-------------------------------------------------
Thanks [~linyiqun] for review...
Attached updated patch v5...
This command will not print anything if it fail to get service IDs from
configuration, so I added one check.
{code}
+ if (targetIds.isEmpty()) {
+ errOut.println("Failed to get service IDs");
+ return -1;
+ }
{code}
Please review...
