| # sync-env.sh — Ensure .env has every key from .env.example | |
| # | |
| # Reads .env.example as the source of truth. For any key that is | |
| # missing in the local .env, appends the .env.example value (or | |
| # a placeholder) under the same section comment. Existing keys in | |
| # .env are preserved (never overwritten) so secrets stay intact. | |
| # | |
| # Usage: | |
| # ./scripts/sync-env.sh # sync into .env | |
| # ./scripts/sync-env.sh --check # report missing keys only | |
| # ./scripts/sync-env.sh --target .env.production | |
