app.system: Is there a way to retrieve the results, the stdout, of this command

[Premiopolis]

I ran the following JSX from a Mac OS Photoshop custom HTML extension panel

function RunSomeCli(Cmd){  
  return(app.system(Cmd));  
}  
  
//Run some PHP and retrieve the results:  
RunSomeCLi("curl -A 'UserAgent' -d 'ThisParam=ThatValue' '[Path-To-Hosted-Php]'");  
//Returns 0.  That's it.  
  
//Then ran a test whether app.system works at all with this curl to download a file  
RunSomeCli("curl -A 'UserAgent' -o '/[PathToLocalDestFile].txt' 'http://[PathToHostedFile].txt'");  
//also Returns 0, but executes the download successfully.  

So the app.system works, and I'm able to run CLI commands, but thus far unable to retrieve stdout results.

Run Your binaries from HTML panel as standard NodeJS chidprocesses. Leave that old mastodon .jsx for the unavoidable tasks.

Yes, works great, but was curious if there might also be an option in the JSX/ExtendScript context.

Please try this, from: Re: Change foreground color according to clipboard

function getSystemCommandStdout (command)
{
    var stdout = "";
    var tempFile = new File (Folder.temp + "/temp.txt");
    app.system (command + " > " + tempFile.fsName);
    if (tempFile.open ("r"))
    {
        stdout = tempFile.read ();
        tempFile.close ();
        tempFile.remove ();
    }
    return stdout;
}

var result = getSystemCommandStdout ("curl -A 'UserAgent' -d 'ThisParam=ThatValue' '[Path-To-Hosted-Php]'";
$.write (result);

HTH,
