Answer» When we execute “ps aux” in Linux terminal console, we can see multiple states of processes running in the SYSTEM under the STAT column. R: Process is running with CPU or WAITING for CPU (Running or Runnable) S: Process is waiting for the set event to complete, Like an input from terminal (SLEEP) D: Process is with uninterruptible sleep stats which cannot be changed or KILLED \ rollback. The only WAY to go AWAY is the reboot system. Z: Process in Zombie status means the process is already killed but process information and data still exist in the process table. T: Process either completed or terminated by the operating system or user. This is also known as Terminated / Completed. |
