Linux/OS X - Information similar to WRKACTJOB

["albartell" <albartell@xxxxxxxxx>]

I am looking to make the jump from Windows to Apple OS X in the next year.
The reason is because I believe I can get a better business minded OS to
work on.  This would mean I would expect it to be more stable (yes Windows
XP freezes up on me a lot still, and I need to do reboots on a regular basis
just to keep things running smoothly), and possible have better
business/developer features.  By business/developer features I start
thinking of the awesome utilities we have through WRKACTJOB where we can see
a crazy amount of data about any given process (library lists, open data
paths, full stack job log, job start time, etc).
 
Right now I have Ubuntu loaded in a VMWare session on my PC and am using it
as my pretend testing grounds for OS X (assuming they are fairly similar
enough because they are both based on *nix).  
 
I have found the "top" command that can display a list very similar to
WRKACTJOB, but it doesn't give you the ability to dig in further.  Anybody
else have input for me that knows both *nix and OS/400?
 
Thanks,
