I start a gui app from a konsole window and it writes out totally useless information. I do not need that. Is there a way to stop this, once and for all? I tried disown, doesnt help. I guess 2>&1 >/dev/null might help but that's rather tedious :(
Edit: OK, let's get creative. One half of the answer is to use preexec (I use zsh but the net is full of bash preexec tricks) and use
ldd to detect libX11 (and what else?). Then http://stackoverflow.com/a/9188571/308851 shows how to create redirects to /dev/null. How can we expand this solution to work with programs having a shell script wrapper?
