If we could change the settings on the fly after that, all this would be a whole lot easier, but the OSX kernel locks them down somehow. BTW, I dunno if you read awk at all, but that awk command effectively says "print lines that contain = and do not contain #". You didn't try appending comments to the setting lines in your file did you? regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
