On FC4 with KDE, I ran ps -ef and noticed that there were many old /usr/bin/tail processes. They all looked like tail -f that I had run. I wrote a script to kill -9 them. I ran tests and found that if I exit tail -f with ctrl-c the processes disappears, but if I close a KDE window on a tail -f without ctrl.c, the processes persists. Is this the way it should be? Thanks for your comments. Mike.
