1. Top Processes

A. Keywords:

1.) top: Show a mixed processes list based on top cpu/memory usage.

1. top -m, top --memory to show processes ranked by memory usage

2. top -c, top --cpu, to show processes ranked by cpu usage

3. top -i, top --io, to show processes ranked by io usage with callback from top io trace collector.

Top IO requires [DTrace][Dtrace] and it would take a while to finish. The new callback design is to run the job in he background and post a notification (OSX 10.8+) using notification center. Click on the notification to show the result in alfred.
