Example

The following example demonstrates the behavior of the verbose shell:

• From the mongo shell, set verbose shell to true:

setVerboseShell(true)

• With verbose shell set to true, run db.collection.aggregate():

db.restaurants.aggregate(
   [
      { $match: { "borough": "Queens", "cuisine": "Brazilian" } },
      { $group: { "_id": "$address.zipcode" , "count": { $sum: 1 } } }
   ]
);

• In addition to returning the results of the operation, themongo shell now displays information about the duration ofthe operation:

{ "_id" : "11377", "count" : 1 }
{ "_id" : "11368", "count" : 1 }
{ "_id" : "11101", "count" : 2 }
{ "_id" : "11106", "count" : 3 }
{ "_id" : "11103", "count" : 1 }
