Linux terminal command in Java does not work

I'm trying to execute a linux command in my java code. It needs to change permissions for some directory.

Here is my attempt:

String  Cmd = "echo myPassword | sudo -S chmod 777 -R /home/somePath";
Runtime runtime = Runtime.getRuntime();
Process proc = runtime.exec(Cmd);

The command held in String Cmd is working perfectly when I used it in terminal. But when I use it in my code nothing happens. There is no error or warning feedback that helps me to understand my mistake. What might be the problem?

Java will not magically select bash as your executable. You probably want to do something like

"bash -c <your command>"

See this question:

(Also the | is a bash-thing. Java won't magically create pipes between processes.)
