Behind the scenes

How are identified applicable files

If this linter is active, all files will always be linted

How the linting is performed

trufflehog is called once on the whole project directory (project CLI lint mode)

filtering can not be done using MegaLinter configuration variables,it must be done using trufflehog configuration or ignore file (if existing)
VALIDATE_ALL_CODEBASE: false doesn't make trufflehog analyze only updated files

Example calls

trufflehog filesystem .
