The Lint/RedundantCopEnableDirective cop needs to be disabled so as

to be able to provide a (bad) example of an unneeded enable.

rubocop:disable Lint/RedundantCopEnableDirective

This cop detects instances of rubocop:enable comments that can be removed.

When comment enables all cops at once rubocop:enable all that cop checks whether any cop was actually enabled.

Example:

# bad
foo = 1
# rubocop:enable Layout/LineLength

# good
foo = 1

Example:

# bad
# rubocop:disable Style/StringLiterals
foo = "1"
# rubocop:enable Style/StringLiterals
baz
# rubocop:enable all

# good
# rubocop:disable Style/StringLiterals
foo = "1"
# rubocop:enable all
baz
