  <info>vendor/bin/rector</info>

To specify a folder or a file, you can run:

  <info>vendor/bin/rector src/Controller</info>

You can also dry run to see the changes that Rector will make with the <comment>--dry-run</comment> option:

  <info>vendor/bin/rector src/Controller --dry-run</info>

It's also possible to get debug via the <comment>--debug</comment> option:

  <info>vendor/bin/rector src/Controller --dry-run --debug</info>
