Sample code to call a shell script from CasperJS

casperShell.js

  // (…)
  var childProcess;
  try {
    childProcess = require("child_process");
  } catch (e) {
    this.log(e, "error");
  }
  if (childProcess) {
    childProcess.execFile("/bin/bash", ["mycommand.sh", args1, args2, args3], null, function (err, stdout, stderr) {
      this.log("execFileSTDOUT:", JSON.stringify(stdout), 'debug');
      this.log("execFileSTDERR:", JSON.stringify(stderr), 'debug');
    });
    this.log("Done", "debug");
  } else {
    this.log("Unable to require child process", "warning");
  }

https://github.com/ariya/phantomjs/blob/master/src/modules/child_process.js she's not documented :/ But you're right we don't need more thant Phantomjs'one

thanks for the script . my casperjs file is located in c://wamp/www what i want is to execute
"myexefile.exe -l username -p password -c myfile.txt [-t 10000]"
but there is no doc available or example . i just want to execute the above command and store the responce in var myvalue in casperjs plese help

I don't really understand how to incorporate the provided code into a Jasper test (using Jasper's promises, I guess). Would you mind providing an example wrapped inside a casper.then()?

What is the equivalent for slimerjs? I get the following error when I run the same script that passes with phantomjs under slimerjs.

FAIL Error: Module: Can not resolve "child_process" module required by main located at file:///usr/local/lib/node_modules/casperjs/bin/bootstrap.js
type: uncaughtError
file: functionalTestsWIP.js
error: {}
stack: not provided

any chance you know how to get the standout in casper.then?

Sample code:

casper.then(function(){
   childProcess.execFile("/bin/bash", ["mycommand.sh", args1, args2, args3], null, function (err, stdout, stderr)       {
      this.log("execFileSTDOUT:", JSON.stringify(stdout), 'debug');
      this.log("execFileSTDERR:", JSON.stringify(stderr), 'debug');
    });
});

casper.then(function(){});

I cannot get any stdout or stderr from the callback by running a bash script. but if I do simple commands like ls -l /usr, i can get the output.
