@hemanthbitra Thank you for the report. The original thought was to keep shellcheck quiet, so we passed the argument -S error to only report the errors. As you note, Shellcheck’s warnings are also quite valuable so we’ve removed this flag. Our next release will be reporting errors and warnings. In addition you have the option to customize the shellcheck execution by committing a .shellcheckrc file to your repository.
