Create a ProcessBuilder that, on the appropriate platforms, sources the standard interactive profile for the user (i.e. ~/.bash_profile).

Parameters:

commands - a string array containing the program and its arguments

Returns:

a ProcessBuilder

getBuilderWithPipeSupport

public static ProcessBuilder getBuilderWithPipeSupport(String... commands)

Create a ProcessBuilder that, on the appropriate platforms, sources the standard interactive profile for the user (i.e. ~/.bash_profile) and supports the use of the pipe (|) redirection on platforms that allow it.

Parameters:

commands - a string array containing the program and its arguments

Returns:

a ProcessBuilder

getStdErr

public static List<String> getStdErr(Process process)

Get the stderr for process.

Parameters:

process -

Returns:

a collection of error lines

getStdOut

public static List<String> getStdOut(Process process)

Get the stdout for process.

Parameters:

process -

Returns:

a collection of output lines

isPidRunning

public static boolean isPidRunning(String pid)

Check if the process with the processId is running.

Parameters:

pid - Id for the input process.

Returns:

true if its running, false if not.

waitForSuccessfulCompletion

public static void waitForSuccessfulCompletion(Process process)

Similar to Process.waitFor() but will throw a RuntimeException if the process does not have an exit code of 0.

Parameters:

process -

getCurrentPid

public static String getCurrentPid()

Return the pid of the current process.

Returns:

pid.
