MongoDB drop every database

Question

I would like to know if there're a command to drop every databases from my MongoDB?

I know if I want to drop only one datatable, I just need to type the name of the database like the code below but I dont want to have to specify it.

mongo DB_NAME --eval 'db.dropDatabase();' 

Answer 1

you can create a javascript loop that do the job and then execute it in the mongoconsole.

var dbs = db.getMongo().getDBNames() for(var i in dbs){     db = db.getMongo().getDB( dbs[i] );     print( "dropping db " + db.getName() );     db.dropDatabase(); } 

save it to dropall.js and then execute:

mongo dropall.js 

Answer 2

Try this command:

mongo --quiet --eval 'db.getMongo().getDBNames().forEach(function(i){db.getSiblingDB(i).dropDatabase()})'
