setVerboseShell() takes one boolean parameter. Specify true or leave the parameter blank to activate the verbose shell. Specify false to deactivate.

Example

The following example demonstrates the behavior of the verbose shell:

From mongosh, 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, mongosh now displays information about the duration of the operation:
```
{ "_id" : "11377", "count" : 1 }
{ "_id" : "11368", "count" : 1 }
{ "_id" : "11101", "count" : 2 }
{ "_id" : "11106", "count" : 3 }
{ "_id" : "11103", "count" : 1 }
