Java processbuilder run cygiwn commands

Question

Trying to write code to run cygwin commands from java code using processbuilder. not sure what's wrong. Please help me, Thank in Advanced!!

following code

import java.io.*;

public class test_6 {
    public static void main(String[] args) throws Exception {
        ProcessBuilder buildercmd = new ProcessBuilder(
            "cmd.exe", "/c", "cd \"D:\\csi\" && dir" +
                    "&& dir");

        ProcessBuilder buildercygwin = new ProcessBuilder(
                "D:/app/Cygwin/bin/bash", "-c", "cd /cygdrive/D/csi/ && dir" +
                        "&& ls -l");

        buildercygwin.redirectErrorStream(true);
        Process p = buildercygwin.start();
        BufferedReader r = new BufferedReader(new InputStreamReader(p.getInputStream()));
        String line;
        while (true) {
            line = r.readLine();
            if (line == null) { break; }
            System.out.println(line);
        }
    }
}

it worked using cmd as you see on my code but some reason its not working using cygwin.

following output i am getting:

/usr/bin/bash: dir: command not found

try using the full path to dir => D:/app/Cygwin/bin/dir

cygwin has a dir.exe, for the windows version it is an internal commmand. source:

I tried that, 'D:/app/Cygwin/bin/dir' but still getting same error '/usr/bin/dir: cannot access cd /cygdrive/D/csi/ && dir&& ls -l: No such file or directory' Thank for your help.. – Jayraj Patel Jun 23 '15 at 11:43
Hi, that is a different error message: `usr/bin/dir: cannot access cd /cygdrive/D/csi/`, so your `dir` command is fine/found, it's another issue with your paths – codemonk113 Jun 23 '15 at 16:50
