[nycbug-talk] process tree viewing

[Isaac Levy]

Hey all,

I was just wondering- does anyone know of any good utilities to 
visualize a process tree, (beyond using grep and ps?)

I'm especially looking for a way to quickly visualize hierarchal 
relationships of processes- like tab indentation or somesuch.

--
Context:

With OSX, the 'Activity Monitor.app' has a sweet GUI feature for 
showing all processes, hierarchically-

I'm basically looking for an equivalent which runs from a shell, cross 
platform, i.e.:

--
PID-Name

0-kernel
	\_ 1-init
		\_ 1154-login
			\_ 1155-bash
		\_ 1156-login
			\_ 1157-bash
		\_ 1158-login
			\_ 1159-bash
--

Kindof a clumsy example, but it's the kind of output I'm trying to get.

If there's nothing for this, I'm pondering writing something here... 
(but somebody had to have done this before me?  It seems so darned 
basic?)

Any ideas or urls much appreciated!
