hi everyone i'm a noob trying to learn unix language.. but seems like i got no leads on how to start..

i'm playing with the 'ps' command.. i'm trying to show the pid, ppid, username, command, cpu utilization (in desc order), process start time and process status.. all in a command.. am i able to do that..? cos i've been trying for days and cant really 'read' the manual..

any help or advice would be appreciated.. thanks..
