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

从我的bash提示符下执行此操作的最简单方法是什么？

Like this:

mongo <dbname> --eval "db.dropDatabase()"

More info on scripting the shell from the command line here: https://docs.mongodb.com/manual/tutorial/write-scripts-for-the-mongo-shell/#scripting

The best way to do it is from the mongodb console:

> use mydb; 
> db.dropDatabase();

Alternatively, you can stop mongod and delete the data files from your data directory, then restart.

Hint: you can also move the data files to a subfolder, and delete them if you're sure you no longer need them.

You don't need heredocs or eval , mongo itself can act as an interpreter.

#!/usr/bin/env mongo
var db = new Mongo().getDB("someDatabase");
db.dropDatabase();

Make the file executable and run it.
