• Rewrite code matching a pattern:

ast-grep run {{[-p|--pattern]}} '{{pattern}}' {{[-r|--rewrite]}} '{{replacement}}' {{path/to/file}}

• Run rules from a configuration file:

ast-grep scan {{[-r|--rule]}} {{path/to/rule.yml}} {{path/to/directory}}

• Interactively search and rewrite code:

ast-grep run {{[-p|--pattern]}} '{{pattern}}' {{[-i|--interactive]}} {{path/to/directory}}
