+# ruff check
+
+> An extremely fast Python linter. `check` is the default command - it can be omitted everywhere.
+> If no files or directories are specified, the current working directory is used by default.
+> More information: <https://docs.astral.sh/ruff/linter>.
+
+- Run the linter on the given files or directories:
+
+`ruff check {{path/to/file_or_directory1 path/to/file_or_directory2 ...}}`
+
+- Apply the suggested fixes, modifying the files in-place:
+
+`ruff check --fix`
+
+- Run the linter and re-lint on change:
+
+`ruff check --watch`
+
+- Only enable the specified rules (or all rules), ignoring the configuration file:
+
+`ruff check --select {{ALL|rule_code1,rule_code2,...}}`
+
+- Additionally enable the specified rules:
+
+`ruff check --extend-select {{rule_code1,rule_code2,...}}`
+
+- Disable the specified rules:
+
+`ruff check --ignore {{rule_code1,rule_code2,...}}`
+
+- Ignore all existing violations of a rule by adding `# noqa` directives to all lines that violate it:
+
+`ruff check --select {{rule_code}} --add-noqa`
