I have several Linux (Ubuntu 10.04) processes running on my computer. If I start one of them, I can see the verbose of it on my terminal. I have an other process that start a dozen of those processes so that they run in background. However, I would like to watch the output of one of these processes to see if the output is still ok and there are no error message. I know I could send everything into a log message, however, this would just use too much disk space. So, is there a way to "catch" the output of a running process in Linux using it's process Id?
