This is the default executor that does nothing but just executing the statements. TODO - This is not finished yet! @since 2.2 @version $Id: DefaultExecutor.java 587751 2007-10-24 02:41:36Z vgritsenko $
org.apache.commons.exec.DefaultExecutor
The default class to start a subprocess. The implementation allows to
- set a current working directory for the subprocess
- provide a set of environment variables passed to the subprocess
- capture the subprocess output of stdout and stderr using an ExecuteStreamHandler
- kill long-running processes using an ExecuteWatchdog
- define a set of expected exit values
- terminate any started processes when the main process is terminating using a ProcessDestroyer
The following example shows the basic usage:
```
 Executor exec = new DefaultExecutor(); CommandLine cl = new CommandLine("ls -l"); int exitvalue = exec.execute(cl); 
```
