      -t <level>          : enable tracing with level from 1-3
      -o <outStream>      : OUT|ERR , ERR is default
      -s <path:path...>   : <topSchema>(:<referencedSchema)+
      -w <path>           : workspace directory
      -c                  : compact output for jq and extract commands
      -r                  : raw string output for jq and extract commands
      -m <memberName>     : member name to find the zowe config in each PARMLIBs specified
      -p <configPath>     : list of colon-separated configPathElements - see below
    commands:
      extract <jsonPath>  : prints value to stdout
      validate            : just loads and validates merged configuration
      env <outEnvPath>    : prints merged configuration to a file as a list of environment vars
    configPathElement:
      PARMLIB(datasetName) - a library that can contain config data
      FILE(filename)   - the name of a file containing Yaml
      PARMLIBS         - all PARMLIBS that are defined to this running Program in ZOS, nothing if not on ZOS

echo $?
12

With fix

Missing *** unknown option *** '-h' in the output and echo $? -> 0

Note

-c and -r are flags too, but also using getStringOption(). This might need some review too.
