new to all this. Commented Jul 14, 2016 at 17:14
  • @Patremagne : Murphy and I, we both basically use the same algorithm. I haven't run his version, but on first glance it looks correct . You may have missed, that his version filters for ERROR|INFO|WARN, and trailing lines Commented Jul 14, 2016 at 17:18
  • @AlexStragies the only small difference is, that I remove the line breaks in case of an indent. this way everything is in one line and easier to process with grep if necessary Commented Jul 14, 2016 at 17:21
  • @AlexStragies Ahh I missed that INFO was in the perl script, so I removed it and it worked on my test text file that only includes 10 or so lines from the actual log. Unfortunately when I try it on the log itself, there's no output. Commented Jul 14, 2016 at 17:26
  • @Patremagne I tested my solution with my provided example.log. It puts out the data as shown above. Commented Jul 14, 2016 at 17:31
