sync_dualsim.sh

#!/usr/bin/env bash
#
# MIRROR-sync this local `dualsim` folder to the Hugging Face dataset repo.
#
#   Repo: https://huggingface.co/datasets/chen-gao/dualsim
#
# Uses `hf upload --delete "*"` per subtree so the Hub becomes an EXACT MIRROR of
# local: new/changed files are uploaded, and files deleted locally are ALSO deleted
# on the Hub. `hf upload` hashes files, so unchanged files are skipped (only deltas
# transfer). Each run is a versioned commit on the Hub.
#
# --delete is scoped to each subtree's path_in_repo (verified against
# huggingface_hub._prepare_folder_deletions: patterns are matched RELATIVE to
# path_in_repo), so the `eval` sync can never touch `train/` and vice-versa.
#
# Usage:
#   ./sync_dualsim.sh              # mirror meta + eval + train
#   ./sync_dualsim.sh eval         # mirror eval subtree only (fast)
#   ./sync_dualsim.sh train        # mirror train/AgiBotWorld2026 only
#   ./sync_dualsim.sh meta         # push root files (README/.gitattributes/this script)
#   DRY=1 ./sync_dualsim.sh eval   # print what would upload/delete, do nothing
#
# Prereq: `hf auth login` (write token) done once.
