Like `ls -1` but marks path modified by a specific author or a company

ls-contributed-to.sh

#!/bin/bash

#regex="@nina.no$"
regex="$1"

function check {
  git log --format="%ae" "$1" | grep -q "$regex"
}

check '.' && echo " * ." || echo "  ."
for path in *
do
  check "$path" && echo -n " * " || echo -n "   "
  ls -1 --color=always | grep --color=never "$path" | sort -n | head -n1
done
