The ps command - process showing up even after application is shut down
Hi all,

I'm very new to unix, I'm developing an application in Java, part of which requires me to check if a certain application is still running. In windows, I just use tasklist - if the application has been shut down it won't appear in the task list. I've been trying to use the ps command to try to achieve a simlar result but what I've found is that even after this application has been shut down, the ps command will list it Smilie.

Does anyone have any ideas about how I might be able to see if a particular application is running?

Thanks

Katie

EDIT: OK I've realised that the reason ps still shows the application is because its in the dock. How can I exclude processes open in the dock? Or can I?

tk_setappname

Tk_SetAppName(3)					       Tk Library Procedures						  Tk_SetAppName(3)

__________________________________________________________________________________________________________________________________________________

NAME

       Tk_SetAppName - Set the name of an application for 'send' commands

SYNOPSIS

       #include <tk.h>

       const char *
       Tk_SetAppName(tkwin, name)

ARGUMENTS

       Tk_Window tkwin (in)	      Token for window in application.	Used only to select a particular application.

       const char *name (in)	      Name under which to register the application.
_________________________________________________________________

DESCRIPTION

       Tk_SetAppName associates a name with a given application and records that association on the display containing with the application's main
       window.	After this procedure has been invoked, other applications on the display will be able to use the send command to invoke operations
       in  the	application.  If name is already in use by some other application on the display, then a new name will be generated by appending "
       #2" to name;  if this name is also in use, the number will be incremented until an unused name is found.  The return value from the  proce-
       dure is a pointer to the name actually used.

       If the application already has a name when Tk_SetAppName is called, then the new name replaces the old name.

       Tk_SetAppName also adds a send command to the application's interpreter, which can be used to send commands from this application to others
       on any of the displays where the application has windows.

       The application's name registration persists until the interpreter is deleted or the send command is deleted from interp,  at  which  point
       the  name is automatically unregistered and the application becomes inaccessible via send.  The application can be made accessible again by
       calling Tk_SetAppName.

       Tk_SetAppName is called automatically by Tk_Init, so applications do not normally need to call it explicitly.

       The command tk appname provides Tcl-level access to the functionality of Tk_SetAppName.
