   meta get [command options] [arguments...]

OPTIONS:
   --external value, -e value        MetaFile pipeline meta (default: "meta")
   --skip-fetch, -F                  Used with --external to skip fetching from lastSuccessfulMeta when not triggered by external job
   --json-value, -j                  Treat value as json. When false, set values are treated as string; get is value-dependent and strings are not json-escaped

   --sd-api-url value, -u value      Set the SD_API_URL to use in SD API calls (default: "https://api.screwdriver.cd/v4/") [$SD_API_URL]

   --skip-store                      Used with --external to skip storing external metadata in the local meta
   --cache-local                     Used with external, this flag saves a copy of the key/value pair in the local meta
