mongo

the Mongo command-line tool

- Connect to a database:

- Connect to a database running on a given host on a given port:
mongo --host [host] --port [port] [database]

- Connect to a database with a given username; user will be prompted for password:

mongo [OPTIONS] [DB_ADDRESS] [FILE+]

mongo is a JavaScript shell (with GNU readline capabilities). It supports interactive and non-interactive use. When used interactively, JavaScript can be used to query the database or perform any other function normally available with SpiderMonkey. Database output is displayed in JSON format.

If JavaScript files are specified on the command line, the shell will run non-interactively, running each one in sequence and then exiting.
