Bash Question

Running node from a bash script

Quite simply, I'm attempting to automate running a nodejs script using cron, however the script itself doesn't seem to be able to run the file. My script is simple:

#!/usr/bin/env node
node /var/node/assets/js/update.js

However, in running this, it returns that the beginning of the pathing is incorrect:

node /var/node/assets/js/update.js
SyntaxError: Unexpected token var
at Module._compile (module.js:439:25)
at Object.Module._extensions..js (module.js:474:10)
at Module.load (module.js:356:32)
at Function.Module._load (module.js:312:12)
at Function.Module.runMain (module.js:497:10)
at startup (node.js:119:16)
at node.js:901:3

Is there something actually wrong with the bash, or does node have a specific way of doing this? I used /bin/env so that I could have the proper form of "node" regardless of version.

Answer Source

It looks like you are trying to run node from within node. The error message came from node and it looks like node was trying to run the command /var/node/assets/js/update.js.

I would make the shebang line specify bash rather than node.

The top line

#!/usr/bin/env node

means that what follows should be JavaScript code, not bash.
