[filter] is a list or regex of package names to check (all others will be ignored).
Options:
-d, --dev check only devDependencies
-e, --error-level set the error-level. 1: exits with error code 0 if no errors occur. 2: exits with error code 0 if no packages need updating (useful for continuous integration). Default is 1. (default: 1)
-f, --filter include only package names matching the given string, comma-delimited list, or regex
-g, --global check global packages instead of in the current project
-j, --jsonAll output new package file instead of human-readable message
--jsonUpgraded output upgraded dependencies in json
-l, --loglevel what level of logs to report: silent, error, minimal, warn, info, verbose, silly (default: warn) (default: "warn")
-m, --packageManager npm (default) or bower (default: "npm")
-n, --newest find the newest versions available instead of the latest stable versions
-o, --optional check only optionalDependencies
--packageData include stringified package file (use stdin instead)
--packageFile package file location (default: ./package.json)
--packageFileDir use same directory as packageFile to compare against installed modules. See #201.
-p, --prod check only dependencies (not devDependencies)
--peer check only peerDependencies
-r, --registry specify third-party npm registry
--configFilePath rc config file path (default: ./)
--configFileName rc config file name (default: .ncurc.{json,yml,js})

-t, --greatest find the highest versions available instead of the latest stable versions
--timeout a global timeout in ms
-u, --upgrade overwrite package file
-x, --reject exclude packages matching the given string, comma-delimited list, or regex
-a, --upgradeAll include even those dependencies whose latest version satisfies the declared semver dependency
--semverLevel find the highest version within "major" or "minor"
--removeRange remove version ranges from the final package version
-v, --version 2.15.0
-V
-h, --help output usage information
