[linux] How to redirect the output of an application in background to /dev/null

I would like to redirect the output generated from a background application in Linux to /dev/null.

I am using kate text editor and it prints all the debug messages on the terminal which I would like to redirect to /dev/null.

Any idea how to do it ?

Thanks

These will also redirect both:

yourcommand  &> /dev/null

yourcommand  >& /dev/null

though the bash manual says the first is preferred.
