If a Rubocop rule is disabled in-line does it need to be re-enabled

Question

If you disable a Rubocop rule in-line and do not re-enable it, will the rule be disabled for all subsequence files or is an in-line disable limited to the scope of the current file?

For example, if I enter this before a couple of methods that I know break the line length rule:

# rubocop:disable Metrics/LineLength

Is this rule disable for the rest of the file, or for all subsequent files in the current scan?

Answer 1

In-line config is applied to the given file only (just tested it).
