Method Detail

execute

public static int execute(java.lang.String command,
                          byte[] stdin,
                          java.io.OutputStream os,
                          java.lang.String[] env)
                   throws java.io.IOException

Starts an external program (process) passing the specified input to the program and fills an OutputStream with the programs output. If an error occurs the content of stderr is also written to the OutputStream. This is ideal for offline processing of e programs output.

Parameters:

command - the complete command line to execute

stdin - data to fill the programs stdin, or null

os - an output stream which receives the programs output

env - an environment or null

Returns:

0 on succes or the programs exit code

Throws:

java.io.IOException - if an i/o error occurs

execute

public static int execute(java.lang.String command,
                          byte[] stdin,
                          java.io.OutputStream os,
                          java.lang.String[] env,
                          long timeout)
                   throws java.io.IOException

Starts an external program (process) passing the specified input to the program and fills an OutputStream with the programs output. If an error occurs the content of stderr is also written to the OutputStream. This is ideal for offline processing of e programs output.

Parameters:

command - the complete command line to execute

stdin - data to fill the programs stdin, or null

os - an output stream which receives the programs output

env - an environment or null

timeout - a timeout value in ms

Returns:

0 on succes or the programs exit code

Throws:

java.io.IOException - if an i/o error occurs

execute

public static int execute(java.lang.String command,
                          java.io.InputStream stdin,
                          java.io.OutputStream os,
                          java.lang.String[] env,
                          long timeout)
                   throws java.io.IOException

Starts an external program (process) passing the specified input to the program and fills an OutputStream with the programs output. If an error occurs the content of stderr is also written to the OutputStream. This is ideal for offline processing of e programs output.

Parameters:

command - the complete command line to execute

stdin - data to fill the programs stdin, or null

os - an output stream which receives the programs output

env - an environment or null

timeout - a timeout value in ms

Returns:

0 on succes or the programs exit code

Throws:

java.io.IOException - if an i/o error occurs

execute

public static int execute(java.lang.String command,
                          java.io.InputStream stdin,
                          java.io.OutputStream os,
                          java.lang.String[] env,
                          long timeout,
                          java.io.File dir)
                   throws java.io.IOException

Starts an external program (process) passing the specified input to the program and fills an OutputStream with the programs output. If an error occurs the content of stderr is also written to the OutputStream. This is ideal for offline processing of e programs output.

Parameters:

command - the complete command line to execute

stdin - data to fill the programs stdin, or null

os - an output stream which receives the programs output

env - an environment or null

timeout - a timeout value in ms

dir - a File object defining the current dir for the process

Returns:

0 on succes or the programs exit code

Throws:

java.io.IOException - if an i/o error occurs
