Command: `once-per-save`

Run commands only if they haven’t been run before in this world.

If you are looking for a way to run commands once when you start a new fortress, you probably want on-new-fortress.

This tool is better for commands that you want to run once per world.

You can specify multiple commands to run, separated with `;`, similar to multicmd. However, if the command has been run (successfully) before with `once-per-save` in the context of the current savegame, the commands will not actually run.

## Usage

`once-per-save [--rerun] <command>[; <command> ...]`

  Run the specified commands if they haven’t been run before. If `--rerun` is specified, run the commands regardless of whether they have been run before.

`once-per-save --reset`

  Forget which commands have been run before.
