Pass variable from JavaScript to Windows batch file

问题:

Is it possible to create a variable in JavaScript and pass it to a batch file? Just as a simple test echo a variable and move a file up a directory.

JavaScript.js

var s = "Gwen Stefani"; var myFile = "C:\\temp\\myfile.txt" myBat.execute(); 

myBat.bat

echo s  move myFile .. 

An alternative is to create a string which is saved out as a batch file and then executed, but I was wondering if if it could be done directly.

You can use command line arguments (as you are using exec I suppose this is node.js):

var s = "Gwen Stefani"; var myFile = "C:\\temp\\myfile.txt" const exec = require('child_process').exec; const child = exec('cmd /c myBat.bat '+ myFile+' '+s,     (error, stdout, stderr) => {         console.log(`stdout: ${stdout}`);         console.log(`stderr: ${stderr}`);         if (error !== null) {             console.log(`exec error: ${error}`);         } }); 

or for extendscript:

var s = "Gwen Stefani"; var myFile = "C:\\temp\\myfile.txt"; system.callSystem('cmd /c myBat.bat '+ myFile+' '+s'); 

and the bat file:

echo %2 move "%~1" .. 

(mv is unix command but not from windows shell)
