ptree for linux

at work, I'm a UNIX administrator, but at home I use openSUSE 11. One of the commands that I use to assist me in trouble shooting A LOT is called ptree process tree. does anyone know of a ptree for linux? yes, I can just use ps -ef and see who the parent pid is and then 'ps -ef | grep <parent pid>' and so on. but ptree does it all for me and lays it out nice and neat. call me a whiner, but I miss ptree. please help.

thanks in advance

try:

ps --forest -eaf

thank you. I will try that when I get home from work.

what about "pstree -p"... give that a shot.

or better yet, change to gentoo (cos it has pstree command)
