Using -o json together with -q outputs broken json

[liskaant]

When using quiet mode together with JSON output format the beginning [ is not printed.

As far as I can tell it is caused by the json_prolog function not being called in quiet mode:

nfdump/bin/output_json.c

Lines 79 to 83 in 1f61277

	void json_prolog(void) {
	recordCount = 0;
	memset(data_string, 0, STRINGSIZE);
	printf("[\n");
	} // End of json_prolog

nfdump/bin/nfdump.c

Lines 1129 to 1131 in 1f61277

	if ( !(flow_stat || element_stat || wfile || outputParams->quiet ) && print_prolog ) {
	print_prolog();
	}

The recordCount and memset lines not being called might also cause issues with unitialized variables.

Thanks for the report.
