在 Java 中运行多个 linux 命令

Question

I'm pretty new to Java and I', currently trying to run multiple linux commands line through a function in Java.

For the function I am getting a string called "fileName". After that I want to change to a certain directory, execute an .sh and write it into a .txt file, let the thread sleep for 3 seconds so that it can write the text file properly, and finally press "q" to end the .sh execution. The .sh file has been programmed by someone else and it only seems to exit properly when "q" is pressed into the shell.

To clarify a little bit, although my code isn't finished I will post what I have.

public String getNum(String fileName) throws Exception{
Process p = null;
Runtime rt = Runtime.getRuntime();

try {
  p = rt.exec(new String[]{"cd /usr/local/bin", "./test_elanprv2.2.sh > {fileName}.txt", });

}catch (Exception e){

}

}

Thank you in advance!!
