# This script finds the latest two performance CSV files for a given performance category,
# e.g., `e2e-gas-usages`, in `./test/perf_out`, orders them by their timestamp prefix,
# and calls `perf-diff.sh` to compare them, with before being the older and after the newer file.
# Usage: perf-diff-latest.sh [md|csv]
