Bash script to return exit code from NodeJs script

Question

I have a Bash script which runs a node script as part of its tasks. I would like the bash script to exit with the same exit code as the node script. Simplified example below.

foo.sh:

#!/bin/bash
node ./bar.js

bar.js:

process.exit(1); //sometimes the exit code can be 0

From: http://www.tldp.org/LDP/abs/html/exit-status.html

When a script ends with an exit that has no parameter, the exit status of the script is the exit status of the last command executed in the script

which implies that you simply need to add "exit" to your above script.

#!/bin/bash
node ./bar.js
exit
