I like the idea of not relying on system(). In most respects, doing fork() + exec() ourselves seems superior. We can control where the output goes, what we do while waiting, etc. But system() runs the command through the shell, so that for example you don't have to invent your own way of splitting a string into words to be passed to exec[whatever](). I've never understood how you're supposed to get that behavior other than by calling system(). -- Robert Haas EDB: http://www.enterprisedb.com
