Review Summary
The script has critical issues that need fixing. First, --result-file should be replaced with -r (the standard short form) or shell redirection > for better compatibility. Second, for the ShopDBDevelopment backup, you must use --no-create-info instead of --no-create-db — the current flag only skips CREATE DATABASE statements but still includes CREATE TABLE definitions, which violates the requirement to exclude all schema from the development environment. Third, when restoring to ShopDBDevelopment, you need to either add USE ShopDBDevelopment; at the beginning of the SQL file or specify the database name explicitly in the mysql command (e.g., mysql ShopDBDevelopment < backup.sql). These are functional blockers that will cause the script to fail or produce incorrect results.

The --result-file flag is not valid for mysqldump - it's used by the mysql client. Use -r filename.sql or shell redirection > filename.sql instead.

Using --no-create-db only skips CREATE DATABASE statements but still includes CREATE TABLE statements. For the development environment where schema should NOT be copied, use --no-create-info instead, which excludes all schema (CREATE TABLE, etc.) and dumps only data.

When restoring to ShopDBDevelopment, the backup file (created with corrected --no-create-info) contains only INSERT statements without any USE statement. You need to either add USE ShopDBDevelopment; to the beginning of the SQL file, or pipe through mysql with the database name explicitly specified.

Review Summary
The restore command for ShopDBDevelopment is using --databases flag with the mysql client, but --databases is only valid for mysqldump, not mysql. This causes the error: mysql: [ERROR] unknown option '--databases'. Since the backup was created with --no-create-info (no CREATE DATABASE statements), you need to specify the database name directly in the mysql command: mysql -u "$DB_USER" -p"$DB_PASSWORD" ShopDBDevelopment < backup-no-create-info.sql. This is a functional blocker that prevents the script from executing successfully.

Remove --databases flag and specify the database name directly. Since the backup was created with --no-create-info, it contains no CREATE DATABASE statements, so --databases flag is inappropriate. Use mysql ... ShopDBDevelopment < backup-no-create-info.sql instead.
