PowerShell call from NodeJS

Question

I am trying to get the owner of a file in Node.js on Windows. In the absence of win32api, I decided to use the PowerShell command:

powershell -Command "(get-acl test.txt).owner" 

This works fine from the command line and from the batch file, but just hangs with Node.js exec() :

 var exec = require('child_process').exec; exec('powershell -Command "(get-acl test.txt).owner"', function(err,sysout,syserr) { console.dir(sysout); }); 

The PowerShell process just starts and never ends.

Does anyone have:

• the idea of ​​why the team will not return to Node.js or preferably
• a sensible way to force a file owner with Node.js on Windows?

Answer 1

When you call Powershell, you need to close the input stream. You can try using caviar and use stdin.end() .

Another option is to call cmd /c dir /q <file> , but this output is verbose.
