Start a sh file from plugin

So i want to start a sh file from my plugin... I'm shutting the server down and after that i want the system to run a sh file and that sh file will update the plugins , world etc from a main directory and start the server again (already did this)! But how can i run a sh file through my plugin?

 

Did you taked a look at this? ProcessBuilder

 

So how would i start an sh with this?

 

http://grepcode.com/file/repository.grepcode.com/java/root/jdk/openjdk/6-b14/java/lang/Process.java

this allow to execute both unix and windows code with Runtime.getRuntime().exec("YOUR CODE REFERENCE AS STRING");
since this do allow to run "unwanted" native code from plugin, unlikely that plugin with such function will be ever approved.

 

It's a private plugin for my mmo server So but if the server is down, the plugin can't run the code? I mean if i start the copy code when the server is going down, the code will stop when the plugin is unloaded?

 

if server is down no code can be run.
you must execute shell code from separate application or at moment when server still running

 

Yeah so how would i manage this to work? How can i start a external sh file? Linux commandline is "./patch.sh"!

Runtime.getRuntime().exec("patch"); <--- Found this would that run the patch.sh in the main directory of the server?

test it yourself, it works like CMD on windows and shell on unix.

 

Having a problem:

Code:java

                                Bukkit.shutdown();
 
                                try {
 
                                    String path = serverName.toUpperCase();
 
                                    Process proc = Runtime.getRuntime().exec("path"/patch.sh"); //Whatever you want to execute
 
                                    BufferedReader read = new BufferedReader(new InputStreamReader(
 
                                    proc.getInputStream()));
 
                                } catch (IOException e) {
 
                                    System.out.println(e.getMessage());
 
                                }

When i shutdown the server after this the script starts but seem to stop? So does the Java Process need to be still open? Can you help?
