greprate

Given a continuous input, greprate will display the rates at which matches to a given regular expression occur.

This project is currently very alpha, and should be viewed as a proof of concept.

Examples

$ (while true; do echo hello $((RANDOM % 10 + 1)); sleep 0.1; done) | greprate 'hello (\d+)'
