In order to directly run Node.js® script code from a JS7 shell job script, the recommended approach is to use a shebang that runs Node.js® as the interpreter of the script like this:
Code Block language js title Example how run Node.js® script code with a shebang linenumbers true #!/usr/bin/node var name = (process.env.name); var num = parseInt(process.env.num); //print value of variable console.log( name); console.log( num);
Alternatively, the Node.js® script can be executed from a file that has to be is located within reach of the JS7 Agent that runs the job:

In order to directly run Node.js® script code from a JS7 shell job script, the recommended approach is to use a shebang that runs Node.js® as the interpreter of the script like this:

Explanation:- If you consider this shebang replacement somewhat cryptic then add it to JS7 - Script Includes which are easily referenced from shell jobs, e.g. by using
##!include Node
//!include <name-of-script-include>
- The
node.exe
executable as available from the Node.js® installation is executed by the shebang.

In addition, a Node.js® script can be executed from a file located with the JS7 Agent that implements the job:
