GIT: find files with odd number of revert commits (used to validate that all merge reverts get reverted back)

odd-revert-finder.sh

#!/bin/bash

FILES="$(git ls-tree -r --name-only HEAD .)"
COUNT=0
IFS="$(printf "\n\b")"
for f in $FILES; do
	NUMBER_OF_LINES=$(git log --oneline --grep=revert $f | wc -l)
	let IS_ODD=$NUMBER_OF_LINES%2
    if [ $IS_ODD -gt 0 ]; 
    	then
    		echo "$f -- $IS_ODD"
    fi
done
