Usage: ncu [options] [filter]

[filter] is a list or regex of package names to check (all others will be ignored).

Options:
  --configFilePath <path>      rc config file path (default: directory of `packageFile` or ./ otherwise)
  --configFileName <path>      rc config file name (default: .ncurc.{json,yml,js})
  --cwd <path>                 Used as current working directory for `spawn` in npm listing
  --dep <dep>                  check only a specific section(s) of dependencies: prod|dev|peer|optional|bundle (comma-delimited)
  -e, --error-level <n>        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)
  --engines-node               upgrade to version which satisfies engines.node range
  -f, --filter <matches>       include only package names matching the given string, comma-or-space-delimited list, or /regex/
  -g, --global                 check global packages instead of in the current project
  -i, --interactive            Enable interactive prompts for each dependency; implies -u unless one of the json options are set
  -j, --jsonAll                output new package file instead of human-readable message
  --jsonDeps                   Will return output like `jsonAll` but only lists `dependencies`, `devDependencies`, and `optionalDependencies` of the new package data.
  --jsonUpgraded               output upgraded dependencies in json
  -l, --loglevel <n>           what level of logs to report: silent, error, minimal, warn, info, verbose, silly (default: warn) (default: "warn")
  -m, --minimal                do not upgrade newer versions that are already satisfied by the version range according to semver
  -n, --newest                 find the newest versions available instead of the latest stable versions

  --packageFile <filename>     package file location (default: ./package.json)
