Slice and dice log files on the command line.

Angle-grinder allows you to parse, aggregate, sum, average, min/max, percentile, and sort your data. You can see it, live-updating, in your terminal. Angle grinder is designed for when, for whatever reason, you don’t have your data in graphite/honeycomb/kibana/sumologic/splunk/etc. but still want to be able to do sophisticated analytics.

Installation Steps:

1. Open Terminal using Spotlight search by pressing  <command+space>.
   Type terminal and hit  Enter key.
2. Now, run
   ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)” < /dev/null 2> /dev/null
3. Install angle-grinder using brew
   brew install angle-grinder

angle-grinder is ready to use now!

Angle grinder can process well above 1M rows per second (simple pipelines as high as 5M), so it’s usable for fairly meaty aggregation. The results will live update in your terminal as data is processed. Angle grinder is a bare bones functional programming language coupled with a pretty terminal UI.
