Method Detail

exec

public static int exec(java.lang.String command)

Executes the specified string command in a separate process and causes the current thread to wait, if necessary, until the process represented by this Process object has terminated.

Parameters:

command - a specified system command

Returns:

the exit value of the process. By convention, 0 indicates normal termination and -1 indicates an exception

exec

public static int exec(java.lang.String command,
                       java.io.OutputStream out,
                       boolean autoFlush)

Executes the specified string command in a separate process and causes the current thread to wait, if necessary, until the process represented by this Process object has terminated.

Parameters:

command - a specified system command

out - the standard output of the running process will be transferred to the specified writer

autoFlush - if true, the output buffer will be flushed whenever a byte array is written, one of the println methods is invoked, or a newline character or byte ('\n') is written

Returns:

the exit value of the process. By convention, 0 indicates normal termination and -1 indicates an exception

exec

public static int exec(java.lang.String command,
                       java.io.OutputStream out,
                       boolean autoFlush,
                       int timeout)

Executes the specified string command in a separate process and causes the current thread to wait, if necessary, until the process represented by this Process object has terminated.

Parameters:

command - a specified system command

out - the standard output of the running process will be transferred to the specified writer

autoFlush - if true, the output buffer will be flushed whenever a byte array is written, one of the println methods is invoked, or a newline character or byte ('\n') is written

timeout - the process will be destroyed if the process runs longer than the specified time (in milliseconds)

Returns:

the exit value of the process. By convention, 0 indicates normal termination and -1 indicates an exception

exec

public static int exec(java.lang.String command,
                       java.io.OutputStream out,

Parameters:

command - a specified system command

out - the standard output of the running process will be transferred to the specified writer

error - the error output of the running process will be transferred to the specified writer
