Did you consider bash's -e option?

Quote:

-e Exit immediately if a pipeline (which may consist of a single simple command), a list, or a compound command (see SHELL GRAMMAR above), exits with a
non-zero status. The shell does not exit if the command that fails is part of the command list immediately following a while or until keyword, part of
the test following the if or elif reserved words, part of any command executed in a && or || list except the command following the final && or ||, any
command in a pipeline but the last, or if the command's return value is being inverted with !. If a compound command other than a subshell returns a
non-zero status because a command failed while -e was being ignored, the shell does not exit. A trap on ERR, if set, is executed before the shell
exits. This option applies to the shell environment and each subshell environment separately (see COMMAND EXECUTION ENVIRONMENT above), and may cause
subshells to exit before executing all the commands in the subshell.

NAME

       mongo - the Mongo command-line tool

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)
