This question already has an answer here:
When I launch an application from terminal related to the window system, for example gnome or kde, then usually these applications send all sorts of junk messages in my terminal. How do I make these applications shut up?
For example if I type:
okular somepdf.pdf &
a window which shows the pdf file pops up and I can read the pdf next to my terminal, and when I am done I close.
Here is a typical example:
:~$ cd Documents :~/Documents$ okular equi.dvi &  5823
and when I close it sends this junk to the terminal:
:~/Documents$ okular(5823)/kdeui (kdelibs) KXMLGUIClient::~KXMLGUIClient: 0x2322528 deleted without having been removed from the factory first. This will leak standalone popupmenus and could lead to crashes. d d: command not found + Done okular equi.dvi + Done okular equi.dvi :~/Documents$
The only thing I would like to see is:
:~$ cd Documents :~/Documents$ okular equi.dvi & :~/Documents$
Perhaps that message was some bug, I do not care and I do not want to know about it.
Is it possible to suppress these messages?
