The result is that when doing shell completion (bash and zsh only), instead of getting no suggestions for commands that take no more arguments, the user will instead be shown an informative message: $ helm list <TAB> This command does not take any more arguments (but may accept flags).

Verify that the given chart has a valid provenance file.

Provenance files provide cryptographic verification that a chart has not been

tampered with, and was packaged by a trusted provider.

'--verify' flags that run the same validation. To generate a signed package, use

the 'helm package --sign' command.
