• Search for a process that matches a string (the brackets will prevent grep from matching itself):

ps aux | grep {{[s]tring}}

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

ps {{[-u|--user]}} $(id {{[-u|--user]}}) -F

• List all processes of the current user as a tree:

ps {{[-u|--user]}} $(id {{[-u|--user]}}) f

• Get the parent PID of a process:

ps {{[-o|--format]}} ppid= {{[-p|--pid]}} {{pid}}

• Sort processes by memory consumption:

ps --sort size
