Can you give an example of running a python script with execFile? I have tried using 'python myProgram.py' 'myProgram.py' and './myProgram.py' but I get an ENOENT error every time.
you can child_process.execFile('pwd',callback)
, check the directory, I guess it's not where you running your command
@scarrick68 have you tried?

How can I call the execFile method to run a bash script that returns a list of values?
My bash file (test.sh) returns a list of 8 values but the below script is printing only the last row of the output.
const { execFile } = require('child_process');
const child = execFile('./test.sh', (error,stdout,stderror) => {
if (error) {
throw error;
}
console.log(stdout);
});
Does it differenciate this 2 kind of errors:
- child_process didn't find your binary or the process broke;
- a "normal" error code was returned by your binary after execution
