public class Command
extends Object

Exec helper that allows easy handling of stdin, stdout, and stderr. Normally you have to worry about deadlock when dealing with those streams (as mentioned briefly in Process), so this class handles that for you.

exec

public static Command.Result exec(String[] command)
                           throws IOException,
                                  InterruptedException

Same as exec(command, null, new byte[0]).

Throws:

IOException

InterruptedException

                                  InterruptedException

Throws:

Create process command starting in the workingDir and providing stdin as input. This method blocks until the process exits. Stdout and stderr are available via Command.Result.getStdout() and Command.Result.getStderr(). Before using them, however, you should generally make sure that the process exited with a return code of zero, as other return codes typically indicate an error.

Throws:

IOException - if creating process fails

InterruptedException
