Java run c program with options

Question

I have this code:

try {
    Process p = new ProcessBuilder(
            "/Applications/TorBrowser_en-US.app/Contents/MacOS/./tor",
            "-f /Applications/TorBrowser_en-US.app/Library/filetctor/torrc")
            .start();
    p.waitFor();
    int exitVal = p.exitValue();
    System.out.println("Process exitValue: " + exitVal);
} catch (IOException e) {
    System.out.println(e);
} catch (InterruptedException e) {
    System.out.println(e);
}

Every time i execute it, i get a 255 exitValue. The process doesn't run properly.

If i run the program with only:

Process p = new ProcessBuilder("/Applications/TorBrowser_en-US.app/Contents/MacOS/./tor").start();

The process runs correctly. But i need to use the -f option.

What is the problem? Am i writing it incorrectly?

The -f and the file path should almost certainly be separate parameters. — Joachim Sauer

Did you try to run the application on its own? What error does it return? Try and fetch it with getInputStream() or getErrorStream(). — Djon

Each argument should be a separate string, not all in a single space-separated string.

See the example in the documentation:

ProcessBuilder pb = new ProcessBuilder("myCommand", "myArg1", "myArg2");

Process p = new ProcessBuilder("/Applications/TorBrowser_en-US.app/Contents/MacOS/./tor", "-f", "/Applications/TorBrowser_en-US.app/Library/filetctor/torrc").start(); WORKS
