Created January 16, 2023 10:10
Simple script outputting who likely has the most knowledge about an area of your code base
#!/bin/bash
##
# Outputs the top 10 committers on the provided area, for the period provided,
# based on the number of commits, in the form of 4 columns:
# Lines added, Lines deleted, Number of commits, Author
# (This allows for easily re-sorting the output by piping it into `sort -nr -k COLUMN_NUMBER`)
#
# Tip: replace tabs with commas everywhere below to output valid CSV content.
