Tell us about your environment

• ESLint Version: master
• Node Version: 8.8.0
• npm Version: 5.4.2

What parser (default, Babel-ESLint, etc.) are you using?

default

Please show your full configuration:

# foo.yml

rules:
  semi: 2

# .eslintrc.yml

rules:
  no-console: 2

What did you do? Please include the actual source code causing the issue, as well as the command that you used to run ESLint.

console.log('foo');

eslint -c foo.yml foo.js

What did you expect to happen?

I expected no errors to be reported, because I used the -c flag to specify a config, so I did not expect ESLint to also look for other config files in the filesystem.

What actually happened? Please include the actual, raw output from ESLint.

1:1   error  Unexpected console statement         no-console

In addition to the config file specified with -c, ESLint also looked for .eslintrc files in the current directory, so the no-console rule was enabled.
