A pid of 413 means that when that process was fork()'ed there had been 412 other processes already created. But remember every time you type ls, you've run a process. 413 isn't a large pid at all. My linux box which I very rarely reboot is at PIDs that start at 20000 I'm surprised that any program you start after the boot process is as low as 412. ----- Original Message ----- From: "Silambu Chelvan" To: Sent: Wednesday, September 10, 2003 10:23 AM Subject: About PID...???!!! > Hi All, > > I have been using linux for quite some time.
