How to identify disk space consumed for a particular directory pattern using hdfs command without listing all files under that directory?

How hdfs dfs -du -h command can be clubbed efficiently with other command to get disk space consumed for particular directory pattern?

Example like: hdfs dfs -du -h /data/timestamp=201901* should give me disk space consumed for that pattern for the month of January 2019 ?

hdfs dfs -du -h /data/timestamp=201901*
