Count directories by cases in git repository

find-cases.sh

#!/usr/bin/env bash
set -euo pipefail
[ $# -ge 1 ] || (echo "Expected URI for git clone" >&2 && exit 1)
repodir=`mktemp -d`
git clone -- "$1" "$repodir"
pushd "$repodir" >/dev/null
folders=`git ls-files | xargs -r -d '\n' -n1 dirname | sort | uniq | xargs -r -d '\n' -n1 basename`
popd >/dev/null
rm -rf "$repodir" 
snake_case=`echo "$folders" | grep -- '_' | tee snake | wc -l`
printf "snake\t$snake_case\n"
kebab_case=`echo "$folders" | grep -- '-' | tee kebab | wc -l`
printf "kebab\t$kebab_case\n"
camel_case=`echo "$folders" | grep -E -- '^[a-z0-9]+([A-Z0-9][a-z0-9]+)+$' | tee camel | wc -l`
printf "camel\t$camel_case\n"
pascal_case=`echo "$folders" | grep -E -- '^([A-Z0-9][a-z0-9]+)+$' | tee pascal | wc -l`
printf "pascal\t$pascal_case\n"

Usage: ./find-cases.sh <my-git-repository-uri>
This will print the number of folders it could find in snake, kebab, camel and pascal cases and create files with those names listing the folders so you can ignore certain folders if you want.
