Both the getUsers() method and SHOW command can be used to list all users in the Mongo shell.
Case 1 − Using getUsers()
The syntax is as follows −
db.getUsers();
Case 2 − Using show command
The syntax is as follows −
show users;
Let us implement both the syntaxes in order to list all users in the Mongo shell.
Case 1 − The first query is as follows −
> db.getUsers();
The following is the output −
[ { "_id" : "test.John", "user" : "John", "db" : "test", "roles" : [ { "role" : "readWrite", "db" : "test" }, { "role" : "dbAdmin", "db" : "test" } ], "mechanisms" : [ "SCRAM-SHA-1", "SCRAM-SHA-256" ] }, { "_id" : "test.admin", "user" : "admin", "db" : "test", "roles" : [ { "role" : "root", "db" : "admin" } ], "mechanisms" : [ "SCRAM-SHA-1", "SCRAM-SHA-256" ] } ]
Case 2 − The second query is as follows −
> show users;
The following is the output −
{ "_id" : "test.John", "user" : "John", "db" : "test", "roles" : [ { "role" : "readWrite", "db" : "test" }, { "role" : "dbAdmin", "db" : "test" } ], "mechanisms" : [ "SCRAM-SHA-1", "SCRAM-SHA-256" ] } { "_id" : "test.admin", "user" : "admin", "db" : "test", "roles" : [ { "role" : "root", "db" : "admin" } ], "mechanisms" : [ "SCRAM-SHA-1", "SCRAM-SHA-256" ] }
