How can you execute a Node.js script via a cron job?


Question

Quite simply, I have node script that I want to execute once a month.

30 6 1 * * node /home/steve/example/script.js

But this doesn't work, presumably because of path or the shell the command is being ran under. I've tried the following means of executing node via cron (tested with -v):

steve@atom:~$ node -v
v0.4.2

steve@atom:~$ sh node -v
sh: Can't open node

steve@atom:~$ bash node -v
/usr/local/bin/node: /usr/local/bin/node: cannot execute binary file

steve@atom:~$ /usr/local/bin/node -v
v0.4.2

steve@atom:~$ sh /usr/local/bin/node -v
/usr/local/bin/node: 1: Syntax error: "(" unexpected

steve@atom:~$ bash /usr/local/bin/node -v
/usr/local/bin/node: /usr/local/bin/node: cannot execute binary file

I've ran out of ideas to try, any advice?

Accepted Answer

just provide the full path to node /usr/local/bin/node in your cron job like:

30 6 1 * * /usr/local/bin/node /home/steve/example/script.js
90

Additionally, just put #!/usr/local/bin/node at the top of the script you want to execute. Then it will automatically know to execute the script with node. Make sure the file is executable as well.
