All Implemented Interfaces:

java.lang.Runnable

public class StreamGobbler

extends java.lang.Thread

Used to empty output and error buffers when running a Runtime.getRuntime.exec(..) operation.

See this article for original code listing and more information: When Runtime.exec() won't [javaworld.com].

Typically you would use this class in a manner similar to the following:

    Process proc = Runtime.getRuntime().exec(script);
   
    StreamGobbler errorGobbler = new StreamGobbler(proc.getErrorStream(), "ERROR");
    StreamGobbler outputGobbler = new StreamGobbler(proc.getInputStream(), "OUTPUT");
    
    errorGobbler.start();
    outputGobbler.start();
    
    int exitValue = proc.waitFor();
