Behind the scenes

How are identified applicable files

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

How the linting is performed

secretlint 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 secretlint configuration or ignore file (if existing)
VALIDATE_ALL_CODEBASE: false doesn't make secretlint analyze only updated files

Example calls

secretlint "*/**"

secretlint --secretlintrc .secretlintrc.json "**/*"
