User experience rebasing a working branch to origin/master after we've merged (currently AKA: origin/kevin-eol-cleanup)

steps to do big updates to a .gitattributes file.bash

# update the .gitattributes
git add .gitattributes
git commit -am "cleaning up line endings"

# force Git to re-index everything
rm .git/index
git reset
git add -u

# now modify that commit
git commit --amend

steps to find files with certain endings.bash

grep -rlUP "\r$" * | grep -i "\.json"
grep -rlUP "\r$" * | grep -i "\.m" | grep -v "PacletInfo\.m" | sed -e "s/\/.*//" | sort | uniq -c | sort
