Hy,I am having problems when trying to execute a command for konsole from java.
This is a part of my code
try{
Runtime.getRuntime().exec("konsole");
}
catch (IOException ex){ex.printStackTrace();}
this code opens the Linux konsole ; is the a method to append a command for Linux from java?
Thanks
OK
this is what I am trying to do : by pressing a button in a JFrame I want to start Snort (the exact command is snort -c /etc/snort/snort.conf )
What I want is the following: I press that button and the Konsole in Linux opens and that command to be executed
MY code is the following
try { Runtime.getRuntime().exec(" konsole -e snort -c /etc/snort/snort.conf")}
{catch(IOException ex) ex.printStackTrace()}
the command is executed , the Konsole window appears only for a second and closes , I NEED the window to stay open
Any suggestion is welcomed
Thanks

I would just use the Process.getInputStream() method to retrieve what Snort said and display that in a JTextArea or something... why bother launching it in a terminal?
I don't know if Snort is a daemon or what... if it's a daemon, you're not going to get much output from it... it'll fork itself into the background and exit.
If it isn't a daemon, then you can either just redirect the output to a file, a la:
konsole snort /etc/snort/snort.conf > /tmp/snort.out
and do a "tail" sort of monitoring on the file. You could also just keep that process up in a different thread, and use a timer to periodically update the output into a JTextArea (this would also allow you to be notified when the process ended). Finally, you could wrap your command in a script and execute it that way.
