Executing Unix Script through plink from JAVA Runtime

Question

I am using below code to trigger script of Unix through Java.I am not able to figure out why this command is not working.

    String cmd="E:\\plink.exe -ssh -l user -pw p123 10.xxx.xx.xx \"sh /home/try.sh\"";
    System.out.println(cmd);
    Process process=Runtime.getRuntime().exec(cmd) ;
    process.destroy();

Do i need to make some correction in it?

Answer 1

Runtime.exec only starts the specified program/process. You immediately destroy it before it has time to connect and send the commmand, as you want it to. At a minimum you should .waitFor() it to complete.

You don't say if the script produces (any) output. If it does and you want anything to happen with that output, like being displayed or saved someplace, you need to read from Process.getInputStream() and do your thing. Also if your script needs input (less common) you need to write it to .getOutputStream().
