Ps

ps command stands for process status and it displays all the current running process in the Linux shell.

Basic Syntax¶

List all running processes:

      ps aux

  List all running processes including the full command string:

      ps auxww

  Search for a process that matches a string:

      ps aux | grep string

  List all processes of the current user in extra full format:

      ps --user $(id -u) -F

  List all processes of the current user as a tree:

      ps --user $(id -u) f

  Get the parent PID of a process:

      ps -o ppid= -p pid

  Sort processes by memory consumption:

      ps --sort size
