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
