Hi Guys, How to understand kernel PID Understating, I have seen #ps -aux command show all user process and system process will show, I can't find Some PID is not there, How can I see Hidden process numbers
root ~ # ps -aux Warning: bad ps syntax, perhaps a bogus '-'? See http://procps.sf.net/faq.html USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.0 0.0 2928 1820 ?
