diff

#!/usr/bin/env bash
set -uo pipefail

# Diff between local ($HOME) and repository
#
# Maintainer: asccigcc
#
# Usage:
#   ./diff

# Run from the repo root so `source config.txt` works from any CWD.
cd "$(dirname "$0")" || exit 1

# Load config variables (files, directories)
source config.txt

# `diff` exits non-zero when inputs differ; `|| true` keeps set -o pipefail happy.
