SYNOPSIS

       mongo [OPTIONS] [DB_ADDRESS] [FILE+]

DESCRIPTION

       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  dis-
       played 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.

EXAMPLES

       mongo  start the shell, connecting to the server at localhost:27017 and using the test database

       mongo foo
	      start the shell using the foo database at localhost:27017

       mongo 192.169.0.5/foo
	      start the shell using the foo database at 192.169.0.5:27017

       mongo 192.169.0.5:9999/foo
	      start the shell using the foo database at 192.169.0.5:9999

       mongo script1.js script2.js script3.js
	      run three scripts and exit

OPTIONS

       --shell
	      run the shell after executing files

       --help show usage information

       --host HOST
	      server to connect to (default HOST=localhost)

       --port PORT
