Ok Actually I am looking how to use magic commands in same way as dbutils  . For Instance 

 dbutils.fs.head('dbfs:/FileStore/<<name>>.csv',10) Gives 10 bytes  I am looking for magic command like how to give second parameter   %fs head dbfs:/FileStore/hotel_data.csv 10(If we give upto 10) it works but when we pass second one like 10 it will not give output like 10 bytes as above
