Server with the fringe on "top"...

Just stumbled on a much nicer, expanded version of the *nix command line tool top (process listing/manager tool), called htop.  Cool - what I especially like about it is its little graphical display of cpu usage meters for each individual processor in a machine; the rest looks similar to top but with highlighting and extra features - and all configurable.  And you can scroll up and down the processing listing too!

Looks like it's installed by default already on my Ubuntu machines, but not on my Macs.  (And for the record I think the output formatting in the OSX version of top is awful anyway!)  For that I found this guy's webpage offering a precompiled OSX binary (but you could compile it yourself if you prefer, see link at bottom of his page).

Here's a screenshot of what it looks like on one of our 8-processor Ubuntu cluster nodes...

(apologies for the title pun, couldn't help myself.  ;-)
