Hello nimafire,

I have a few to questions pose in response first:-Most importantly, What have you tried so far? This menu doesn't actually drive anything yet.

Ok, now i have new question, do we have other style more than dialog ?

i want to have something like ajax that show $STATUS in my menu and refresh every 5 min

Okay, so now I'm very confused. You didn't answer any of the questions and bring in something I'm not familiar with. What is ajax? Is it software, a command or a member of this community?

I'm not going to be able to help if you don't show what you have tried.

Hi,

Ajax is described here, I've heard of it but never used it myself.

ajax needs to call local code to call local code. Meaning: for every OS it connects to it has some kind of locally DIFFERENT "api" call to get what you want. Therefore, the call is platform dependent. Base java has as a last resort the system method/call: as one clumsy way to do what you want. In order to get you an answer we need:

platform this is going to run on (OS name version)

Examples of what I mean as the issue:

Code:

ps -ef | grep -v grep |  grep -q  crond

This lousy bit of code will probably work on most modern Unix OSes. It requires modern a grep (supports -q) so it will not work on some older systems.

Some OSes have a commands that shows service information: Solaris, Red Hat, and so on.
Solaris (from the command line:

Code:

svcs  /system/cron

OK let me answer your question as you ask me ,
i havent receive any error,
i want to code a shell script with dialog ,which can show status of service XYZ in the top part of screen,
question is, is it possible to show $STATUS which bind to :
service crond status
and show $STATUS in real time?
because this script can get status of crond ONLY when we run script,
