Hi,

I am a linux new user. I have some questions about ps -A in ubuntu v11.10. Command ps -A have four parameters are PID, TTY, TIME and CMD.

I have found out PID and CMD but I have not found TTY and TIME, it located in the path??? I need read file contains TTY and TIME.

Thank you so much!!!

TTY = Terminal attached to

Time = Duration Running. 00:00:00 denotes sleeping waiting on need : Disk write et cettera.
