How do I drop a MongoDB database from the command line?

MongoDBDatabaseBig Data Analytics

To drop a MongoDB database from the command line, use the following syntax:

mongo yourDatabaseName --eval "db.dropDatabase()"

To understand the above syntax, let us display all the database from MongoDB. The query is as follows −

> show dbs;

The following is the output −

StudentTracker 0.000GB
admin 0.000GB
config 0.000GB
local 0.000GB
sample 0.000GB
test 0.003GB

Drop the database with the name ‘StudentTracker’. The query is as follows to drop a database from command line −

C:\Program Files\MongoDB\Server\4.0\bin>mongo StudentTracker --eval "db.dropDatabase()"

The following is the output −

MongoDB shell version v4.0.5
connecting to: mongodb://127.0.0.1:27017/StudentTracker?gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("afc34e93-b4c0-46f0-85bd-b80ed17b8c11") }
MongoDB server version: 4.0.5
{ "dropped" : "StudentTracker", "ok" : 1 }

Now check the database has been dropped or not. The query is as follows −

> show dbs

The following is the output −

admin 0.000GB
config 0.000GB
local 0.000GB
sample 0.000GB
test 0.003GB

Look at the sample output, the database ‘StudentTracker’ has been dropped.
