Can I write a bash script inside a Lambda function? I read in the aws docs that it can execute code written in Python, NodeJS and Java 8.

It is mentioned in some documents that it might be possible to use Bash but there is no concrete evidence supporting it or any example

Something that might help, I'm using Node to call the bash script. I uploaded the script and the nodejs file in a zip to lambda, using the following code as the handler. 

exports.myHandler = function(event, context, callback) {
  const execFile = require('child_process').execFile;
  execFile('./test.sh', (error, stdout, stderr) => {
    if (error) {
      callback(error);
    }
    callback(null, stdout);
  });
}

You can use the callback to return the data you need.
