Simple Library to make the process of executing system commands through java a simple task. The library is thread-safe, can be used to execute multiple commands asynchronously. ------ **How to** If you want to execute a command, and redirect the output to the `console`: try { CommandExecutor.execute("ping google.com"); } catch (IOException e) { e.printStackTrace(); } ------ However, this library gives you more control over the commands being executed; - You can use the `CommandBuilder` as *wrapper* for the parts that form the command line you want to execute; such as arguments (`CommandBuilder#withArgs`) and options(`CommandBuilder#withOptions`). - You can *redirect* the `standard` and `error` outputs to any object You want, just *implement* the `Appender` interface. - You can *retrieve* the `exit code` of the process, or *abort* the process, by simply using the `ProcessMonitor` and `ExecutionReport` objects. ------ An advanced example: Command cmd = new CommandBuilder().forCommandLine("ping").withArgs("google.com").build(); ExecutionOutputPrinter eop = new ExecutionOutputPrinter(new Appender() { @Override public void appendStdText(String text) { // your code to show std output lines. } @Override public void appendErrText(String text) { // your code to show error lines. } }); try { ProcessMonitor pMonitor = CommandExecutor.execute(cmd, null, eop); //execute the command, redirect the output to eop. ExecutionReport report = pMonitor.getExecutionReport(); //blocks until the process finishes or gets aborted. String commandLine = cmd.string(); int exitCode = report.exitValue(); System.out.printf("command line: %s\nexecution finished with exit code: %d\n\n", commandLine, exitCode); } catch (UnrecognisedCmdException e) { System.err.println(e); } to abort a running process (command), you can use the `ProcessMonitor` instance that you obtained previously: pMonitor.abort(); ----------
