方法详细资料

exec

java.lang.Process exec(CommandLine cmd,
                       java.util.Map env)
                throws java.io.IOException

Launches the given command in a new process.

参数:

cmd - The command to execute

env - The environment for the new process. If null, the environment of the current process is used.

返回:

the newly created process

抛出:

java.io.IOException - if attempting to run a command in a specific directory

exec

java.lang.Process exec(CommandLine cmd,
                       java.util.Map env,
                       java.io.File workingDir)
                throws java.io.IOException

Launches the given command in a new process, in the given working directory.

参数:

cmd - The command to execute

env - The environment for the new process. If null, the environment of the current process is used.

workingDir - The directory to start the command in. If null, the current directory is used

返回:

the newly created process

抛出:

java.io.IOException - if trying to change directory

isFailure

boolean isFailure(int exitValue)

Checks whether exitValue signals a failure on the current system (OS specific).

Note that this method relies on the conventions of the OS, it will return false results if the application you are running doesn't follow these conventions. One notable exception is the Java VM provided by HP for OpenVMS - it will return 0 if successful (like on any other platform), but this signals a failure on OpenVMS. So if you execute a new Java VM on OpenVMS, you cannot trust this method.

参数:

exitValue - the exit value (return code) to be checked

返回:

true if exitValue signals a failure
